Anton Khirnov	632ad2248e	lavc: Add an internal wrapper around get_format() It will be useful in the following commits.	11 years ago
Carl Eugen Hoyos	ced0d6c14d	Use correct msvc type specifiers for ptrdiff_t and size_t. The Windows runtime aborts if it finds %t or %z. Fixes ticket #3472. Reviewed-by: Ronald Bultje	11 years ago
Michael Niedermayer	375013e3d6	avcodec/mpeg12dec: drop confusing av_dlog() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
wm4	f6774f905f	mpegvideo: operate with pointers to AVFrames instead of whole structs The most interesting parts are initialization in ff_MPV_common_init() and uninitialization in ff_MPV_common_end(). ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL checks for Picture.f, because these functions can be called on uninitialized or partially initialized Pictures. NULL pointer checks are added to ff_thread_release_buffer() stub function. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	11 years ago

Janne Grunau	73eca738ac	mpeg12dec: do not add stereo3D side data to a non-existing frame User data is usually coded before slice data. That means the frame the user data belongs to is not available while parsing the user data. The stereo3D side data has to use the same indirection over the private context as pan scan information and A53 captions. Bug-Id:632	11 years ago

Michael Niedermayer	7667afffb8	avcodec/mpeg12dec: Revert Change to mpeg2_fast_decode_block_non_intra This fixes the speed regression from `20626f53e9` and still checks sufficiently to prevent out of allocated memory accesses due to the index Before: 1823 decicycles in mpeg2_fast_decode_block_non_intra, 8388493 runs, 115 skips After: 1808 decicycles in mpeg2_fast_decode_block_non_intra, 8388494 runs, 114 skips Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	6a92598e14	avcodec/mpeg12dec: Redesign index checks for mpeg2_fast_decode_block_intra This fixes the speed regression from `20626f53e9` and still checks sufficiently to prevent out of allocated memory accesses due to the index Before: 1681 decicycles in mpeg2_fast_decode_block_intra, 4194238 runs, 66 skips After: 1658 decicycles in mpeg2_fast_decode_block_intra, 4194248 runs, 56 skips Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Janne Grunau	6d93307f8d	mpeg12: check scantable indices in all decode_block functions Add checks to the fast functions used with CODEC_FLAGS2_FAST and move the check for all other functions to before the invalid memory is accessed.

Diego Biurrun	19e30a58fc	Deprecate obsolete XvMC hardware decoding support XvMC has long ago been superseded by newer acceleration APIs, such as VDPAU, and few downstreams still support it. Furthermore XvMC is not implemented within the hwaccel framework, but requires its own specific code in the MPEG-1/2 decoder, which is a maintenance burden.	11 years ago
