Note that in this example the audio stream of the input file is simply stream copied over to the output and not re-encoded. To clarify, I include a player test program I wrote until now. Ability to add your own custom high-performance CUDA filters using the shared CUDA Dec 12, 2023 · The Advanced Media Framework (AMF) SDK provides developers with easy access to AMD GPUs for multimedia processing. Use the CPU to decode the input bitstream, and the GPU to encode the output stream. mkv -vf "scale_qsv=w=1920:h=1080" -c:v h265_qsv -preset veryslow -global_quality 18 output. Jan 26, 2015 · ffmpeg -i in. We have been listening and gathering feedback from the industry during the past year, and developed tools that users told us useful but missing in GPU video processing. Feb 3, 2023 · After some trying to launch minterpolate from latest FFMpeg, it is very surprising for me about very old FFMpeg "feat" from more than ten years ago - it is still cant use GPU nor CPU properly from the box (seriously, 0-5% gpu 33% cpu?). On linux, use . In your case, you'll need to build FFmpeg from source. We used the libvmaf_cuda video filter for the GPU implementation and the libvmaf video filter for the CPU implementation. Once you know the index, the -hwaccel_device index flag can be used to set the active GPU for decoding and encoding. Execute ffmpeg -h encoder=h264_nvenc for getting a list of options. Note that while using the GPU video encoder and Jan 7, 2019 · If you're on Windows, you can access the related encoders via AMF, aptly named h264_amf and hevc_amf, whose usage can be viewed via: ffmpeg -h encoder=h264_amf. The other two input video streams have codecs PNG and QTRLE, for which, no hardware acceleration is available. FFmpeg enables the encoded video to be read into GPU or CPU RAM directly instead of reading the raw byte streams from disk, as the VMAF tool does. c or nvenc_hevc. On Linux the established API for this is VA-API, which FFmpeg supports. For hardware accelerated encoding use h264_nvenc instead of libx264. g. Jan 4, 2024 · The benchmark tests encoding the target videos into H. If I use this command: ffmpeg -c:v h264_cuvid -i %arg1% -c:v hevc_nvenc -b:v 2M -c:a copy -tag:v hvc1 Sep 20, 2019 · just remove ffmpeg package. c file, there's no code that uses "gpu" option. ffmpeg -h encoder=hevc_amf. ffmpeg -i /home/M. png Sample H. 265) while also ensuring as high quality as possible - really the optimum trade off (which is what I think everyone is going for when encoding lossy). 6x speed on average (GPU at around 55%; CPU at around 33%; RAM at around 33%) - so a 2 hour movie in about 33 minutes. You may also try accelerated MJPEG decoding by adding -vcodec mjpeg_cuvid before the -i. mpg -vcodec h264_nvenc -gpu 0 -acodec copy -f mpegts output_video. These chips advertise stuff like "Decode 4k/30FPS, Encode 1080p,30FPS" as the capabilities of the GPU for encoding and decoding videos. 265 the hevc_nvenc. I have a Nvidia pascal-based card, which supports yuv444 10 bit (as 'yuv444p16le') and when when using '-c:v hevc_nvenc' the auto_scaler kicks in and converts to 'yuv444p16le Mar 15, 2021 · i'm using ffmpeg and an NVIDIA for my video transcode process. I use ffmpeg to process some audios as follow, fmpeg -i input. Luckily, Google Colab GPU instance comes already configured with CUDA and the pre-built binaries included in this repository were built/compiled in the same environment. mkv" -c:v h264_nvenc -preset slow "output. See this issue for more on this application notice. I got the latest version binaries of ffmpeg from here. I am also able to transcode using the cpu using What that does is pass the "-threads" option to ffmpeg to make ffmpeg use more threads/cores to encode. er kq uf tv fo yn sm by af fy
