Anton Khirnov d7bebe4805 hevc: skip invalid/ignored NALUs when splitting the packet 
There is no need to wait until actually decoding the NALU. This will
allow to get rid of the second hls_nal_unit() call later.
 2015-07-12 18:15:39 +02:00
Anton Khirnov b11acd5732 hevc: remove HEVCContext usage from hevc_ps 
Factor out the parameter sets into a separate struct and use it instead.

This will allow us to reuse this code in the parser.

Anton Khirnov ab05ed4c32 mpegvideo_parser: export pixel format and dimensions 2015-07-12 18:15:39 +02:00
Anton Khirnov a9a2f36130 doc: add a section about building with libmfx 2015-07-12 18:15:39 +02:00
Anton Khirnov 86eee85dad bytestream2: set the reader to the end when reading more than available 
This prevents possible infinite loops with the calling code along the
lines of while (bytestream2_get_bytes_left()) { ... }, where the reader
does not advance.

Anton Khirnov 69ab9f53f9 hevc: split bitstream unescaping to a separate file 
It will be useful in the QSV HEVC encoder.

Anton Khirnov fd124d8357 hevc_ps: split the code for parsing the SPS and exporting it into the context 
This will be useful in the later commits, where we want to parse an SPS
without having a whole decoding context.

Anton Khirnov 441e8ae5ef FATE: drop the last truncated frame from the wmapro tests 
Since it's truncated, the result depends on how specifically the demuxer
and the decoder handle errors.

Anton Khirnov d3ea79e8a6 FATE: drop the last truncated frame from the wma lossless test 
Since it's truncated, the result depends on how specifically the demuxer
and the decoder handle errors.

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.
 2015-06-27 16:48:48 +02:00
Anton Khirnov 6d4d3fee63 h264: make sure the current picture is not made a long ref multiple times 
Fixes possible invalid reads, once one of those refs is freed, but the
others remain.

Anton Khirnov 9a5e4fbec8 avconv: do not stop processing the input packet on decoding error 
We still want to flush the filters on EOF and possibly apply streamcopy.
 2015-06-27 16:45:41 +02:00
Anton Khirnov b114f6d48a avconv: factor out flushing the filters 
This also ensures this is always done, avoiding infinite loops if an
error occurs at the end of the input.
 2015-06-27 16:45:04 +02:00
Anton Khirnov e49e0f58e2 h264: make sure the slices do not overlap during slice threading

Anton Khirnov 3735b5c616 Revert "lavfi: always check av_expr_parse_and_eval() return value" 
This reverts commit 63be97ec40.

All those calls were unchecked on purpose, as explained in the comments
in the code.

Anton Khirnov a09c499a2e rawenc: properly allocate coded_frame 2015-04-29 05:52:58 +02:00
Anton Khirnov a0f2946068 h264: use properly allocated AVFrames 2015-04-29 05:52:58 +02:00
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.
 2015-04-29 05:52:58 +02:00
Anton Khirnov 88c612e3a4 h264: merge the init and reinit paths in update_thread_context() 
There is no real need to handle the init case specially, everything
necessary is initialized in the reinit code as well.
 2015-04-29 05:52:58 +02:00
Anton Khirnov 8a66fd4026 h264: drop the reinit parameter from init_slice_header() 
It is only used to decide whether to call free_tables(), but that
function is safe to call on an uninitialized context as well.
 2015-04-29 05:52:58 +02:00
Anton Khirnov c9ccbc7333 h264: update the current bit depth/chroma type in init_slice_header() 
With frame threading, it is currently only updated in the context where
the change occurs, but not in any other contexts.
 2015-04-29 05:52:58 +02:00
Anton Khirnov 29dcde2b87 h264: copy nal_length_size in update_thread_context 
It does not make sense to copy is_avc without copying this as well. This
patch should not change anything for now, but will have an effect in
later commits.
 2015-04-29 05:52:58 +02:00
Anton Khirnov 440e8dd374 h264: drop a comment that carries no useful information 2015-04-29 05:52:58 +02:00
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.
 2015-04-29 05:52:58 +02:00
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.
 2015-04-29 05:52:57 +02:00
Anton Khirnov 54986d6db9 h264: move context reinit lower down in update_thread_context() 
It uses some fields from the SPS, which is not yet set where the reinit
is called currently.
 2015-04-29 05:52:57 +02:00
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.
 2015-04-29 05:52:57 +02:00
Anton Khirnov 9d33bab583 h264: drop H264Context.ouputed_poc 
It is only set, but never used for anything.
 2015-04-29 05:52:57 +02:00
Anton Khirnov 27b0e6ebfd h264: drop needs_realloc 
It is not needed anymore since switching to refcounted frames.
 2015-04-29 05:52:57 +02:00
Anton Khirnov 249796e256 svq3: initialize some required H264Context fields. 
They are no longer initialized in ff_h264_decode_init() since 43fd3dd,
so svq3 needs to initialize the manually.

Fixes svq3 decoding, broken since 43fd3dd.
 2015-04-05 21:02:56 +02:00
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.

Anton Khirnov 65afa65e73 h264: drop redundant initialization of the scaling matrices 
It will always be initialized when actually parsing the PPS.

Anton Khirnov e1f907711a h264: factor out common code from init() and init_thread_copy() 2015-04-05 12:02:35 +02:00
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.
 2015-04-05 12:02:26 +02:00
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.

Anton Khirnov 84f226a3bc h264: use the correct SPS during PPS parsing 
There is in general no reason for the currently active SPS to be the one
referenced by the PPS being parsed.

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.

Anton Khirnov 3892bdab9b avconv: do not overwrite the stream codec context for streamcopy 
Since we are not doing encoding, there is no point in ever touching the
separate encoding context. Always use the stream codec context.

Fixes writing attachments.

Anton Khirnov 7693ba0a0e hevc: export stream parameters from extradata

Anton Khirnov 1ae7afd256 hevc: split out setting AVCodecContext parameters 
Additionally always set the software pixel format, so it's available

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

slice context.

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

later.

Anton Khirnov 36d04801ba h264: move the scratch buffers into the per-slice context

previous method.
