I've created this app for automizing of my podcast creation process.
Vakhloader could get you the last episode (audio track from the last video on the youtube channel) or the chosen one.
To get the last episode, use the next command:
python vakhloader.py --api-key $your_youtube_api_key --channel-id $your_youtube_channel_id --local-storage-path $target_location_for_the_track
To get the chosen episode, use the next command:
python vakhloader.py --api-key $your_youtube_api_key --channel-id $your_youtube_channel_id --local-storage-path $target_location_for_the_track --episode-number 25
