Fetch audio and video without muxing

[sleepycatcoding]

Actually I found a way to accomplish this by using audio_only() and video_only(), but this requires two requests to the manifest file. I do not know if reqwest caches requests to the same file.

You can use DashDownloader::new(url).keep_audio().keep_video(). This doesn't in fact disable the muxing step but will keep the audio and video as separate files (assuming they are separate content streams).

If I were to use keep_audio() and keep_video(), is there a way to fetch paths to the files?

EDIT:

Seems the paths are only printed to stdout.

Indeed, there's no API to retrieve that information. Perhaps it would be better to change the interface to something like keep_audio_as(audio-pathname) .
