Anton Khirnov	440e8dd374	h264: drop a comment that carries no useful information	10 years ago
Anton Khirnov	11f024ef0a	h264: move freeing the escaped RBSP buffer to free_context() It does not logically belong in free_tables(), since it's not allocated in alloc_tables() and its size has nothing to do with the frame size.	10 years ago
Anton Khirnov	ee62b364be	h264: eliminate ff_h264_set_parameter_from_sps() That function currently does two things -- reinitializing the DSP contexts and setting low_delay based on the SPS values. The former more appropriately belongs in h264_slice_header_init(), while the latter only really makes sense in decode_slice_header(). The third call to ff_h264_set_parameter_from_sps(), done immediately after parsing a new SPS, appears to serve no useful purpose, so it is just dropped. Also, drop now unneeded H264Context.cur_chroma_format_idc.	10 years ago
Anton Khirnov	a6cd154463	h264: move the DPB init/uninit to init_context()/free_context() Currently, the DPB is initialized in alloc_tables() and uninitialized in free_tables(), but those functions manage frame size-dependent variables, so DPB management does not logically belong in there. Since we want the init/uninit to happen exactly once per the context lifetime, init_context()/free_context() are the proper place for this code.	10 years ago
Anton Khirnov	9d33bab583	h264: drop H264Context.ouputed_poc It is only set, but never used for anything.	10 years ago
Anton Khirnov	27b0e6ebfd	h264: drop needs_realloc It is not needed anymore since switching to refcounted frames.	10 years ago
Vittorio Giovara	6a85dfc830	lavc: Replace av_dlog and tprintf with internal macros	10 years ago
Anton Khirnov	bd737b5178	h264: reset the private data in init_thread_copy() The generic code copies the main context's private data to all the others. However that is quite dangerous, as it might end up copying some pointers that are or will become invalid. Since everything we actually need will be copied later in update_thread_context(), it's safest to zero the private data in init_thread_copy(), so it works the same way as init for the main context.	10 years ago
Anton Khirnov	a939e5b252	h264: remove a commented out nonsense line	10 years ago
Anton Khirnov	65afa65e73	h264: drop redundant initialization of the scaling matrices It will always be initialized when actually parsing the PPS.	10 years ago
Anton Khirnov	e1f907711a	h264: factor out common code from init() and init_thread_copy()	10 years ago
Anton Khirnov	43fd3dd80c	h264: drop redundant initialization in init() There is no real advantage to initializing any of those in init, assuming yuv420, before the real stream parameters are known.	10 years ago
Anton Khirnov	050324d020	h264: initialize cur_chroma_format_idc This makes sure the various DSP contexts get properly initialized in ff_h264_set_parameter_from_sps() whatever the value of raw_bits_per_sample.	10 years ago
Anton Khirnov	a4d34e218f	h264: disable ER by default The way it is currently designed is fundamentally unsafe and cannot be reasonably fixed without completely rewriting it.	10 years ago
Anton Khirnov	2b4c38d3c6	h264: drop some mpegvideo remnants from draw_horiz_band() This code makes no sense for h.264.	10 years ago
Anton Khirnov	5bf3c0fa49	h264: drop the now unused per-slice H264Contexts	10 years ago
Anton Khirnov	51d8725a6e	h264: use the main H264Context as the parent for all slice contexts There is now no need to have per-slice copies of the H264Context.	10 years ago
Anton Khirnov	3178f4d33f	h264: move rbsp_buffer into the per-slice context	10 years ago
Anton Khirnov	582683b6ac	h264: move remaining ER stuff into the per-slice context	10 years ago
Anton Khirnov	5bc69f38c1	error_resilience: do not require mbintra/skip tables h264dec does not use them at all and only allocates them for ER.	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
Anton Khirnov	5c4b98de4d	h264.c: constify all uses of H264Context in slice and lower-level functions All the variables modified by this code are either per-MB arrays or have been moved to the per-slice context	10 years ago
Anton Khirnov	f42485dbce	h264: use a separate GetBitContext for slice data	10 years ago
Anton Khirnov	2ea00e35e4	h264: do not abuse the context as a temporary storage in get_last_needed_nal() Use a local variable instead.	10 years ago
Anton Khirnov	404a416d4b	h264: remove some remnants of data partitioning	10 years ago

Anton Khirnov	92c6c2a605	h264: split weighted pred-related vars into per-slice context	10 years ago
Anton Khirnov	a06b0b1295	h264: initialize H264Context.avctx in init_thread_copy This prevents using a wrong (first thread's) AVCodecContext if decoding a frame in the first pass over all threads fails.	10 years ago
Michael Niedermayer	61928b68dc	h264: Do not share rbsp_buffer across threads Signed-off-by: Luca Barbato <lu_zero@gentoo.org> CC: libav-stable@libav.org	10 years ago
Anton Khirnov	167e004e1a	h264: drop any pretense of support for data partitioning It does not work correctly and apparently never did. There is no indication that this (mis)feature is ever used in the wild or even that any software other than the reference supports it. Since the code that attempts to support it adds some nontrivial complexity and has resulted in several bugs in the past, it is better to just drop it.	10 years ago
Anton Khirnov	ecab21ac47	h264: do not reset the ref lists in flush_change() They are always constructed anew when needed, so there is no need to reset them explicitly.	10 years ago
Anton Khirnov	9404a47a2d	h264: move parser-only variables to their own context	10 years ago
Anton Khirnov	cf1e0786ed	error_resilience: move the MECmpContext initialization into ER code Currently, it needs to be initialized by the ER caller (which is currently either a mpegvideo decoder or h264dec). However, since none of those decoders use MECmpContext for anything except ER, it makes more sense to handle it purely inside ER.	10 years ago
Anton Khirnov	f9f883af4f	h264: simplify code in flush_dpb() There is no point in clearing reference explicitly, since that will be done as a part of ff_h264_unref_picture() right below.	10 years ago
Anton Khirnov	60d4c6ff76	h264: restore a block mistakenly removed in `e10fd08a` CC: libav-stable@libav.org Bug-ID: 781	10 years ago

Vittorio Giovara	b1b1a7370e	display: fix order of operands CC: libav-stable@libav.org Bug-Id: CID 1238828 / CID 1238832	10 years ago
Anton Khirnov	7ea1b3472a	lavc: deprecate the use of AVCodecContext.time_base for decoding When decoding, this field holds the inverse of the framerate that can be written in the headers for some codecs. Using a field called 'time_base' for this is very misleading, as there are no timestamps associated with it. Furthermore, this field is used for a very different purpose during encoding. Add a new field, called 'framerate', to replace the use of time_base for decoding.	10 years ago
