Use av_alloc_put_byte() instead of ffio_init_context() since the
latter expects an already allocated AVIOContext.
BeScreenCapture works again, and should fix also #8299.

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: don't use deprecated API in AVCodecDecoder.

* 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().

Fix crash introduced as a last minute change... need to
find a way to do this properly, though. The pixel format
selected by AVCodecEncoder should match here.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39037 a95241bf-73f2-0310-859d-f6bbb57e9c96

* 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.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39035 a95241bf-73f2-0310-859d-f6bbb57e9c96

* 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.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38851 a95241bf-73f2-0310-859d-f6bbb57e9c96

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

Disabled tracing.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34930 a95241bf-73f2-0310-859d-f6bbb57e9c96

Don't call avcodec_close() on an unopened codec, as that causes a crash.
Happens for example when you create a BMediaFile and close it without
committing the header


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33845 a95241bf-73f2-0310-859d-f6bbb57e9c96

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

* AVWriter::StreamCookie::~StreamCookie() incorrectly freed packet data that it
didn't own.
* We are supposed to open the AVCodecContext in the writer, even though we never
use it. According to libav-users mailing list, this is necessary, since that
will allocate and initialize some structures that are later needed in
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
and which we don't.
* Use more sensible defaults for the stream bitrate, so that we get better
quality video by default. This and other parameters can be calculated when
we implement setting the quality.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32103 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

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... :-)
