Anton Khirnov e18ba2dfd2 hwcontext_dxva2: make sure the sw frame format is the right one during transfer 2016-11-18 10:31:53 +01:00
Anton Khirnov 5a1d605cea hwcontext_dxva2: split transfer_data() into upload/download functions 
Just the presence of a hw frames context is not enough to detect whether
the transfer is an upload or a download, because hw frames mapped to
system memory will have a hw frames context attached.

Anton Khirnov 9d7026574b hwcontext_dxva2: fix handling of the mapping flags

equivalent to the overwrite flag.

Anton Khirnov b91ce48600 hwcontext_qsv: do not fail when download/upload VPP session creation fails

Anton Khirnov b115a35ea6 hwcontext_qsv: add support for the P8 format 
When using GPU surfaces with QSV, one needs to supply a frame allocator,
which will be invoked to pass surface pools to libmfx.
For encoding, this allocator gets invoked not only for the pool of input
frames, but also for a separate pool of (apparently) reconstructed frames
and another pool of MFX_FOURCC_P8, which on Windows needs to return
D3DFMT_P8 D3D surfaces. Those are probably used to store the encoded
bitstream on the GPU.

 2016-10-21 10:11:20 +02:00
Anton Khirnov 8e2ea69135 lavf: use the new bitstream filter for extracting extradata 
This also fixes a minor bug introduced in the codecpar conversion, where
the termination condition for extracting the extradata does not match
the actual extradata setting code. As a result, the packet durations
made up by lavf go back to their values before the codecpar conversion.
That is of little consequence since that code should eventually be
dropped completely.

Anton Khirnov c359d624d3 hevcdec: move decoder-independent declarations into a separate header 
This way they can be reused by other code without including the whole
decoder-specific hevcdec.h
Also, add the HEVC_ prefix to them, since similarly named values exist
for H.264 as well and are sometimes used in the same code.
 2016-10-16 20:26:28 +02:00
Anton Khirnov 4abe3b049d hevc: rename hevc.[ch] to hevcdec.[ch] 
This is more consistent with the rest of libav and frees up the hevc.h

Anton Khirnov 27085d1b47 avconv: only retry decoding on actual decoding errors 
Errors during decoding are currently considered non-fatal and do not
terminate transcoding, so even if parts of the data are corrupted, the
rest may be decodable.

However, that should apply only to the actual decoding calls, not to the
failures elsewhere (e.g. configuring filters).
 2016-10-02 11:41:45 +02:00
Anton Khirnov f6772e9bf8 avconv: make sure the filtergraph is freed on init failure 
The filtergraph's existence is used in several places to mean that the
filtergraph is fully configured. This causes problems if it's allocated,
but the initialization fails (e.g. if a non-existent filter is
specified).

Anton Khirnov 6755eb5b21 mss12: validate display dimensions 
The code currently reads the coded dimensions from the extradata, but

than the coded size).

Make sure that when the display dimensions are set, they are also valid.
