| * dvbsubdec: Fixed segfault when decoding subtitlesLorenz Brun2017-06-28
| | | | | | | | | | | | | | | | | | | | This fixes a segfault (originally found in Movian, but traced to libav) when decoding subtitles because only an array of rects is allocated, but not the actual structs it contains. The issue was probably introduced in commit 2383323 where the loop to allocate the rects in the array was thrown away. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

| * lavc: Add data and linesize to AVSubtitleRectVittorio Giovara2015-10-21
| | | | | | | | | | | | | | | | | | | | | | | | Use the new fields directly instead of the ones from AVPicture. This removes a layer of indirection which serves no pratical purpose whatsoever, and will help in removing AVPicture structure completely later. Every subtitle encoder/decoder seamlessly points to the new arrays, so it is possible to deprecate AVSubtitleRect.pict. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
