* lavfi: Add OpenCL overlay filterMark Thompson2017-11-22
| | | | | 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.

* hwcontext_opencl: DRM to OpenCL mapping for ARMMark Thompson2017-11-22
| | | | | | | | 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.
* hwcontext_opencl: D3D11 to OpenCL mappingMark Thompson2017-11-22
| | | | Using cl_khr_d3d11_sharing and cl_intel_d3d11_nv12_media_sharing.
* hwcontext_opencl: DXVA2 to OpenCL mappingMark Thompson2017-11-22
| | | | Using cl_khr_dx9_media_sharing.
* hwcontext_opencl: QSV to OpenCL mapping for Intel Media SDKMark Thompson2017-11-22
| | | | | Uses the cl_intel_va_api_media_sharing extension, which supports only NV12 surfaces and only mapping from QSV to OpenCL.
* hwcontext_opencl: VAAPI to OpenCL mapping for Intel i965+beignetMark Thompson2017-11-22
| | | | Supports all surface formats in common between the two.

* doc: Add FAQs about running in background (rev 2)Jim DeLaHunt2017-11-22
| | | | | | | | | | | | | | | | 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>
* avformat/mov: Increment stsd_count while processing stsd data; avoids leaks.Dale Curtis2017-11-22
| | | | | | | | | | 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.

* Fix undefined shift on assumed 8-bit input.Dale Curtis2017-11-21
| | | | | | | | | | | | | 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.
