Mp4 Stream Recording Doesn't Include Audio

[mahzaib]

I am trying to use command-line VLAN to record a streaming video; however, the mp4 recordings do not contain any audio.

I am running MacOS 11.0.1 (Big Sur)

This is the command that I am typing (although I have tried numerous variations to no avail):
/Applications/VLC.app/Contents/MacOS/VLC --run-time=5 -vvv --sout '#transcode{vcodec=mp4v,acodec=mp4a,vb=800,ab=128}:file{dst=/Users/marjoram/Downloads/vlc-output-4.mp4}' 'https://www.youtube.com/watch?v=9lN2X2QGjNQ'

I have tried different sampling rates & audio / video codecs, but each time I am able to get an mp4 file - however, it doesn't contain audio.


GUI Issues (entirely separate issue - however, being that the GUI didn't work, I moved to the command line)
Additionally, I started with the GUI; however, the file was either always empty or it contained just a few bytes.
Repo Steps in GUI:
- Select File->Open Network
- Provide URL
- Select Stream Output checkbox
- Select Settings box
- Select Display the stream locally
- Select File & provide file location - file extension is 'mp4'
- Select Encapsulation Method -> Raw (I've similarly tried MPEG 4)

Additionally, I've tried dumping raw (I get an error for this) & modifying video and audio transcoding options. None of which result in the stream being converted to the mp4 file.
