Bug-Id: CID 1308152

The old one is the result of the reverse engineering and guesswork.
The new one has been written following the now-available specification.

This work is part of Outreach Program for Women Summer 2014 activities
for the Libav project.

The fate references had to be changed because the old demuxer truncates
the last frame in some cases, the new one handles it properly.
The seek-test reference is changed because seeking works differently
in the new demuxer. When seeking, the packet is not read from the stream
directly, but it is rather constructed by the demuxer. That is why
position is -1 now in the reference.

Since it's truncated, the result depends on how specifically the demuxer
and the decoder handle errors.

Since it's truncated, the result depends on how specifically the demuxer

Should fix a large number of possible races with frame threading.

Fixes possible invalid reads, once one of those refs is freed, but the
others remain.

We still want to flush the filters on EOF and possibly apply streamcopy.

This also ensures this is always done, avoiding infinite loops if an
error occurs at the end of the input.

Any other x265 symbol may not exported, e.g. if the build is a
multilib (10-bit and 8-bit in one) build.

This is the only symbol we directly call, and is available in the
build number we check for.

Fixes the configure check on multilib x265 builds.

Using the internal DXTC routines brings support for non multiple of 4
textures. A new test is added to cover this feature. Hashes differ
since the decoding algorithm is different, though no visual changes
have been spotted.

The default value for unset is -1, not 0.

Problem introduced in 66028b7b

Bump the minimum libvpx version to 1.3.0 and rework the configure logic
to fail only if no decoders and encoders are found.

14496-3 suggests packing main_data of MP3 that is usually scattered
into multiple frames due to bit reservoir.

However, after packing main_data into a access unit, bitrate index
in the MPEG audio frame header doesn't match with actual frame size.

In order to accept this, this patch removes unnecessary frame size
checking on mp3 decoder.

Also, mov demuxer was changed to use MP3 parser only on special cases
(QT MOV with specific sample description) to avoid re-packetizing.

Also use the frame pixel format instead of the one from the codec
context, which is more robust.

The AVCodecContext width, height, coded_width, coded_height and format
are used mainly as decoding hints and they get internally overwritten
during the data parsing stage.

Do not assume they match the last AVFrame provided by
avcodec_decode_video2 and assimilated functions since multi-threading
and other frame reordering might make those values to refer to frames
that will be outputted in the future.

GNUTLS_SHUT_RDWR means GnuTLS will keep waiting for the server's
termination reply. But since we don't shutdown the TCP connection at
this point yet, GnuTLS will just keep skipping actual data from the
server, which basically is perceived as hang.

Use GNUTLS_SHUT_WR instead, which doesn't have this problem.

of type 'double' but has parameter of type 'float' which may cause
truncation of value [-Wabsolute-value]".
