2016-12-07lavc: Add spherical packet side data APIVittorio Giovara
Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
2016-11-20avcodec/avpacket: fix leak on realloc in av_packet_add_side_data()James Almer
If realloc fails, the pointer is overwritten and the previously allocated buffer is leaked, which goes against the expected behavior of keeping the packet unchanged in case of error. Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: James Almer <jamrial@gmail.com>

2016-02-26avpacket: properly reset data/size in av_packet_move_ref()Anton Khirnov
It currently just calls av_init_packet(), which does not touch those fields.
2016-02-25libavcodec:add packet level support for mastering metadataNeil Birkbeck
Some containers, like webm/mkv, will contain this mastering metadata. This is analogous to the way 3D fpa data is handled (in frame and packet side data). Signed-off-by: Neil Birkbeck <neil.birkbeck@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
2016-02-23lavc/lavf: transmit stream_id information for mpegts KLV data packetsStefano Sabatini
This allows to copy information related to the stream ID from the demuxer to the muxer, thus allowing for example to retain information related to synchronous and asynchronous KLV data packets. This information is used in the muxer when remuxing to distinguish the two kind of packets (if the information is lacking, data packets are considered synchronous). The fate reference changes are due to the use of av_packet_merge_side_data(), which increases the size of the output packet size, since side data is merged into the packet data.

2015-10-26avpacket: Deprecate av_dup_packetLuca Barbato
As documented, `av_dup_packet` is broken by design, `av_packet_ref` matches the AVFrame ref-counted API and can be safely used instead.

Note that convergence_duration had another meaning, one which was in practice never used. The only real use for it was a 64 bit replacement for the duration field. It's better just to make duration 64 bits, and to get rid of it. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

2013-11-21avcodec: move end zeroing code from av_packet_split_side_data() to ↵Michael Niedermayer
avcodec_decode_subtitle2() This code changes the input packet, which is read only and can in rare circumstances lead to decoder errors. (i run into one of these in the audio decoder, which corrupted the packet during av_find_stream_info() so that actual decoding that single packet failed later) Until a better fix is implemented, this commit limits the problem. A better fix might be to make the subtitle decoders not depend on data[size] = 0 or to copy their input when this is not the case.
