* vc2enc: replace quantization LUT with a smaller division LUTRostislav Pehlivanov2018-03-10
| | | | | | | | | This commit replaces the huge and impractical LUT which converted coeffs and a quantizer to bits to encode and instead uses a standard multiplication and a shift to replace the division and then codes the values using the regular golomb coding functions.

* lavc/videotoolbox: fix threaded decodingRodger Combs2018-03-08
| | | | | | | | | | | | | | | | | | AVHWAccel.end_frame can run on a worker thread. The assumption of the frame threading code is that the worker thread will change the AVFrame image data, not the AVFrame fields. So the AVFrame fields are not synced back to the main thread. But this breaks videotoolbox due to its special requirements (everything else is fine). It actually wants to update AVFrame fields. The actual videotoolbox frame is now stored in the dummy AVBufferRef, so it mimics what happens in non-videotoolbox cases. (Changing the AVBufferRef contents is a bit like changing the image data.) The post_process callback copies that reference to the proper AVFrame field. Based on a patch by wm4. Signed-off-by: Aman Gupta <aman@tmm1.net>

* avcodec/mediacodecdec: add delay_flush optionAman Gupta2018-03-07
| | | | | | | | | | | | | | | | | | | | | | | | The default behavior of the mediacodec decoder before this commit was to delay flushes until all pending hardware frames were returned to the decoder. This was useful for certain types of applications, but was unexpected behavior for others. The new default behavior with this commit is now to execute flushes immediately to invalidate all pending frames. The old behavior can be enabled by setting delay_flush=1. With the new behavior, video players implementing seek can simply call flush on the decoder without having to worry about whether they have one or more mediacodec frames still buffered in their rendering pipeline. Previously, all these frames had to be explictly freed (or rendered) before the seek/flush would execute. The new behavior matches the behavior of all other lavc decoders, reducing the amount of special casing required when using the mediacodec decoder.

* lavc/qsvenc: disable h264 look_ahead by defaultZhong Li2018-03-06
| | | | | | | | | | | Look_ahead can provide quality improvements, but would better disable it by default due to some reasons: 1. It is only available for some codecs (e.g. HEVC is not supported) on Intel Haswell and plus platforms. Thus means it will be failed on some platforms. 2. It significantly increases encoding latency and memory consumption. 3. It may overwrite some other options such as CBR and CAVLC.

* | avcodec/nvenc: Declare support for P016Philip Langdale2018-03-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nvenc doesn't support P016, but we have two problems today: 1) We declare support for YUV444P16 which nvenc also doesn't support. We do this because it's the only pix_fmt we have that can approximate nvenc's internal format that is YUV444P10 with data in MSBs instead of LSBs. Because the declared format is a 16bit one, it will be preferrentially chosen when encoding >10bit content, but that content will normally be YUV420P12 or P016 which should get mapped to P010 and not YUV444P10. 2) Transcoding P016 content with nvenc should be possible in a pure hardware pipeline, and that can't be done if nvenc doesn't say it accepts P016. By mapping it to P010, we can use it, albeit with truncation. I have established that swscale doesn't know how to dither to 10bits so we'd get truncation anyway, even if we tried to do this 'properly'.
