Vittorio Giovara	3496cec433	msrle: Use AVFrame instead of AVPicture Callers always use a frame and cast it to AVPicture, change ff_msrle_decode() to accept an AVFrame directly instead. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Luca Barbato	5ecabd3c54	msrle: Use FFABS to determine the frame size in msrle_decode_pal4 As done in msrle_decode_8_16_24_32. Bug-Id: CVE-2015-3395 CC: libav-stable@libav.org	10 years ago
Michael Niedermayer	50d878d930	avcodec/msrledec: Ask for sample that uses a branch with a unused byte Finding out if this is correct or buggy is easiest with a sample Fixes: CID1297620 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Andreas Cadhalpun	ae6fd7300b	msrledec: use signed pixel_ptr in msrle_decode_pal4 This fixes segmentation faults, when pic->linesize[0] is negative. In that case 'line * pic->linesize[0] + pixel_ptr' is treated as unsigned and wraps around. This reverts commit `7d78a964`. The problem was introduced in commit `f7e1367f`, which should obsolete that commit.
