haiku/headers/private/media/WriterPlugin.h
Stephan Aßmus fa770e4c84 * Writer::WriteChunk() takes media_encode_info* instead of flags.
* Improved Encoder API towards what we need for the get_next_encoder() variants
  and the BMediaTrack API.
* Implemented the rest of MediaWriter. Still undecided what to make of
  AddTrackInfo(). BMediaEncoder has that as well, which hints that this is
  something the Encoder needs to support. But it could also be that this is
  only possible to support in Writer.
* Wired a lot of previously unimplemented methods in BMediaFile and BMediaTrack
  needed for write support. If I have not overlooked anything, only the
  parameter stuff is still unimplemented now.

This is all untested, since the FFMpeg Encoder and Writer are still only stubs.
