Carl Eugen Hoyos	712ef25116	Avoid a null pointer dereference after oom on frame size change in mpegvideo.c. Fixes ticket #2735.	12 years ago
Michael Niedermayer	0abe923d20	mpegvideo: fix forgotten lowres op_index limits Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	c2625c26c5	mpegvideo: implement ff_put_h264_chroma_mc1 & ff_avg_h264_chroma_mc2 These are needed for lowres 3 This may fix Ticket2538 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	5f44f47b72	mpegvideo_enc: do not unreference frames before the code is done with them Fixes Ticket2592 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Janne Grunau	3eae9b030c	mpegvideo: unref buffers in ff_mpeg_unref_picture on frame size changes ff_mpeg_unref_picture clears the flag indicating that the frame needs to be reallocated after a frame size change. Since we have now reference counted buffers we can unref the buffers immediately.	12 years ago
Janne Grunau	4b79668154	mpegvideo: unref old current_picture before allocating a new one Allows decoding with only three frame buffers with frame reference counting. Fixes VAAPI based decoding in vlc which uses only three frame buffers for the mpegvideo-based codecs.	12 years ago
Jindrich Makovicka	259af1b923	mpegvideo: allocate sufficiently large scratch buffer for interlaced vid MPV_decode_mb_internal needs 3 * 16 * linesize bytes of scratch buffer For interlaced content, linesize is multiplied by two after the allocation of the scratch buffer, and the dest_cr pointer ends past the buffer. This patch makes ff_mpv_frame_size_alloc allocate a total of (aligned line_size) * 2 * 16 * 3 bytes, which suffices even for the interlaced case.

Michael Niedermayer	4824aea7af	avcodec/mpegvideo: change asserts to av_asserts Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Ronald S. Bultje	f4fed5a2f9	mpegvideo: Use hpeldsp instead of dsputil for half-pel functions This also converts vc1, since that is mpegvideo-based. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	6ae03353de	mpegvideo: Make the table reallocation more robust. This fixes out of array writes after resolution changes No FFmpeg releases are known to be affected by this Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Michael Niedermayer	7b3ca7ae8b	mpegvideo/h264: drop period_since_free This should not be needed anymore Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Martin Storsjö	75644335b9	lavc: Move start code finding to utils.c This allows dropping the mpegvideo dependency from a number of components. This also fixes standalone building of the h264 parser, which was broken in `64e438697`. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Hendrik Leppkes	c3ebfcd6e1	mpegvideo: allocate hwaccel privdata after the frame buffer This ensures the hwaccel privdata does not leak when a frame buffer could not be allocated (and toggle the assert when the frame is re-used). Having no frame buffer available is quite common when using the DXVA2 hwaccel in situations where the DXVA2 renderer is being re-allocated, for example when moving between displays.

Michael Niedermayer	ee3c3dd523	ff_alloc_picture: free tables in case of dimension mismatches Fixes memory corruption In theory this should not be needed but its better to check at one place than to hope 50 other places set the flags correctly	12 years ago

Anton Khirnov	19cac8e301	mpegvideo: remove useless references to h264 and svq3 The h264 decoder does not use mpegvideo anymore. The svq3 decoder only uses ff_draw_horiz_band().	12 years ago
Anton Khirnov	37045e4229	mpegvideo: drop vismv code It has been broken for over a year without anyone complaining or noticing, thus proving that nobody ever uses it.	12 years ago
Anton Khirnov	759001c534	lavc decoders: work with refcounted frames.	12 years ago
Anton Khirnov	ad0c9f2d5d	lavc: move AVFrame.hwaccel_picture_private to Picture. This field is private and should not be present in a public struct. It is only used in DXVA with mpegvideo-based decoders currently.	12 years ago
Martin Storsjö	d88738e403	mpegvideo: Conditionally build error_resilience bits This breaks the dependency of mpegvideo on error_resilience allowing compilation of components that depend on the former w/o the latter.	12 years ago
Ronald S. Bultje	8d061989dd	lavc: Split out ff_hwaccel_pixfmt_list_420[] over individual codecs Not all hwaccels implement all codecs, so using one single list for multiple such codecs means some codecs will be represented in the list, even though they don't actually handle that codec. Copying specific lists in each codec fixes that. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
