krzemienski / ffmpeg-gnu-parallel-snippets.md

Created June 11, 2023 19:16 — forked from Brainiarc7/ffmpeg-gnu-parallel-snippets.md

Some snippets you can quickly adapt for use with FFmpeg and GNU Parallel for use for standard tasks.

Useful Examples of ffmpeg and GNU parallel on the command-line:

Transcoding FLAC music to Opus:

ffmpeg is a highly useful application for converting music and videos. However, audio transcoding is limited to a a single core. If you have a large FLAC archive and you wanted to compress it into the efficient Opus codec, it would take forever with the fastest processor to complete, unless you were to take advantage of all cores in your CPU.

parallel 'ffmpeg -v 0 -i "{}" -c:a libopus -b:a 128k "{.}.opus"' ::: $(find -type f -name '*.flac')

Transcoding Videos to VP9:

See the supported NVENC and NPP capabilities in your FFmpeg build

Quickly check for supported NVENC and NPP hardware acceleration capabilities in FFmpeg on your platform:

Depending on how you built ffmpeg, you may want to check the supported NVENC-based hardware acceleration capabilities in ffmpeg by running:

$ for i in encoders decoders filters; do
    echo $i:; ffmpeg -hide_banner -${i} | egrep -i "npp|cuvid|nvenc|cuda|nvdec"
done

Sample output (as on my testbed):
