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 declarative macro with version and name

* Namespaces protect symbols, I didn't consider that when adding
the BCodecKit namespace, so, the AddOnManager complained that
instantiate_plugin() was missing. A macro is introduced that allow
plugins to specify it's className, version and name, this ease
the declaration of the plugin symbols, otherwise the function
should have been declared inside the BCodecKit namespace which
we would like to avoid.
* The code is also more future proof, since in future the AddOn manager
can begin to check for plugin versions.

ffmpeg: Update class names

add-ons/media/ffmpeg: Remove global initializer system.

All of the functions it calls are deprecated and no longer needed,
as FFmpeg loads all codecs automatically now, and uses pthreads internally
for locking as needed.

ffmpeg: Remove obsolete code

ffmpeg: implement deinterlace feature for ffmpeg 3.x.

* Use the yadif filter.
* Fixes #12731.

FFmpegPlugin: Remove forgot variable

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 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.

Enabled any and all decoders and demuxers which are currently compiled into
FFmpeg. It's a bit sad, but this obsoletes pretty much all other decoder
and reader plugins. Some of them were built on external libraries as well
(AC3 (not part of default image anyway, since it's GPL), APE, MusePack),
so it's not really a big difference to using FFmpeg as external library.
The format matching is greatly simplified by using B_MISC_FORMAT_FAMILY
for everything but raw audio, and the actual FFmpeg CodecID as codec tag.
The downside of this is that the AVFormatReader can no longer be used with
other decoder plugins, but it would be easy to add special cases for native
decoders we wish to support. Obviously the out of the box support for file
formats and decoders has greatly increased with this change, so there has
to be a pretty good reason now for writing a "native" decoder or reader.

Apparantly, FFmpeg has lock management now, and from the tracing, it is indeed
used. Spotted this on the libav*-user mailing list.

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.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32124 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

Implemented support for get_next_encoder() variations from MediaFormats.h.
The AddOnManager in the media_server registers one encoder entry per
successful EncoderPlugin::RegisterNextEncoder(). This gives us a first idea
what media_format_family and input/output media_type is supported. The
mechanism may have to be extended, or the Encoder needs an API to specialize
a format further. In that case, the get_next_encoder() version that takes
optional _acceptedInput/OutputFormat needs to instantiate the plugin and
needs to ask the Encoder. But AFAIK, no app uses it like that anyway.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32005 a95241bf-73f2-0310-859d-f6bbb57e9c96

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.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31994 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... :-)


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31956 a95241bf-73f2-0310-859d-f6bbb57e9c96

* It actually helps a lot to turn on all the demuxers if you want to use any.
* The URLProtocol idea seems not to work out, so I removed that code, but
the other idea of setting up a ByteIOContext actually works, once I seek
back to the beginning of the stream after reading the initial probe buffer,
we may also offset the buffer pointer in the ByteIOContext to where we
have already read, but I am not sure of possible side effects of that.

We can now probe for the correct demuxer and detect streams.

Work in Progress of trying to get libavformat to detect anything...
unsuccessful so far.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31369 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Use a static global object to initialize libavformat and libavcodec.
* Turn off tracing in the AVCodecDecoder which I accidentally turned on in
a previous commit.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31366 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Renamed avcodec folder to ffmpeg.
* Cleaned up plugins Jamfile.
