For me, even with this applied, I still get the same old error: [h264_nvenc @ 0x257c400] EncodePicture failed!: no encode device (1) Using nvidia-drivers 381.22
Timo,

We are working on another patch which will fix hw accelerated transcode (with -hwaccel cuvid) for bf > 0 and will send out for review soon. Thanks

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.
