Vittorio Giovara	a594f17f83	dvbsubdec: Free subrect memory on allocation error Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	7 years ago
Lorenz Brun	1cfd566324	dvbsubdec: Fixed segfault when decoding subtitles 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>	7 years ago

Vittorio Giovara	a17a766190	lavc: Add data and linesize to AVSubtitleRect 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>	9 years ago
