com.xuggle.xuggler.IContainer

A file (or network data source) that contains one or more {@link IStream} objects of audio and video data.

Typical usage for reading looks like this:

   IContainer container = IContainer.make();   if (container.open("myfile.flv", IContainer.Type.READ, null) <0)    throw new RuntimeException("failed to open");   int numStreams = container.getNumStreams();   for(i = 0; i < numStreams; i++) {     IStream stream = container.getStream(i);     ...query IStream for stream information...   }   IPacket packet = IPacket.make();   while(container.readNextPacket(packet) >= 0)   {     ... Do something with the packet...   }   container.close();

Typical usage for writing looks like this (makes an FLV file with one audio track encoded as mp3 data):

   IContainer container = IContainer.make();   if (container.open("myfile.flv", IContainer.Type.WRITE, null) <0)    throw new RuntimeException("failed to open");   IStream stream = container.addNewStream(0);   IStreamCoder coder = stream.getStreamCoder();   coder.setCodec(ICodec.ID.CODEC_ID_MP3);   coder.setSampleRate(22050);   coder.setChannels(2);   coder.setBitRate(64000);   if (coder.open()<0) throw new RuntimeException("could not open coder");  if (container.writeHeader() < 0) throw new RuntimeException();   IPacket packet = IPacket.make();   while( ... have more data to process ... ) {     then assuming it generated an IPacket for you...     if (container.writePacket(packet)<0)       throw new RuntimeException("could not write  packet");   }   if (container.writeTrailer() <0) throw new RuntimeException();   container.close();
