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. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39035 a95241bf-73f2-0310-859d-f6bbb57e9c96
