The emphasis is on + showing simple examples of various aspects of the servers capabilities + rather than on focussing on the MLT++ API. + + +THE BASIC CUSTOM SERVER + + The most basic custom server exposes the entire DVCP protocol and is roughly + equivalent to the miracle server iteself, but in this case, it lacks the + initialisation from /etc/miracle.conf and the port is hardcoded to 5290: + + #include + using namespace std; + + #include + using namespace Mlt; + + int main( int argc, char **argv ) + { + Miracle server( "miracle++", 5290 ); + if ( server.start( ) ) + { + server.execute( "uadd sdl" ); + server.execute( "play u0" ); + server.wait_for_shutdown( ); + } + else + { + cerr << "Failed to start server" << endl; + } + return 0; + } + + Note that after the server is started, this example submits the hard coded + commands specified - further units and property settings can of course be + specified via the DVCP protocol. + + To specify initial DVCP commands from /etc/miracle.conf, it is sufficient to + specify an additional argument in the server constructor. + + The wait_for_shutdown call is not required if the server is integrated in + a user interface application. + + +CUSTOMISATION + + This document focusses on the following areas of customisation: + + * the Miracle server class + * extending the command set + * accessing the units + * the Response object + * handling pushed westley documents + * accessiving events + + +THE MIRACLE SERVER CLASS + + The full public interface of the server is as follows: + + class Miracle : public Properties + { + public: + Miracle( char *name, int port = 5290, char *config = NULL ); + virtual ~Miracle( ); + mlt_properties get_properties( ); + bool start( ); + bool is_running( ); + virtual Response *execute( char *command ); + virtual Response *received( char *command, char *doc ); + virtual Response *push( char *command, Service *service ); + void wait_for_shutdown( ); + static void log_level( int ); + Properties *unit( int ); + }; + + The focus of this document is on the 3 virtual methods (execute, received and + push). Some further information is provided about the unit properties method + and the types of functionality that it provides. + + +EXTENDING THE COMMAND SET + + The simplest customisation is carried out by overriding the the 'execute' + method - the following shows a simple example: + + #include + #include + #include + using namespace std; + + #include + #include + using namespace Mlt; + + class Custom : + public Miracle + { + public: + Custom( char *name = "Custom", int port = 5290, char *config = NULL ) : + Miracle( name, port, config ) + { + } + + Response *execute( char *command ) + { + cerr << "command = " << command << endl; + return Miracle::execute( command ); + } + }; + + int main( int argc, char **argv ) + { + Custom server( "miracle++", 5290 ); + if ( server.start( ) ) + { + server.execute( "uadd sdl" ); + server.execute( "play u0" ); + server.wait_for_shutdown( ); + } + else + { + cerr << "Failed to start server" << endl; + } + return 0; + } + + All this does is output each command and pass control over to the original + implementation. + + When you execute this, you will see the following output: + + (5) Starting server on 5290. + command = uadd sdl + (5) miracle++ version 0.0.1 listening on port 5290 + command = play u0 + (7) Received signal 2 - shutting down. + + Note that all commands except the PUSH are passed through this method before + they are executed and this includes those coming from the main function itself. + + +ACCESSING UNIT PROPERTIES + + A unit consists of two objects - a playlist and a consumer. Your custom + server can access these by obtaining the Properties object associated to a unit + via the 'unit' method. + + As a simple example we can replace our execute method above with the following: + + Response *execute( char *command ) + { + if ( !strcmp( command, "debug" ) ) + { + int i = 0; + while( unit( i ) != NULL ) + unit( i ++ )->debug( ); + return new Response( 200, "Diagnostics output" ); + } + return Miracle::execute( command ); + } + + When this runs and you send a 'debug' command via DVCP, the server will output + some information on stderr, like: + + (5) Starting server on 5290. + (5) Server version 0.0.1 listening on port 5290 + (5) Connection established with localhost (7) + Object: [ ref=3, unit=0, generation=0, constructor=sdl, id=sdl, arg=(nil), + consumer=0x80716a0, playlist=0x807f8a8, root=/, notifier=0x8087c28 ] + (6) localhost "debug" 100 + + You can extract the objects using: + + Playlist playlist( ( mlt_playlist )( unit( i )->get_data( "playlist" ) ) ); + Consumer consumer( ( mlt_consumer )( unit( i )->get_data( "consumer" ) ) ); + + and use the standard MLT++ wrapping methods to interact with them or you can + bypass these and using the C API directly. + + Obviously, this opens a lot of possibilities for the types of editing operations + than can be carried out over the DVCP protocol - for example, you can attach filters + apply mixes/transitions between neighbouring cuts or carry out specific operations + on cuts. + + +THE RESPONSE OBJECT + + The example above doesn't do anything particularly useful - in order to extend + things in more interesting ways, we should be able to carry information back to + the client. In the code above, we introduced the Response object to carry an + error code and a description - it can also be used to carry arbitrary large + blocks of data. + + Response *execute( char *command ) + { + Response *response = NULL; + if ( !strcmp( command, "debug" ) ) + { + response = new Response( 200, "Diagnostics output" ); + for( int i = 0; unit( i ) != NULL; i ++ ) + { + Properties *properties = unit( i ); + stringstream output; + output << string( "Unit " ) << i << endl; + for ( int j = 0; j < properties->count( ); j ++ ) + output << properties->get_name( j ) << " = " << properties->get( j ) << endl; + response->write( output.str( ).c_str( ) ); + } + } + return response == NULL ? Miracle::execute( command ) : response; + } + + Now when you connect to the server via a telnet session, you can access the + 'debug' command as follows: + + $ telnet localhost 5290 + Trying 127.0.0.1... + Connected to localhost (127.0.0.1). + Escape character is '^]'. + 100 VTR Ready + debug + 201 OK + Unit 0 + unit = 0 + generation = 0 + constructor = sdl + id = sdl + arg = + + Note that the '200' return code specified is automatically promoted to a 201 + because of the multiple lines. + + Alternatively, you can invoke response->write as many times as you like - each + string submitted is simply appended to the object in a similar way to writing + to a file or socket. Note that the client doesn't receive anything until the + response is returned from this method (ie: there's currently no support to + stream results back to the client). + + +HANDLING PUSHED DOCUMENTS + + The custom class receives PUSH'd westley either via the received or push + method. + + The default handling is to simply append a pushed document on to the end of + first unit 0. + + You can test this in the server defined above from the command line, for + example: + + $ inigo noise: -consumer valerie:localhost:5290 + + By default, the 'push' method is used - this means that the xml document + received is automatically deserialised by the server itself and then offered + to the push method for handling - an example of this would be: + + Response *push( char *command, Service *service ) + { + Playlist playlist( ( mlt_playlist )( unit( 0 )->get_data( "playlist" ) ) ); + Producer producer( *service ); + if ( producer.is_valid( ) && playlist.is_valid( ) ) + { + playlist.lock( ); + playlist.clear( ); + playlist.append( producer ); + playlist.unlock( ); + return new Response( 200, "OK" ); + } + return new Response( 400, "Invalid" ); + } + + With this method, each service pushed into the server will automatically + replace whatever is currently playing. + + Note that the 'received' method is not invoked by default - if you wish to + receive the XML document and carry out any additional processing prior to + processing, you should set the 'push-parser-off' property on the server to 1. + This can be done by placing the following line in your classes constructor: + + set( "push-parser-off", 1 ); + + When this property is set, the received method is used instead of the push - + in this scenario, your implementation is responsible for all handling + of the document. + + To simulate this, you can try the following method: + + Response *received( char *command, char *document ) + { + cerr << document; + Producer producer( "westley-xml", document ); + return push( command, &producer ); + } + + When you push your videos in to the server via the inigo command above (or + from other tools, such as those in the shotcut suite), you will see the xml + in the servers stderr output. If you need to carry out some operations on the + xml document (such as replacing low quality videos used in the editing process + with their original) the received mechanism is the one that you would want to + use. + + +OTHER MANIPULATIONS + + What you do with the received MLT Service is largely up to you. As shown above, + you have flexibility in how the item is scheduled and you can carry out + manipulations on either the xml document and/or the deserialised producer. + + Typically, shotcut and inigo produce 'tractor' objects - these can be easily + manipulated in the push method - for example, to remove a track from the + output, we could do something like: + + Response *push( char *command, Service *service ) + { + Playlist playlist( ( mlt_playlist )( unit( 0 )->get_data( "playlist" ) ) ); + Tractor *tractor( *service ); + if ( tractor.is_valid( ) && playlist.is_valid( ) ) + { + // Remove track 2 (NB: tracks are indexed from 0 like everything else) + Producer *producer = tractor.track( 2 ); + Playlist track( producer ); + + // If we have a valid track then hide video and audio + // This is a bit pattern - 1 is video, 2 is audio + if ( track.is_valid( ) ) + track.set( "hide", 3 ); + + // You need to delete the reference to the playlist producer here + delete producer; + + // Play it + playlist.lock( ); + playlist.clear( ); + playlist.append( producer ); + playlist.unlock( ); + return new Response( 200, "OK" ); + } + return new Response( 400, "Invalid" ); + } + + +EVENT HANDLING + + The MLT framework generates events which your custom server can use to do + various runtime manipulations. For the purpose of this document, I'll focus + on 'consumer-frame-render' - this event is fired immediately before a frame + is rendered. + + See example in test/server.cpp + + +DISABLING DVCP + + In some cases, it is desirable to fully disable the entire DVCP command set + and handle the PUSH in an application specific way (for example, the shotcut + applications all do this). The simplest way of doing this is to generate a + response that signifies the rejection of the command. In this example, the + 'shutdown' command is also handled: + + Response *execute( char *command ) + { + if ( !strcmp( command, "shutdown" ) ) + exit( 0 ); + return new Response( 400, "Invalid Command" ); + } + + If you use this method in the code above, your server does nothing - no units + are defined, so even a PUSH will be rejected. + + + diff --git a/HOWTO b/HOWTO new file mode 100644 index 0000000..dbeca9a --- /dev/null +++ b/HOWTO @@ -0,0 +1,473 @@ +INTRODUCTION +------------ + + This document provides a brief tutorial on the use of the mlt++ wrapper + and bindings. + + +Hello World +----------- + + The mlt++ wrapper is a c++ wrapper for the mlt C library. As such, it + provides clean C++ access to the underlying library. + + An example of use is as follows: + + #include + using namespace Mlt; + + int main( void ) + { + Factory::init( ); + Producer p( "pango:", "Hello World" ); + Consumer c( "sdl" ); + c.connect( p ); + c.run( ); + return 0; + } + + This is a fairly typical example of mlt++ usage - create a 'producer' (an + object which produces 'frames'), create a 'consumer' (an object which consumes + frames), connect them together, start the consumer and wait until done (here + we just wait for the user to close the window). + + In this case, we construct a window as a consumer using the 'sdl' consumer + (SDL is a standard portable library which provides platform independent + access to accelerated video display and audio) and use the 'pango' + producer to generate frames with the words 'Hello World' (pango is a + library from the gtk toolkit). + + The main point of this example is to show that mlt uses existing libraries + to provide its functionality - this keeps the framework itself very small. + + Note that mlt is designed to be housed in GUI or server type applications - + typically, applications don't wait around for the consumer to be stopped in + the manner shown. + + So far, we've introduced the Producer and Consumer mlt classes. We'll cover + each of these in more detail later in the tutorial, but for now, we'll + briefly cover the remaining classes. + + +Playlists +--------- + + Another simple class is the Playlist - this is direct extension of Producer + and it allows you to maintain a list of producer objects. + + As a simple example of the Playlist in action, we'll convert the example + above into an application which plays multiple video or audio files. + + #include + using namespace Mlt; + + int main( int argc, char **argv ) + { + Factory::init( ); + Playlist list; + for ( int i = 1; i < argc; i ++ ) + { + Producer p( argv[i] ); + if ( p.is_valid( ) ) + list.append( p ); + } + Consumer c( "sdl" ); + c.connect( list ); + c.run( ); + return 0; + } + + Now you can run the program as: + + ./player *.avi *.mp3 *.jpg etc + + In this case, we construct a playlist by simply appending producers to it. + Notice that although the scope of the Producer is limited to the inner + for loop, we can safely add it to the playlist - this is due to the fact + that all mlt objects maintain reference counts and no object is really + destroyed until all the references are gone. In this case, when the list + object goes out of scope, all the producers we created will automatically + be destroyed. + + +Filters +------- + + So far, we've shown how you can load and play media. We've given a brief + intro to the Playlist container, now it's time to start manipulating + things... + + For the next example, I'll add a 'watermark' to the video - a watermark + is used by broadcasters to brand the channel and normally consists of a + logo of some sort. We'll just use some black text on a partially + transparent red background. + + #include + using namespace Mlt; + + int main( int argc, char **argv ) + { + Factory::init( ); + Playlist list; + for ( int i = 1; i < argc; i ++ ) + { + Producer p( argv[i] ); + if ( p.is_valid( ) ) + list.append( p ); + } + Filter f( "watermark", "pango:" ); + f.set( "producer.text", "MLT++" ); + f.set( "producer.fgcolour", "0x000000ff" ); + f.set( "producer.bgcolour", "0xff000080" ); + list.attach( f ); + Consumer c( "sdl" ); + c.connect( list ); + c.run( ); + return 0; + } + + Notice that the watermark filter reuses the 'pango' producer we showed in the + first example. In fact, you could use any producer here - if you wanted to + use a graphic or a video, you would just construct the filter with a full path + to that as the second argument. + + We manipulate the filter using the set method - this method was also shown + in the first example. + + Finally, we attach the filter to the playlist. This ensure that all frames + that are obtained from the playlist are watermarked. + + +Cuts +---- + + When you add a clip to a playlist, the a cut object is created - this is merely a + wrapper for the producer, spanning the specified in and out points. + + Whenever you retrieve a clip from a playlist, you will always get a cut object. + This allows you to attach filters to a specific part of a producer and should + the position of the cut in the playlist change, then the filter will remain + correctly associated to it. + + A producer and a cut are generally identical in behaviour, but should you need to + distinguish between them, you can use: + + if ( producer.is_cut( ) ) + + and to retrieve the parent of a cut, you can use: + + Producer parent = producer.parent_cut( ); + + Filters that are attached directly to a parent are executed before any filters + attached to the cut. + + +Tractor +------- + + A tractor is an object that allows the manipulation of multiple video and audio + tracks. + + Stepping away from the player example we've been tinkering with for a minute, + let's assume we want to do something like dub a video with some audio. This + a very trivial thing to do: + + Tractor *dub( char *video_file, char *audio_file ) + { + Tractor *tractor = new Tractor( ); + Producer video( video_file ); + Producer audio( audio_file ); + tractor->set_track( video, 0 ); + tractor->set_track( audio, 1 ); + return tractor; + } + + That's all that needs to be done - you can now connect the returned object to a + consumer, or add it to a playlist, or even apply it as a track to another tractor. + + +Transition +---------- + + Let's now assume we want to mix the audio between two tracks - to do this, we + need to introduce the concept of a transition. A transition in mlt is a service + which combines frames from two producers to produce a new frame. + + Tractor *mix( char *video_file, char *audio_file ) + { + Tractor *tractor = new Tractor( ); + Transition mix( "mix" ); + Producer video( video_file ); + Producer audio( audio_file ); + tractor.set_track( video, 0 ); + tractor.set_track( audio, 1 ); + tractor.field.plant_transition( mix, 0, 1 ); + return tractor; + } + + The tractor returned will now mix the audio from the original video and the + audio. + + +Mix +--- + + There is a convenience function which simplifies the process of applying + transitions betwee adjacent cuts on a playlist. This is often preferable + to use over the constuction of your own tractor and transition set up. + + To apply a 25 frame luma transition between the first and second cut on + the playlist, you could use: + + Transition luma; + playlist.mix( 0, 25, luma ); + + +Events +------ + + Typically, applications need to be informed when changes occur in an mlt++ object. + This facilitates application services such as undo/redo management, or project + rendering in a timeline type widget and many other types of operations which an + application needs. + + As an example, consider the following: + + class Westley + { + private: + Consumer consumer; + Tractor &tractor; + public: + Westley( MltTractor &tractor ) : + tractor( tractor ), + consumer( "westley" ) + { + consumer.connect( tractor ); + tractor.listen( tractor, "producer-changed", + ( mlt_listener )Westley::listener ); + } + + static void listener( Properties *tractor, Westley *object ) + { + object->activate( ); + } + + void activate( ) + { + consumer.start( ); + } + }; + + Now, each time the tractor is changed, the westley representation is output to + stderr. + + +Servers and Westley Docs +------------------------ + + One of the key features of MLT is its server capabilities. This feature + allows you to pass westley documents seamlessly from one process to + another and even to different computers on your network. + + The miracle playout server is one such example of an application which + uses this functionality - you can build your own servers into your own + processes with ease. + + A server process would be running as follows: + + #include + using namespace Mlt; + + int main( void ) + { + Miracle miracle( "miracle", 5250 ); + miracle.start( ); + miracle.execute( "uadd sdl" ); + miracle.execute( "play u0" ); + miracle.wait_for_shutdown( ); + return 0; + } + + Typically, when you have an MLT object such as a producer or a playlist, + you can send a westley representation of this to a running server with: + + Conumser valerie( "valerie", "localhost:5250" ); + valerie.connect( producer ); + valerie.start( ); + + The effect of the push will be to append the producer on to the first + unit (u0). + + You can completely customise the miracle server - an example of this + is shown below. + + +That's All Folks... +------------------- + + And that, believe it or not, is a fairly complete summary of the classes you'll + typically be interfacing with in mlt++. Obviously, there's a little more to it + than this - a couple of intrisinc classes have been glossed over (notably, the + Properties and Service base classes). The next section will cover all of the + above, but in much more detail... + + +DIGGING DEEPER +-------------- + + The previous section was designed to give you a whistle stop tour through the major + framework classes. This section will take you through the scenic route. + + +Introducing Base Classes +------------------------ + + Services in mlt are the collective noun for Producers, Filters, Transitions and + Consumer. A Service is also the base class from which all of these classes + extend. It provides the basic connectivity which has been shown throughout the + examples in the previous section. + + Properties are the main way in which we communicate with the Services - + essentially, it provides get/set methods for named values. All services extend + Properties. + + +Properties +---------- + + Properties provide the general mechanism for communicating with Services - + through the Properties interface, we are able to manipulate and serialise + a services state. + + For example, to dump all the properties to stdout, you can use something + like: + + void dump( Properties &properties ) + { + for ( int i = 0; i < properties.count( ); i ++ ) + cout << Properties.get_name( i ) << " = " << Properties.get( i ) << endl; + } + + Note that the properties object handles type conversion, so the following + is acceptable: + + properties.set( "hello", "10.5" ); + int hello_int = properties.get_int( "hello" ); + double hello_double = properties.get_double( "hello" ); + + A couple of convenience methods are provide to examine or serialise property + objects. + + For example: + + properties.debug( ); + + will report all serialisable properties on stderr, in the form: + + Object: [ ref=1, in=0, out=0, track=0, u=75, v=150, _unique_id=15, + mlt_type=filter, mlt_service=sepia ] + + +Services +-------- + + Typically, all the services are constructed via the specific classes + constructor. Often, you will receive Service objects rather than their + specific type. In order to access the extended classes interface, + you will need to create a reference. + + For example, given an arbitrary Service object, you can determine its + type by using the type method - this will return a 'service_type' which + has values of producer_type, filter_type etc. Alternatively, you can + create a wrapping object and check on its validity. + + bool do_we_have_a_producer( Service &service ) + { + Producer producer( service ); + return producer.is_valid( ); + } + + +Events +------ + + +Servers and Westley Docs +------------------------ + + For various reasons, you might want to serialise a producer to a string. + To do this, you just need to specify a property to write to: + + Consumer westley( "westley", "buffer" ); + westley.connect( producer ); + westley.start( ); + buffer = westley.get( "buffer" ); + + You can use any name you want, and you can change it using the "resource" + property. Any name with a '.' in it is considered to be a file. Hence, you + can use a westley consumer to store multiple instances of the same MLT + object - useful if you want to provide undo/redo capabilities in an + editing application. + + Should you receive an xml document as a string, and you want to send it + on to a server, you can use: + + Conumser valerie( "valerie", "localhost:5250" ); + valerie.set( "westley", buffer ); + valerie.start( ); + + If you need to obtain an MLT object from a string: + + Producer producer( "westley-xml", buffer ); + + The following shows a working example of an extended server: + + class ShotcutServer : public Miracle + { + public: + ShotcutServer( char *id, int port ) : + Miracle( id, port ) + { + } + + void set_receive_doc( bool doc ) + { + set( "push-parser-off", doc ); + } + + // Reject all commands other than push/receive + Response *execute( char *command ) + { + valerie_response response = valerie_response_init( ); + valerie_response_set_error( response, 400, "Not OK" ); + return new Response( response ); + } + + // Push document handler + Response *received( char *command, char *doc ) + { + valerie_response response = valerie_response_init( ); + // Use doc in some way and assign Response + if ( doc != NULL ) + valerie_response_set_error( response, 200, "OK" ); + return new Response( response ); + } + + // Push service handler + Response *push( char *command, Service *service ) + { + valerie_response response = valerie_response_init( ); + // Use service in some way and assign Response + if ( service != NULL ) + valerie_response_set_error( response, 200, "OK" ); + return new Response( response ); + } + }; + + NB: Should you be incorporating this into a GUI application, remember that the + execute, received and push methods are invoked from a thread - make sure that + you honour the locking requirements of your GUI toolkit before interacting with + the UI. + + diff --git a/LGPL b/LGPL new file mode 100644 index 0000000..fc8a5de --- /dev/null +++ b/LGPL @@ -0,0 +1,165 @@ + GNU LESSER GENERAL PUBLIC LICENSE + Version 3, 29 June 2007 + + Copyright (C) 2007 Free Software Foundation, Inc. + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + + This version of the GNU Lesser General Public License incorporates +the terms and conditions of version 3 of the GNU General Public +License, supplemented by the additional permissions listed below. + + 0.
