* hwcontext_vaapi: Don't abort on failing to allocate from a fixed-size poolMark Thompson2016-11-26
|
* arm: warn/error on movrelx usage problematic with PIC on ELFJanne Grunau2016-11-24
| | | | | | The warning has false positives but our asm does not trigger it. For new code false positives can only be avoided by changing the register allocation.

* hwcontext_dxva2: make sure the sw frame format is the right one during transferAnton Khirnov2016-11-18
|
* hwcontext_dxva2: split transfer_data() into upload/download functionsAnton Khirnov2016-11-18
| | | | | | 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.
* hwcontext_dxva2: fix handling of the mapping flagsAnton Khirnov2016-11-18
| | | | | | D3DLOCK_READONLY properly corresponds to the absence of the write flag, not to the presence of the read flag, while D3DLOCK_DISCARD is equivalent to the overwrite flag.
* hwcontext_dxva2: do not assume the destination format during mapping is ↵Anton Khirnov2016-11-18
| | | | | | always the right one Handle the cases where it is unsupported or unset.
* arm: Clear the gp register alias at the end of functionsMartin Storsjö2016-11-10
| | | | | | | | | | | We reset .Lpic_gp to zero at the start of each function, which means that the logic within movrelx for clearing gp when necessary will be missed. This fixes using movrelx in different functions with a different helper register. Signed-off-by: Martin Storsjö <martin@martin.st>
* aarch64: Add an offset parameter to the movrel macroMartin Storsjö2016-11-10
| | | | | | | | | With apple tools, the linker fails with errors like these, if the offset is negative: ld: in section __TEXT,__text reloc 8: symbol index out of range for architecture arm64 Signed-off-by: Martin Storsjö <martin@martin.st>

* hwcontext_qsv: transfer data through the child context when VPP failsAnton Khirnov2016-11-07
| | | | | | | | 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. Signed-off-by: Maxym Dmytrychenko <maxym.dmytrychenko@intel.com>
* hwcontext_qsv: do not fail when download/upload VPP session creation failsAnton Khirnov2016-11-07
| | | | | | | Certain pixel formats (e.g. P8) might not be supported for download/upload through VPP operations, but can still be used otherwise. Signed-off-by: Maxym Dmytrychenko <maxym.dmytrychenko@intel.com>
* hwcontext_qsv: add support for the P8 formatAnton Khirnov2016-11-07
| | | | | | | | | | | | 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>
* hwcontext_dxva2: add support for the P8 formatAnton Khirnov2016-11-07
| | | | | | | This format is used internally by the QSV encoder to store the encoded bitstream. Signed-off-by: Maxym Dmytrychenko <maxym.dmytrychenko@intel.com>

* hwcontext_vaapi: Frame mapping supportMark Thompson2016-11-03
| | | | | Can map to any supported software format (using a GPU copy if it doesn't actually match the surface format underneath).
* hwcontext: Hardware frame mappingMark Thompson2016-11-03
| | | | | | | | | | Adds the new av_hwframe_map() function, which allows mapping between hardware frames and normal memory, along with internal support for implementing it. Also adds av_hwframe_ctx_create_derived(), for creating a hardware frames context associated with one device using frames mapped from another by some hardware-specific means.

* hwcontext_vaapi: add a quirk for the missing MemoryType attributeAnton Khirnov2016-10-02
| | | | | | The Intel binary iHD driver does not support the VASurfaceAttribMemoryType, so surface allocation will fail when using it.

* hwcontext_vaapi: Try the first render node as the default DRM deviceMark Thompson2016-08-13
| | | | | | | | | | If no string argument is supplied when av_hwdevice_ctx_create() is called to create a VAAPI device, we currently only try the default X11 display (that is, $DISPLAY) to find a device, and will therefore fail in the absence of an X server to connect to. Change the logic to also look for a device via the first DRM render node (that is, "/dev/dri/renderD128"), which is probably the right thing to use in most simple configurations which only have one DRM device.
* buffer: fix av_buffer_pool_init2() documentationAnton Khirnov2016-08-11
| | | | | | A non-existent av_buffer_pool_can_uninit() function is mentioned instead of av_buffer_pool_uninit(). Also, this function is to be called by the caller, not the pool itself.
* buffer: fix av_buffer_realloc() when the data is offset wrt buffer startAnton Khirnov2016-08-03
| | | | | | | | | In such a case behave as if the buffer was not reallocatable -- allocate a new one and copy the data (preserving just the part described by the reference passed to av_buffer_realloc). CC: libav-stable@libav.org Reported-By: wm4 <nfxjfg@googlemail.com>
