Hi there.

Can you tell me if I'm doing something wrong here when extracting audio? This command generates an m4a file that plays in VLC. When I drag the file into iTunes, it shows sample rate, profile, stereo channels, and that it is AAC, but it doesn't show duration or bit rate. It also won't play.

Thanks.

YouTube serves m4a files with a weird header that iTunes does not support. youtube-dl 2015.01.23.4 and newer will automatically correct the header of the m4a file if ffmpeg is present on the system. I am therefore closing this issue. See our FAQ if you need help updating. Thank you for the report!
