FFmpeg supports NVENC through the h264nvenc and hevcnvenc encoders. NVENC NVENC can be used for H.264 and HEVC encoding. You can get encoder documentation in ffmpeg like this: ffmpeg -h encoderhevcnvenc: Encoder hevcnvenc NVIDIA NVENC hevc encoder: General capabilities. The only thing that was added to NVDEC was AV1 decode.
That can be used by filters with complex requirements to use the format negotiated on one link to set the formats supported on another. FFmpeg refers to NVENC/NVDEC interconnect as CUDA. I heard there was some improvements to the Ampere generation for H265 encoding with NVENC That's wrong. of LibAVCodec that is used in applications like HandBrake, FFMPEG, and VLC. Although FFMPEG support NVENC, but just not by default, and you have to compile it yourself. Filter the word “frame” indicates either a video frame or a group of audio as stored in an AVFrame structure Format for each input and each output the list of supported formats For video that means pixel format For audio that means channel sample they are references to shared objects When the negotiation mechanism computes the intersection of the formats supported at each end of a all references to both lists are replaced with a reference to the intersection And when a single format is eventually chosen for a link amongst the remaining all references to the list are updated That means that if a filter requires that its input and output have the same format amongst a supported all it has to do is use a reference to the same list of formats query_formats can leave some formats unset and return AVERROR(EAGAIN) to cause the negotiation mechanism toagain later. HEVC offers x264-equivalent image quality at a lower bitrate or superior 7.
