Question

Is it possible to pass arguments to ffmpeg directly from youtube-dl cli?

I did some search, and have found one example in the python code level, but I’m wondering if it is possible from youtube-dl cli.

The use case is, for --extract-audio to convert video files to audio-only files, or doing audio-only downloading, it’ll be super if I can increase the audio volume using ffmpeg option on the fly, instead of me doing it again afterwards.

I don’t know if it is even possible, so I’m just asking. thx

@UliGall In your case, ffmpeg IS downloading, not post-processing. You can pass arguments with --external-downloader-args.

FYI. There’s a --hls-prefer-native option to make youtube-dl itself download HLS. However, using --hls-prefer-native and --postprocessor-args will give the same result as downloading with ffmpeg in your case. This is because youtube-dl is passing arguments to ffmpeg after input files.
