haiku/headers/private/media/MediaWriter.h
Stephan Aßmus 69372b5545 * Change the signature of the Writer plugins setup methods such
that they can modify the media_format passed in. For example they
   can store information in the user_data section. I don't actually
   use this anymore, but it may come in handy again.

AVFormatWriter:
 * Adjust the AVCodecContext flags not only for video, but also
   for audio streams (as the API example does). This mechanism
   may not yet work, since the AVCodecEncoder actually uses a
   different AVCodecContext instance.
 * Use the encodeInfo->flags and specify the key frame flag
   for the AVPacket. This finally makes videos encoded on Haiku
   seekable.
