* 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.

| | | | | | | | | | | | 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.

| | | | | | | | | | This is able to modify some header metadata found in the VPS/SPS/VUI, and can also add/remove AUDs.

| | | | | | | | | | | | | | | | | | 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.

| * 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.
| * imgutils: add function to clear an image to blackwm42017-07-261-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Black isn't always just memset(ptr, 0, size). Limited YUV in particular requires relatively non-obvious values, and filling a frame with repeating 0 bytes is disallowed in some contexts. With component sizes larger than 8 or packed YUV, this can become relatively complicated. So having a generic function for this seems helpful. In order to handle the complex cases in a generic way without destroying performance, this code attempts to compute a black pixel, and then uses that value to clear the image data quickly by using a function like memset. Common cases like yuv410p10 or rgba can't be handled with a simple memset, so there is some code to fill memory with 2/4/8 byte patterns. For the remaining cases, a generic slow fallback is used.

| | | | | | | | | | | | | | | | | | | | This also adds support to avconv (which is trivial due to the new hwaccel API being generic enough). The new decoder setup code in dxva2.c is significantly based on work by Steve Lhomme <robux4@gmail.com>, but with heavy changes/rewrites. Signed-off-by: Diego Biurrun <diego@biurrun.de>
