ffmpeg: fix missing initialization of AVFrame

ffmpeg API reference does not allow to allocate AVFrame on the stack,
and especially not without initializing anything in the frame. Calling
av_frame_unref then attempts to free some non-existing data, and
crashes.

we can reuse here.

ffmpeg: leak when re-allocating ffmpeg context

The _Setup method can be called several times if the parameters are
changed (for example when calling SetQuality). But it always allocated a
new context without freeinthe previous one, resulting in a leak.

Part of #9458, it fixes the largest leak there (10K bytes for each loop
of the provided test) but there are other leaks left as well, some of
which apparently need an update to a newer ffmpeg version removing some
deprecated fields.

ffmpeg: improve context allocation

The context can be better allocated if it knows which codec it will be
used with (preallocating things with the correct size). To do this we
need to delay allocation from the constructor to the Init method.

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.

ffmpeg encoder: do not use deprecatred function

Replace avcodec_encode_audio with avcodec_encode_audio2. The latter
provides us with more information on the encoded data, so we can avoid
guessing things on our own. It also handles memory allocations on its
own, which fix some cases where we would provide a too small buffer.

ffmpeg plugin: improve encoding format negociation

The ffmpeg encoders are restricted on which raw formats they accept
(each with different constraints). When asked to encode something, the
ffmpeg encoder now checks the codec capabilities and if the suggested
input format does not match, modifies it to something the codec can
actually handle.

Enable "experimental" codecs, as this is needed for AAC support in ffmpeg 0.10.

This allows format negociation to work properly, and as a result we can
enable several new audio formats: AAC (for MPEG family only), AC3, and
raw audio. Declare MKV as B_ANY_FORMAT_FAMILY since it is designed to be
a generic container (so it is possible to put AAC in MKV). Also remove
duplicate entries for AC3.

ffmpeg plugin: update to 0.11.5.

Revert "ffmpeg: switch to 0.11.1" (hrev44483)

This reverts commit 14b654326dc9c4b4ff38811672eb53e6723eece3.

Unfortunately that changeset causes a regression on GCC 2, which
makes playback of (some?) video impossible. This is due to Libavcodec
being miscompiled, which requires gcc >= 4.2

Resolves the regression of #8856, but does not fix the root issue.

ffmpeg: switch to 0.11.1

ffmpeg: updated gcc2 package and fixed crashes on exit.

* replaced calls to free() with calls to av_free().
* updated gcc2 package to disable SSE and a few options like we had
before with 0.6.

* 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().

number by the specific codec's bit_rate_scale, while taking into account the

although a lot more parameters could be specified for libavcodec, depending

* We are supposed to open the AVCodecContext in the writer, even though we never

av_write_header(). How this is supposed to work for encoders that libavcodec
does not support, or which we don't know how to map, I do not yet know. For
now it doesn't matter and resolves the problem that audio tracks report the
wrong stream duration.
* Some more improvements with regards to what information we need to fill out

quality video by default. This and other parameters can be calculated when
we implement setting the quality.

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.

* 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.

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).

* 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. :-)

* 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.
