Michael Niedermayer	5b73ba9887	avcodec/mpeg12dec: Add FF_CODEC_CAP_SKIP_FRAME_FILL_PARAM This decreases the amount of computations and memory needed for analysing mpeg1/2 streams the properties update is moved from code that is skiped if skip_frame is set to code that is not skiped so the change doesnt loose that from being executed Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	8 years ago

Ganesh Ajjanagadde	2cbaa078d1	avcodec: use HAVE_THREADS header guards to silence -Wunused-function When compiled with --disable-pthreads, e.g http://fate.ffmpeg.org/report.cgi?time=20150917015044&slot=alpha-debian-qemu-gcc-4.7, a bunch of -Wunused-functions are reported due to missing header guards around threading related functions.

Gwenole Beauchesne	9f8e57efe4	vaapi: define a unique pixel format for VA-API (AV_PIX_FMT_VAAPI). Deprecate older VA pixel formats (MOCO, IDCT) as it is now very unlikely to ever be useful in the future. Only keep plain AV_PIX_FMT_VAAPI format that is aliased to the older VLD variant.

wm4	94c0df79c7	lavc: propagate hwaccel errors At least the new videotoolbox decoder does not actually set a frame if end_frame fails. This causes the API to return success and signals that a picture was decoded, even though AVFrame->data[0] is NULL. Fix this by propagating end_frame errors.	10 years ago

Philip Langdale	9ae766d1c6	avcodec/vdpau: Re-factor pre-hwaccel helper functions into separate header h264.h and hevc.h are mutually exclusive due to defining some of the same names. As such, we need to avoid forcing h264.h to be included if we want hevc decode acceleration to be possible. However, some of the pre-hwaccel helper functions need h264.h. To avoid messy collisions, let's move the declaration of all those helpers to a separate header which we will exclude for the hevc support (which will be hwaccel-only).
