Mark Thompson	0f93cef2d6	hwcontext: Perform usual uninitialisation on derived frames contexts	7 years ago
Mark Thompson	5514bab37a	vf_hwmap: Pass mapping mode when deriving frames context on an existing device To match creation on a newly-derived device. (This was missed earlier because the mode is only used in some cases.)	7 years ago
Mark Thompson	7faa8d8b03	lavfi: Add OpenCL unsharp mask filter Intended to replace existing opencl mode of the unsharp filter. Supports many more pixel formats and works without immediate upload and download of frame data. The options are compatible with the existing filter.	7 years ago
Mark Thompson	9204b2deea	lavfi: Add OpenCL overlay filter Input and output formats must be the same, the overlay format must be the same as the input except possibly with an additional alpha component.	7 years ago
Mark Thompson	59d6529333	lavfi: Add infrastructure for building OpenCL source into libavfilter	7 years ago
Mark Thompson	5c21c41b7d	lavfi: Add some common code for OpenCL filtering	7 years ago
Mark Thompson	7faae6e745	hwcontext_opencl: DRM to OpenCL mapping for ARM Using cl_arm_import_memory. Unfortunately, despite this not being a standard extension, the function clImportMemoryARM() is not accessible via clGetExtensionFunctionAddressForPlatform(). This means that it has to be linked directly to the ARM OpenCL binary, so making a portable binary is not possible as it is with all other mapping extensions.	7 years ago
Mark Thompson	f06754e4f3	hwcontext_opencl: D3D11 to OpenCL mapping Using cl_khr_d3d11_sharing and cl_intel_d3d11_nv12_media_sharing.	7 years ago
Mark Thompson	9e7cda1b1e	hwcontext_opencl: DXVA2 to OpenCL mapping Using cl_khr_dx9_media_sharing.	7 years ago
Mark Thompson	403cde8e85	hwcontext_opencl: QSV to OpenCL mapping for Intel Media SDK Uses the cl_intel_va_api_media_sharing extension, which supports only NV12 surfaces and only mapping from QSV to OpenCL.	7 years ago
Mark Thompson	eb3e9f469a	hwcontext_opencl: VAAPI to OpenCL mapping for Intel i965+beignet Supports all surface formats in common between the two.	7 years ago
Mark Thompson	b25d8ef0a7	lavu: OpenCL hwcontext implementation	7 years ago
Mark Thompson	a050f56c09	lavu: Add OpenCL hardware pixfmt	7 years ago
Jim DeLaHunt	152902f379	doc: Add FAQs about running in background (rev 2) Add two FAQs about running FFmpeg in the background. The first explains the use of the -nostdin option in a straightforward way. Text revised based on review. The second FAQ starts from a confusing error message, and leads to the solution, use of the -nostdin option. The purpose of the second FAQ is to attract web searches from people having the problem, and offer them a solution. Add an anchor to the Main Options section of the ffmpeg documentation, so that the FAQs can link directly there. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	7 years ago
Dale Curtis	6db511a783	avformat/mov: Increment stsd_count while processing stsd data; avoids leaks. In the event of ff_mov_read_stsd_entries() failure, sc->stsd_count is not updated, even if the function allocates extradata memory. Instead update the sc->stsd_count as entries are parsed so that mov_read_close() can do the right thing.

Dale Curtis	7010dd98b5	Fix undefined shift on assumed 8-bit input. decode_user_data() attempts to create an integer \|build\| value with 8 bits of spacing for 3 components. However each component is an int32_t, so shifting each component is undefined for values outside of the 8 bit range. This patch simply clamps input to 8-bits per component and prints out a warning that the values were clamped.
