FFmpeg supports NVENC through the h264nvenc and hevcnvenc encoders. That lasted for a while until I upgraded MCEBuddy to the version 2.5. Initially, I was impressed by the resulting files that were much smaller than expected. This speed is achieved with a Quadro P4000 from NVidia when encoding 1920×1080 movies with. Hi all, About a month ago, I started using Profile ‘HEVC MP4’ to convert WTV files as well as to reconvert previously converted H264 files. NVENC NVENC can be used for H.264 and HEVC encoding. ffmpeg nvenc h265 Mp4 -c:v libx265 -vtag hvc1 -c:a copy output. 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. 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.
