* avcodec/nvenc: surface allocation reductionBen Chang2017-04-26
| | | | | | | | | | | | | | | | This patch aims to reduce the number of input/output surfaces NVENC allocates per session. Previous default sets allocated surfaces to 32 (unless there is user specified param or lookahead involved). Having large number of surfaces consumes extra video memory (esp for higher resolution encoding). The patch changes the surfaces calculation for default, B-frames, lookahead scenario respectively. The other change involves surface selection. Previously, if a session allocates x surfaces, only x-1 surfaces are used (due to combination of output delay and lock toggle logic). To prevent unused surfaces, changing surface rotation to using predefined fifo. Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>

* avcodec/nvenc: include nvEncodeAPI v7 SDK headerTimo Rothenpieler2016-08-28
| | | | | | | | | | | | | As Nvidia has put the most recent Video Codec SDK behind a double registration wall, of which one needs manual approval of a lenghty application, bundling this header saves everyone trying to use NVENC from that headache. The header is still MIT licensed and thus fine to bundle with ffmpeg. Not bundling this header would get ffmpeg stuck at SDK v6, which is still freely available, holding back future development of the NVENC encoder.
