Revert the Codec Kit.

All of Barrett's individual reverts have been squashed into this
one commit, save a few actual bugfixes.

Change-Id: Ib0a7d0a841d3ac40b1fca7372c58b7f9229bd1f0

Codec Kit: Introduce BCodecKit namespace

ffmpeg: Update class names

Codec Kit: Rename files

ffmpeg: Move AVCodecWriter to BMetaData

AVFormatWriter: Rename fContext to fFormatContext

* Seriously, this naming is bad.

AVFormatWriter: Fix bad error checking

* Review by Markus Overhagen, Thanks!
* Renamed fHeaderWritten variable to fCodecOpened too

AVFormatWriter: Safeness after avformat_write_header fails

* The ffmpeg documentation explicit forbid to write the trailer
when the header write failed.
* Fixes #12678.

ffmpeg: don't use deprecated API in AVCodecDecoder.

* 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.

* Do no manually allocate the buffer for the
ByteIOContext. libavformat may reallocate it
on demand, we need to use the matching allocation
methods.
* Init the ByteIOContext with the proper "write flag".
This solves a busy loop when writing the trailer of
MKV files, since the first buffer was initially skipped
and the MKV muxer can not seek back in the stream
where it wants.
* Get rid of the fCalculatePTS member, and calculate
PTS of audio packets as well. I don't remember why
I prevented that, however VLC complains about audio
packets having wrong PTS (with or without this change)
Our own MediaPlayer plays videos generated by (a modified)
Clockwerk at least once, but seeking subsequently fails.

* Also pass the media_codec_info to the Writer::AllocateCookie(), since that
info is not part of the media_format otherwise.
* Finished enough in the AVFormatWriter and AVCodecEncoder that we can now
actually create AVIs and MPGs and encode MPEG1, MPEG2 and MPEG4 video.
But no audio as of yet. Also, there is no bit-rate/quality setup, so it seems
libavformat is using the least possible bit-rate/quality.
* Enable some more muxers and encoders in the FFmpeg libs.
* Uses pixel format conversion from libswsscale, need to read the documentation
again, but I think it makes the plugin GPL.
* Fixed includes in libswscale/swscale.h, this is now an unmodified FFmpeg 0.5
header again (AFAICT).

This should fix the GCC 4 build. The avformat code expects a non-const buffer
for the write() hook.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32037 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Tweaked the Writer API. Basically, we need an Init() method that takes the
media_file_format as input, so that the Writer knows what kind of file is
needed.
* Also, since information about the stream format is going to be needed at the
Writer level as well, the AllocateCookie() method gets the stream
media_format.
* Fleshed out some aspects of AVFormatWriter, many TODOs are left.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32025 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented static Write and Seek hooks to be passed to libavformat...


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32018 a95241bf-73f2-0310-859d-f6bbb57e9c96

* 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.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32013 a95241bf-73f2-0310-859d-f6bbb57e9c96

Let's call it WriteChunk() instead of WriteNextChunk() and make the signature
consistent everywhere (according to BMediaTracker::WriteChunk()).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31987 a95241bf-73f2-0310-859d-f6bbb57e9c96

Stubbed out Writer and WriterPlugin implementation. So far, Clockwerk shows
"AVI (Audio Video Interleave)" in the available output formats popup... :-)
