2017-03-03Revert "avutil/frame: Disallow zero sized frame side data"Michael Niedermayer
Found a case where we use size==0, the other related commits remain needed, and should be sufficient to fix the original issue This reverts commit 7e4f32f4e4b93c95dcc872cb844c5548e69f352e. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

2017-02-26avutil/frame: Reimplement av_frame_new_side_data() without size=0 special caseMichael Niedermayer
The size 0 special case causes side data to be created which is different and a special case if for any reasons size = 0 is passed Fixes: multiple runtime error: null pointer passed as argument 1, which is declared to never be null Fixes: 653/clusterfuzz-testcase-5773837415219200 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/targets/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
2017-02-13AVFrame: add an opaque_ref fieldwm4
This is an extended version of the AVFrame.opaque field, which can be used to attach arbitrary user information to an AVFrame. The usefulness of the opaque field is rather limited, because it can store only up to 32 bits of information (or 64 bit on 64 bit systems). It's not possible to set this field to a memory allocation, because there is no way to deallocate it correctly. The opaque_ref field circumvents this by letting the user set an AVBuffer, which makes the user data refcounted. Signed-off-by: Anton Khirnov <anton@khirnov.net> Merges Libav commit 04f3bd349651.

2016-06-21lavc: export the timestamps when decoding in AVFrame.ptsAnton Khirnov
Currently it's exported as AVFrame.pkt_pts, which is also the only use for that field. The reason it is done like this is that lavc used to export various codec-specific "timing" information in AVFrame.pts, which is not done anymore. Since it is confusing to the callers to have a separate field which is used only for decoder timestamps and nothing else, deprecate pkt_pts and use just AVFrame.pts everywhere.

These field are difficult to interpret, and are provided by a single encoder (mpegvideoenc). In general they do not belong to a structure containing raw data only, so remove them from AVFrame.

2014-08-18avcodec: export motion vectors in frame side data on demandClément Bœsch
The reasoning behind this addition is that various third party applications are interested in getting some motion information out of a video "for free" when it is available. It was considered to export other information as well (such as the intra information about the block, or the quantization) but the structure might have ended up into a half full-generic, half full of codec specific cruft. If more information is necessary, it should either be added in the "flags" field of the AVMotionVector structure, or in another side-data. This commit also includes an example exporting them in a CSV stream.
