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

Reintroduced keeping the state of failed initialization.
As Stephan said, some apps ignore the return value of Encode(),
and since _OpenCodecIfNeeded() is called from there, this could
cause wasting of cpu cycles.

AVCodecEncoder: avcodec_close() is deprecated.
A codec context cannot be reopened, anymore.
Reorganize code accordingly.
Remove usage of the AVFormat context (which was not enabled, anyway) since it's no longer possible to do that.
Use av_frame_free() instead of av_free()

Try to use the ffmpeg api more correctly:
call avcodec_receive_packet() in a loop, drain and flush the internal buffers.
Introduced private method to improve code readability (hopefully).

AVCodecEncoder: Rename fContext to fCodecContext

ffmpeg: Remove obsolete code

AVCodecEncoder should not know the format

Initial implementation of BMediaEncoder

* People interested, please review!
* This is based on the patch from Fredrik Moden which was based on
the Oleg Krysenkov one.
* The original patch has been reworked by myself.
* Adapted the code to work with the new PluginManager API which
differently than before doesn't need to contact the media_server.

ffmpeg: check against correct version constants.

54.23.x is ffmpeg 0.11, which still has "CodecID" (and x>0).

ffmpeg: detect the library version the right way.

* Fixes the build by detecting the library version using the provided
constants, instead of guessing from the compiler version.

ffmpeg plugin: remove more deprecated functions.

These were all deprecated between releases 0.6 and 0.10 of ffmpeg,
except for one change (renaming of CodecID to AVCodecID) which we can
work around with a typedef. The deprecated functions were still
available in 0.11, but were removed later on after several years of
deprecation.

This makes it possible to build our plugin with any ffmpeg version
between 0.10 and 2.7, so we can now experiment with updating to 2.7 at
least for the gcc4 builds.

* Introduce some currently disabled code to store the AVCodecContext
pointer in the media_format user data section.
* In the AVCodecEncoder, optionally use the AVCodecContext pointer
from the AVFormatWriter instead of its own instance. The problems
I am investigating are not improved by this, but it may be needed
anyway.
* Map the bitrate for audio to a fixed table. Certain encoders will
refuse to use a non-standard bitrate, like the currently enabled
AC-3 encoder.
* Fixed tracing output in _EncodeAudio().

The CodecID for raw-audio actually depends on the sample format
and can't be hard-coded in the EncoderTable.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38464 a95241bf-73f2-0310-859d-f6bbb57e9c96

* synced with ffmpeg-r19678, keeping gcc2 compiler #ifdef we introduced, build only tested on Haiku gcc2
* activated ac3 audio file format support
* uses format metadata to keep the codec context extra data (now needed for flac)

Encoder:
* Fleshed out the Encoder API to support parameter setters/getters and returning
a BView for configuration. (Not yet sure if this is a good idea.)

BMediaTrack:
* Implemented all but one of the unimplemented methods in BMediaTrack. It should
be working as far as that class is concerned, unless I missed some of the
vision. ReplaceFrames() remains a stub, added a comment on why it probably
stays that way.
* Release the Encoder reference in the destructor.

FFmpeg plugin:
* Refactoring to delay opening the AVCodec until encoding the first chunk,
so that we can still adjust parameters.
* Support adjusting parameters via [Set|Get]EncodeParameters(). Currently,
only quality is supported, added TODOs about supporting the bit_rate setup
versus the automatically calculated bit_rate.
* Extended EncoderDescription by a bit_rate scale. The Encoder calculates the
raw bitrate needed by the current media format, and then divides that
number by the specific codec's bit_rate_scale, while taking into account the
desired quality. This seems to work very well already (tested with MPEG4),
although a lot more parameters could be specified for libavcodec, depending
on the desired quality.
* Enabled the ogg muxer in libavformat, although it is currently still disabled
in MuxerTable.cpp, because it rejects unknown codecs. Added TODO to this
effect.

Now supports encoded audio. Added Dolby Digital (AC-3) encoding to test this.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32105 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented audio track encoding. There is something wrong with the PTS
generation for the packets and how I set the time_base in the AVStream and
AVStream->codec structures. This results in the audio streams of the written
files to report a much too long duration.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32064 a95241bf-73f2-0310-859d-f6bbb57e9c96

* 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).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32043 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Let the Encoders use the media_codec_info.sub_id field for their own purposes.
* Implemented some of AVCodecEncoder. Maybe video encoding already works, but
we don't know until the AVFormatWriter is more than just stubs... but I doubt
it. :-)


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32016 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.

Stubbed out implementation of an Encoder and EncoderPlugin. This will probably
need to work differently, such that supported media_formats come into play,
I will know soon when I implement some of the stuff from MediaFormats.h.
