* examples/hw_decode: Use hw-config information to find pixfmtMark Thompson2017-11-291-32/+22
| | | | This removes all remaining device-type specificity.

* libvpxenc,vp9: add corpus-complexity optionJames Zern2017-11-281-0/+5
| | | | | | | | | | Corpus VBR mode is a variant of standard VBR where the complexity distribution midpoint is passed in rather than calculated for a specific clip or chunk. The valid range is [0, 10000]. 0 (default) uses standard VBR. Signed-off-by: James Zern <jzern@google.com>

* avfilter/drawbox: rename variable for maximum thicknessGyan Doshi2017-11-281-2/+3
| | | | | | | | | The present value name for maximum thickness is 'max' which results in a parse error of any thickness expression containing 'max(val1,val2)'. Value renamed to 'fill'. Tested locally and documented. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* lavu,lavfi,ffmpeg: Remove experimental OpenCL APIMark Thompson2017-11-223-38/+3
| | | | | | | | | | | This was added in early 2013 and abandoned several months later; as far as I can tell, there are no external users. Future OpenCL use will be via hwcontext, which requires neither special OpenCL-only API nor global state in libavutil. All internal users are also deleted - this is just the unsharp filter (replaced by unsharp_opencl, which is more flexible) and the deshake filter (no replacement).

* doc: Add FAQs about running in background (rev 2)Jim DeLaHunt2017-11-222-0/+66
| | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | For some strange reason "-t" option was only implemented for input files while both "-t" and "-to" were available for use for output files. This made extracting a range from input file inconvenient. This patch enables -to option for input so one can do ffmpeg -ss 1:23:20 -to 1:27:22.3 -i myinput.mkv ...

| * lavc: external hardware frame pool initializationwm42017-10-191-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | This adds a new API, which allows the API user to query the required AVHWFramesContext parameters. This also reduces code duplication across the hwaccels by introducing ff_decode_get_hw_frames_ctx(), which uses the new API function. It takes care of initializing the hw_frames_ctx if needed, and does additional error handling and API usage checking. Support for VDA and Cuvid missing.

| * Remove all output devicesDiego Biurrun2017-10-133-35/+0
| | | | | | | | | | | | The libavformat API is not suitable for exporting output devices as muxers. Some practical problems are e.g. lack of timing/synchronization mechanisms or interaction with output-specific features.

| | | | | | | | Also enable MPEG-2 support in the trace_headers filter.
| * lavc: Add hevc_metadata bitstream filterMark Thompson2017-08-131-0/+54
| | | | | | | | | | This is able to modify some header metadata found in the VPS/SPS/VUI, and can also add/remove AUDs.
| * lavc: Add h264_redundant_pps bitstream filterMark Thompson2017-08-131-0/+9
| | | | | | | | | | | | | | | | | | This applies a specific fixup to some Bluray streams which contain redundant PPSs modifying irrelevant parameters of the stream which confuse other transformations which require correct extradata. A new single global PPS is created, and all of the redundant PPSs within the stream are removed.
| * lavc: Add h264_metadata bitstream filterMark Thompson2017-08-131-0/+63
| | | | | | | | | | This is able to modify some header metadata found in the SPS/VUI, and can also add/remove AUDs and insert user data in SEI NAL units.
| * lavc: Add trace_headers bitstream filterMark Thompson2017-08-121-0/+8
| | | | | | | | | | Supports all streams that the coded bitstream infrastructure does (currently H.264 and H.265).
| * vaapi_encode: Move quality option to common codeMark Thompson2017-08-061-3/+6
| | | | | | | | | | | | | | | | | | Use AVCodecContext.compression_level rather than a private option, replacing the H.264-specific quality option (which stays only for compatibility). This now works with the H.265 encoder in the i965 driver, as well as the existing cases with the H.264 encoder.
