* avcodec/nvenc: support dynamic bitrate changespkviet2018-05-04
| | | | | | | | | The patch enables dynamic bitrate through ReconfigureEncoder method from nvenc API. This is useful for live streaming in case of network congestion. Signed-off-by: pkviet <pkv.stream@gmail.com> Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>
* avcodec/nv{enc,dec}: use sane version checking macroTimo Rothenpieler2018-04-13
| | | | | For some odd reason, the Nvidia version macros puts the minor version in the msb, so comparing against it is impossible.
* avcodec/nvenc: add support for B frames as refTimo Rothenpieler2018-04-11

* compat: remove in-tree NVidia headersTimo Rothenpieler2018-02-27
| | | | | | | | | | | | | | | | External headers are no longer welcome in the ffmpeg codebase because they increase the maintenance burden. However, in the NVidia case the vanilla headers need some modifications to be usable in ffmpeg therefore we still provide them, but in a separate repository. The external headers can be found at https://git.videolan.org/?p=ffmpeg/nv-codec-headers.git Fate-source is updated because of the deleted files, and dynlink_loader.h license headers were updated with the standard FFmpeg headers.

* avcodec/nvenc: refcount input frame mappingsTimo Rothenpieler2018-01-28
| | | | | | | | If some logic like vsync in ffmpeg.c duplicates frames, it might pass the same frame twice, which will result in a crash due it being effectively mapped and unmapped twice. Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>

* 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.
