The built-in presets offer a good range of options. With ffmpeg and a decent GPU (like a Quadro P4000) the h265/HEVC encoder finaly gets a good speedboost with up to 90fps when encoding HD movies with the below parameter values and 200fps when using the GPU accelerated h264 encoder. I notice a lot of new presets TBH, i could guess but well, I'm no good at. ffmpeg -i input. Is there a way to specify GPU encoding device?

I see ffmpeg supports nvenc, I tried some command line tests but just kept getting errors, no luck, doing something wrong. sudo snap install ffmpeg And thats it, you can use *_nvenc codecs now. NVidia® Products with the Kepler, Maxwell and Pascal generation GPUs contain a dedicated accelerator for video encoding and decoding, called NVENC, on the GPU die. Note that this filter is not FDA approved, nor are we medical professionals. 264 encoding engine can be used (and it doesn't make the shader processors. NVENC is incredibly efficient, so most users can select the maximum setting. FFmpeg and its photosensitivity filter are not making any medical claims.

If you're not familiar with x264 presets, this quote from the ffmpeg wiki sums it up nicely: "A preset is a collection of options that will provide a certain encoding speed to compression ratio. That is fixed now. Hardware-accelerated encoders: In the case of NVIDIA, NVENC is supported and implemented via the h264_nvenc and the hevc_nvenc wrappers.

NVENC's results are interesting, because the preset selected has only a slight effect on picture quality. NVENC is somewhat similar to CUDA, thus it works even from terminal session. Hardware-accelerated encoders: In the case of NVIDIA, NVENC is supported and implemented via the h264_nvenc and the hevc_nvenc wrappers. Although I think Speed=0. Use FFmpeg/libav binary as required. Being a daily CentOS/RHEL 7 user I also want to support the latest and gretest of the same software on that platform, which also means rebuilding some official CentOS/RHEL 7 packages like VP8/9, VDPAU and VA-API libraries. mp4 -r 1 -f image2 image-%2d. mp4 -c:v h264_nvenc -gpu list -f null – Once you know the index, the -hwaccel_device index flag can be used to set the active GPU for decoding and encoding.
