Michael Niedermayer	cfce6f7efd	avcodec/mpegvideo: Set err on failure in ff_mpv_common_frame_size_change() Found-by: ubitux Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	0d0f7f0ba4	avcodec/mpegvideo: check that the context is initialized in ff_mpv_common_frame_size_change() The function otherwise would initialize the context without setting context_initialized alternatively we could set context_initialized Fixes valgrind anomalies related to ticket 3928 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	2762323c37	avcodec/mpegvideo: Use "goto fail" for all error paths in ff_mpv_common_frame_size_change() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

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).

Michael Niedermayer	c5fc8ae126	avcodec/mpegvideo: fix edge emulation with uvlinesize below 25 Fixes fate-vsynth3-wmv2 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
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

Carl Eugen Hoyos	941b2240f2	Do not overwrite VDPAU structures in ff_MPV_frame_start(). Fixes crashes with VDR and MPlayer as reported by irc user crow.	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
