Anton Khirnov	8ea15afbf2	hwcontext_qsv: transfer data through the child context when VPP fails ... Uploading/downloading data through VPP may not work for some formats, in that case we can still try to call av_hwframe_transfer_data() on the child context.

Anton Khirnov	b91ce48600	hwcontext_qsv: do not fail when download/upload VPP session creation fails ... Certain pixel formats (e.g. P8) might not be supported for download/upload through VPP operations, but can still be used otherwise.

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. Signed-off-by: Maxym Dmytrychenko <maxym.dmytrychenko@intel.com>	2016-11-07 12:47:20 +01:00
