Clément Bœsch	f888331769	avfilter: add codecview filter	10 years ago
Clément Bœsch	b0352b1997	avcodec: export motion vectors in frame side data on demand The reasoning behind this addition is that various third party applications are interested in getting some motion information out of a video "for free" when it is available. It was considered to export other information as well (such as the intra information about the block, or the quantization) but the structure might have ended up into a half full-generic, half full of codec specific cruft. If more information is necessary, it should either be added in the "flags" field of the AVMotionVector structure, or in another side-data. This commit also includes an example exporting them in a CSV stream.	11 years ago

John Stebbins	998c9f15d1	idct: remove call to ff_idctdsp_init from ff_MPV_common_init One step in untangling the mpegvideo code and fixing some problems in the order that initialization is being done in h263dec and h261dec.	11 years ago
James Yu	16e6652286	aarch64: NEON intrinsics dct_unquantize_h263. Intrinsics only used on aarch64 since the existing ARMv7 NEON asm is slightly faster (Cortex-A9, gcc-4.8, micro-benchmarks and full decoding time).

Janne Grunau	0ddc53dabb	mpegvideo: synchronize AVFrame pointers in ERContext fully Since error resilience uses AVFrame pointers instead of references it has to copy NULL pointers too. After a codec flush the last/next frame pointers in MpegEncContext are NULL and the old pointers remaining in ERContext are invalid. Fixes a crash in vlc for android thumbnailer. Reported and debugged by Adrien Maglo <magsoft@videolan.org>.	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

Vittorio Giovara	d66e305bd1	er: move relevant fields from Picture to ERPicture This is done to disentangle ER from mpegvideo. In order to use a classic Picture, callers can use ff_mpeg_set_erpic() or use a custom function to set the fields. Please note that buffers need to be allocated before calling ff_er_frame_end().	11 years ago

Janne Grunau	fb0c9d41d6	avutil: remove timer.h include from internal.h Added libavutil/timer.h include to all files with {START,STOP}_TIMER.	11 years ago
Anton Khirnov	024db24912	mpegvideo: allocate edges when encoding. Allocating edges will be removed from generic code, so the encoder must handle this explicitly.	11 years ago
Anton Khirnov	ebfe622bb1	mpegvideo: drop support for real (non-emulated) edges Several decoders disable those anyway and they are not measurably faster on x86. They might be somewhat faster on other platforms due to missing emu edge SIMD, but the gain is not large enough (and those decoders relevant enough) to justify the added complexity.	11 years ago
Michael Niedermayer	950fb8acb4	avcodec/mpegvideo: fix ac/dc_val and coded_block table sizes With interlaced vc1 it was possible that accesses could happen outside these tables before this. Regression since `017e234c20` Reproduced with a sample from Mateusz "j00ru" Jurczyk and Gynvael Coldwind Fixes (again) : 480i30__codec_WVC1__mode_2__framerate_29.970__type_2__preproc_17.SIGFPE.bfa.390.wmv No releases are affected by this Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Anton Khirnov	aec25b1c46	mpegvideo: split the encoding-only parts of frame_start() into a separate function This introduces some code duplication. However, much of it should go away once the decoders stop using MpegEncContext.	11 years ago
Anton Khirnov	feded990e3	mpegvideo: set reference/pict_type on generated reference frames Otherwise the generic code will unref them, which can then result in last_picture_ptr == current_picture_ptr, which causes deadlocks at least in rv40.
