Add AV_PKT_DATA_DISPLAYMATRIX and AV_FRAME_DATA_DISPLAYMATRIX as stream and frame side data (respectively) to describe a display transformation matrix for linear transformation operations on the decoded video. Add functions to easily extract a rotation angle from a matrix and conversely to setup a matrix for a given rotation angle. Signed-off-by: Anton Khirnov <anton@khirnov.net>

This also handles side data properly.

Side data count is incremented by by calling av_packet_new_side_data() in the following loop, setting it explicitly results in the resulting value being twice what it should be. CC: libav-stable@libav.org

All encoders should output proper timestamps now.

Use OutputStream.last_mux_dts as an approximation of 'current' output time instead.

This mirrors the demuxer behaviour and avoids accessing AVCodecContext.codec, which should not be done in muxers.

It is not supposed to be set from outside of libavcodec. Set average framerate instead.

Do not call an AVCodecContext 'stream', that is highly confusing. Also, add a local variable for the current AVStream in the loop over all streams.

Do not leave a non-zero extradata_size set on failure

coded_frame is not meant to be changed from outside of lavc, and is not used for decoding. Set AVCodecContext.field_order instead.

Pad it with the required amount of zeros, check for malloc failure.

Right now, the caller has to manually manage some allocated AVCodecContext fields, like extradata or subtitle_header. This is fragile and prone to leaks, especially if we want to add more such fields in the future. The only reason for this behaviour is so that the AVStream codec context can be reused for decoding. Such reuse is discouraged anyway, so this commit is the first step to deprecating it.

This function should not modify any global state, so there should be no reason for any locking.

Clang Undefined Behaviour Sanitizer seems to make non-constant constant expressions, making the compilation fail when they are used within inline assembly if no optimization is requested. Add -O1 to the cflags to hide the misbehaviour. Bug-Id: 683

avcodec might depend on avresample and with --as-needed required symbols might be get removed if avresample is linked before avcodec. Fixes link failures of avprobe and avplay on aarch64 with --enable-neon-clobber-test.
