Andreas Rheinhardt	2ec62b1ca6	avcodec/pthread_frame: Use RefStruct API for ThreadFrame.progress Avoids allocations and error checks and allows to remove cleanup code for earlier allocations. Also avoids casts and indirections. Reviewed-by: Anton Khirnov <anton@khirnov.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	1 year ago
Andreas Rheinhardt	5d63bd5b9c	avcodec/h264dec: Move inline functions only used by CABAC/CAVLC code Most of the inline functions in h264dec.h are only used by h264_cavlc.c and h264_cabac.c. Therefore move them to the common header for these two, namely h264_mvpred.h. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	1 year ago
Andreas Rheinhardt	b3551b6072	avcodec/thread: Move ff_thread_(await\|report)_progress to new header This is in preparation for further commits that will stop using ThreadFrame for frame-threaded codecs that don't use ff_thread_(await\|report)_progress(); the API for those codecs having inter-frame depdendencies will live in threadframe.h.

Anton Mitrofanov	06dda70f1e	avcodec/h264_mb: Fix 8x8dct in lossless for new versions of x264 Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	8 years ago
Anton Khirnov	f638b67e57	h264: move the parameter set definitions to a new header file The PS parsing code is independent from the decoder, so it makes more sense for it to have its own separate header.	9 years ago
Anton Khirnov	9df889a5f1	h264: rename h264.[ch] to h264dec.[ch] This is more consistent with the naming of other decoders.	9 years ago

Anton Khirnov	3176217c60	h264: decouple h264_ps from the h264 decoder Make the SPS/PPS parsing independent of the H264Context, to allow decoupling the parser from the decoder. The change is modelled after the one done earlier for HEVC. Move the dequant buffers to the PPS to avoid complex checks whether they changed and an expensive copy for frame threads.	9 years ago

Anton Khirnov	e481458bc3	h264: factor out pred weight table parsing into a separate file This will allow decoupling the parser from the decoder.	9 years ago

Michael Niedermayer	60e7d2d7b9	avcodec/h264_mb: assert that frame waiting code actually references 2 fields/1 frame Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Anton Khirnov	c28ed1d743	h264: move [uv]linesize to the per-slice context While it is a per-frame variable, it is only really used in the low-level decoding code, so it is more efficient to store it in the slice context.	10 years ago
Anton Khirnov	a12d3188cb	h264: use a smaller struct for the ref lists There is no need to store a whole H264Picture, with a full AVFrame embedded in it. This should allow getting rid of the embedded AVFrame later.	10 years ago
Anton Khirnov	94295106d2	h264_mb: remove an unused function parameter	10 years ago
Anton Khirnov	c377e04d8a	h264: move top_borders into the per-slice context Also change the method for allocating to the same one as used by edge_emu_buffer.	10 years ago
Anton Khirnov	36d04801ba	h264: move the scratch buffers into the per-slice context Also change the method for allocating them. Instead of two possible alloc calls from different places, just ensure they are allocated at the start of each slice. This should be simpler and less bug-prone than the previous method.	10 years ago

Reimar Döffinger	33fc1ccb49	h264_mb: Use smaller data type for refs in await_references. As far as I can tell the value can never go outside the int16_t type. And especially the cost of the initialization is reduced quite a bit by making it smaller. Overall decoding speedup not measurable though.
