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.

BMediaFiles and about BMediaTracks in BMessages. As an
example, one can get chapter meta-data or the language
name of an audio-track.

* Small coding style cleanups in the .cpp
* When reading raw chunks, keep fCurrentFrame updated anyway
* When decoding frames and chunks, don't change the meaning of fCurrentTime,
it's supposed to be the start time of the next chunk/frame, same as
CurrentFrame(), not the time of the frame/chunk we just decoded/read.
BMediaTrack::CurrentFrame() is actually documented like this in the BeBook,
but CurrentTime() is not. However, when seeking to a specific time, it is
understood that this is the time of the next frame/chunk. If we decode/read
it and set fCurrentTime to the start_time as specified in the media_header,
it would actually not change for the first frame/chunk after seeking.
To be able to know the duration of chunks, fWriterFormat had to be changed
to just fFormat and is now used for decoding as well.
* Simplified handling of media_header in some methods, saves one assignment.
These changes are not so well tested, yet.

* 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.

to provide a format conversion to the requested raw format.
Added a few workarounds for applications that don't requst the required format
but instead assume to get a specific one.
