Automatically transcode video (and audio) files in a directory. This is my automated fix to DaVinci Resolve only supporting a very specific set of video formats with the free version on Linux.
This is a Python script that watches a folder for file changes. Once it sees a new (or changed) media file, it starts transcoding it, using the previously supplied ffmpeg settings.
From source: install hatch, then use hatch run autotranscode and take a look at the available options.
Alternatively, for a global release installation, download the tarball from the release (not the sources!) and run pipx install <tarball>. You can now use autotranscode.
Usage: autotranscode [OPTIONS] DIRECTORY
Watch and transcode all video files in a directory tree automatically.
Options:
--version Show the version and exit.
-s, --suffix TEXT Suffix to add to the encoded files.
[required]
-cv, --video-codec TEXT Video codec to encode into. Input files that
are already supported or match this codec are
never transcoded. [required]
-ca, --audio-codec TEXT Audio codec to encode into. Input files that
are already supported or match this codec are
never transcoded. [required]
--container TEXT Video container to use.
-o, --extra-output-args TEXT Extra ffmpeg arguments to add to each output
file. This is useful for additional output
format options, such as encoder-specific
settings. Use the format 'option=value', and
omit the leading dash. Take care: not all
files will have video and/or audio streams.
-i, --extra-input-args TEXT Extra ffmpeg arguments to add to each input
file. These are usually global ffmpeg options,
such as hardware acceleration. Use the format
'option=value', and omit the leading dash.
--help Show this message and exit.
