Luca Barbato	0f562f5b83	h264: Do not print an error when the buffer has to be refilled Partially amends `9469370fb3`	10 years ago
Jake Sebastian-Jones	9469370fb3	h264: Use AVERROR return codes instead of -1 And report why it fails. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago
John Högberg	b7040e67ec	h264: fix AVDISCARD_NONKEY for some interlaced content When skip_frame is set to _NONKEY the decoder skips everything except intra slices, which breaks frames that consist of an intra field together with any other field type; half the frame becomes garbage. This patch fixes the issue by letting non-intra slices through if they're part of a keyframe. Signed-off-by: Anton Khirnov <anton@khirnov.net>	10 years ago
Vittorio Giovara	059a934806	lavc: Consistently prefix input buffer defines Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago
Vittorio Giovara	def97856de	lavc: AV-prefix all codec capabilities Express bitfields more simply. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago
Vittorio Giovara	7c6eb0a1b7	lavc: AV-prefix all codec flags Convert doxygen to multiline and express bitfields more simply. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago
Kieran Kunhya	b0017579b6	h264: Add support for Closed Caption export Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago
Vittorio Giovara	271ce76d31	h264: Parse registered data SEI message and AFD value Partially based on code by Marton Balint and Kieran Kunhya. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago
Anton Khirnov	5ec0bdf2c5	h264: do not update the context fields copied between threads after finish_setup() Should fix a large number of possible races with frame threading.	10 years ago
Anton Khirnov	a0f2946068	h264: use properly allocated AVFrames	10 years ago
Anton Khirnov	7a4f74eed5	h264: embed the DPB in the context It now has a fixed size and is initialized only once, so there is no point in allocating it separately.	10 years ago
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	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	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
