--extract-audio and skipping video file download

[orschiro]

Hello,

By default --extract-audio erases the video file. That is, the next time using youtube-dl with --extract-audio again grabs the video file to convert it although it already exists as audio file.

Can you think of a way to implement a check procedure that skips to download the video file if the corresponding audio file already exists without actually keeping the corresponding video file?

Regards

Robert

This is entirely untested, but you could try changing the lines starting from line 4220 (a0432a1e80 revision) to

new_path = prefix + sep + extension
if os.path.exists(new_path):
    return None

For it to be implemented as an actual feature a decision would need to be made if the default behavior for youtube-dl should be to overwrite existing files or rather skip them and how to optionally tell it to do one thing or the other.

Thanks for your suggestion. I changed the code but it still downloads the video.

Steps to reproduce.

.\youtube-dl-extract-audio.py -cit --extract-audio http://www.youtube.com/watch?v=oRhedPZrRqc

First time it downloads the video and uses ffmpeg to create the file A_very_short_video_about_farting-oRhedPZrRqc.aac such as expected.

Again I run .\youtube-dl-extract-audio.py -cit --extract-audio http://www.youtube.com/watch?v=oRhedPZrRqc

which gives me [download] Destination: A_very_short_video_about_farting-oRhedPZrRqc.flv.

Any new comments on this?

rename the downloaded and converted files to have .m4a extension and youtube-dl will skip them.
