Support for downloading different audio types?

[nednoodlehead]

It would be nice if we had support for downloading audio via best_audio() could have some option to return the video as a wav or mp3 version. Not sure if this is some limitation with the YouTube Api or not, but it would be really nice. And I believe pytube downloads as mp3 by default, so it must be possible.

I have been trying to use the files with other rust audio libraries like symphonia and there is no support for the opus codec. Which makes using symphonia and rustube in the same project sort of complicated.

Hey @nednoodlehead, thanks for the feedback and sorry for the late answer.

If I'm not mistaken, pytube uses ffmpeg for doing that. At this point in time rustube does not do anything similar. It just provides raw access to the individual streams YouTube offers.

You can however try to filter out the types of audio formats you don't like:

let video: Video;
let audio_stream: &Stream = video
    .streams()
    .iter()
    .filter(|stream| stream.includes_audio_track && !stream.includes_video_track) // Get only the audio only streams
    .filter(|stream| stream.mime.subtype() == "mpeg") // Filter for MPEG streams (or whatever you're looking for)
    .max_by_key(|stream| stream.bitrate) // Get the best quality stream of all remaining
    .expect("No streams match the filters");

For converting audio streams of one type to another, you can always fall back to ffmpeg. I don't know a ton about it though, so I cannot help you there.
