Vittorio Giovara	d66e305bd1	er: move relevant fields from Picture to ERPicture This is done to disentangle ER from mpegvideo.

Please note that buffers need to be allocated before calling ff_er_frame_end().	11 years ago

Janne Grunau	f795a8a8bf	h264: make context_count unsigned Removes the bogus but scary looking warning 'libavcodec/h264.c:4529:49: warning: array subscript is below array bounds [-Warray-bounds]'.	11 years ago

Michael Niedermayer	8a3b85f3a7	avcodec/h264: update current_sps & sps->new only after the whole slice header decoder and init code finished This avoids them being cleared before the full initialization finished Fixes out of array read Fixes: asan_heap-oob_f0c5e6_7071_cov_1605985132_mov_h264_aac__Demo_FlagOfOurFathers.mov Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	e708424b70	avcodec/h264: Disallow pps_id changing between slices Such changes are forbidden in H.264 and lead to race conditions Fixes out of array read Fixes: signal_sigsegv_f9796a_1613_cov_3114610371_FM1_BT_B.h264 Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Janne Grunau	ea49f60523	h264: skip chroma edges at the picture boundary while deblocking 4:4:4 This handles macroblock edges for the chroma components in the same way as for the luma compoment for 4:4:4 streams.

Anton Khirnov	7f0e81db3c	h264: limit allowed pred modes in ff_h264_check_intra_pred_mode() to 3 Higher modes are not allowed for 16x16/chroma, which is what this function is used for. Otherwise this function would return 0 (vertical prediction) for invalid higher modes, which could result in invalid reads.
