No, I haven't given it any thought and don't understand very much about it
either. I am considering to import libx264 alongside the ffmpeg libs and
perhaps even some more like theora and so on (which are already imported at a
different place) to enable the support for these external libraries in the
avcodec/avformat libs. Then one could most easily offer for example x264
encoding, and while doing so one could see what deficiencies are in the current
API. On the other hand I wanted to look into rewriting the MediaPlayer playback
backend (the node synchronization part), since I am not happy with it yet. It's
somewhat too complicated on the one hand, and doesn't offer some other features
at the same time. And while working on MediaPlayer I could make it more
pleasant to use by fixing some of the many reported issues.
Best regards,
