* avcodec/nvenc: Add default value for AVCodecContext::refsSrinath K R2017-06-01
| | | | | | | | | | | | | AVCodecContext::refs is used to control the DPB size to be used by the encoder. The default value for AVCodecContext::refs as set in libavcodec/options_table.h is 1. This patch sets AVCodecContext::refs to 0 for h264_nvenc and hevc_nvenc in order to let the driver take the decision of the correct DPB size to use in all cases.

* 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>
