* avcodec: add Amuse Graphics decoderPaul B Mahol2019-03-31
| | | | This work is sponsored by VideoLAN.
* avutil/hcontext_cuda: Remove unnecessary stream synchronisationPhilip Langdale2019-03-30
| | | | | | | Similarly to the previous changes, we don't need to synchronise after a memcpy to device memory. On the other hand, we need to keep synchronising after a copy to host memory, otherwise there's no guarantee that subsequent host reads will return valid data.
* avcodec/cuviddec: Remove unnecessary stream synchronisationPhilip Langdale2019-03-30
| | | | | | | | We're also doing a sync here after copying the frame to be passed on down the pipleine. And it is also unnecessary. I was able to demonstrate a 33% speedup removing the sync from an example transcode pipeline.
* avfilter/vf_yadif_cuda: Remove unnecessary stream synchronisationPhilip Langdale2019-03-30
| | | | | | | | | | | | | | I put this call in by habit, rather than because there was any actual need. The filter is simply processing frames one after the other and has no need to synchronise. malakudi on the devtalk forums noticed a slowdown when using nvenc with temporal/spatial aq and that the slowdown went away if the sync call was removed. I also verified that in the basic encoding case there's an observable speedup. I also verified that we aren't doing unnecessary sync calls in any other filter.

* fftools/ffmpeg: Check if we do have also a filter_complex filter.Thierry Foucu2019-03-28
| | | | | | | | | | | | | | | | | Right now, the code check for no filter description, but if we use a filter_complex, the code will use the AVFrame.duration which could be wrong in case of using fps filter. How to reproduce the problem: ffmpeg -f lavfi -i testsrc=duration=1 -vf fps=fps=50 -vsync 1 -f null - output 50 frames ffmpeg -f lavfi -i testsrc=duration=1 -filter_complex fps=fps=50 -vsync 1 -f null - output 51 frames With this commit, the same command will always output 50 frames.

* lavc/qsvenc_h264: remove the privite option trellisZhong Li2019-03-28
| | | | | | | | | | | | | | | | | | There are many problems of current qsv trellis option: 1. Duplicated with AVCodecContext definition 2. MFX_TRELLIS_XXX is introduced by MSDK API 1.17 Currently Without MSDK API checking thus may cause compilation issue. 3. user is inclined to enable trellis when set "-trellis 1", but actually it is to disable since MFX_TRELLIS_OFF is equal to 1. 4. It is too complex for user to enable trellis for every frame(I/P/B). Just simply remove the private option, and switch to the AVCodecContext definition. Compatibility should not a big problem (except can't exact map) since the option name is same as AVCodecContext.

* avfilter/vf_lensfun: add scale parameterDaniel Playfair Cal2019-03-25
| | | | | | | | | | | | | | | | | | | The lensfun filter wraps the lensfun library which performs transformations on videos to correct for lens distortion. Often this results in areas in the input being mapped to areas that fall outside the boundaries of the output. The library has a parameter called scale which is a scale factor applied to the output video. By decreasing it it is possible to regain the areas of the video which would otherwise have been lost. There is a special value of 0 which indicates that the library should automatically determine a scale factor that results in the output frame being filled (i.e. little or no black/unmapped areas). This patch adds a corresponding scale option to the lensfun filter which is passed through to the library. The existing behaviour of using the automatic value of 0 is retained as the default behaviour, while other values will be passed through to the library.
