Encode WebM videos
Yet another bikeshed to encode WebM videos from CLI.
- Encodes input video to WebM container with VP9 and Opus
- Uses 2-pass encoding, has optional VP8/Vorbis and album art modes
- Fits output file to the size limit by default
- Allows to select video/audio streams and external audio track
- Can burn subtitles into the video
- Flexible set of options and ability to pass raw flags to FFmpeg
- Interactive mode to cut/crop input video with mpv
Optionally put it somewhere in your PATH:
[sudo] wget https://github.com/Kagami/webm.py/raw/master/webm.py -O /usr/local/bin/webm [sudo] chmod +x /usr/local/bin/webm
Or with pip:
[sudo] pip install webm
NOTE: Windows users may want to add Python executable to the PATH. See https://docs.python.org/3/using/windows.html#excursus-setting-environment-variables for details. Otherwise just type the full path to your python.exe location instead of python.
Use webm instead of python webm.py if you installed it with pip.
python webm.py -h
# Fit video to default limit python webm.py -i in.mkv # Fit video to 6 MiB python webm.py -i in.mkv -l 6 # Set video bitrate to 600k python webm.py -i in.mkv -vb 600 # Constrained quality python webm.py -i in.mkv -crf 20 # Constant quality python webm.py -i in.mkv -crf 20 -vb 0 # Encode with VP8 & Vorbis python webm.py -i in.mkv -vp8 # Make album art video python webm.py -cover -i pic.png -aa song.flac
