Add audio files to already downloaded videos.

[anweshknayak]

Actually I downloaded the DASH manifest video files only . I had not checked before it contains only the video output without the audio. Is there any way I can download audio files and merge them to the already downloaded video files ?

That's not supported, but on the second run something like [download] Destination: <title>.f137.mp4 will be printed and you can do the following:

1. Stop youtube-dl
2. Rename the downloaded file to <title>.f137.mp4 (it may be something different to f137)
3. Run youtube-dl again, the video won't be redownloaded
