MJPG http stream digest authentication issue

Description

We are trying to connect to our IP camera using libvlc (Android & Desktop) to stream the MJPG stream from our AXIS camera to our Android device. We get a 401 Unauthorized even though the credentials are correct & this works perfectly in the browser.

Expected behavior

Connect with the camera and see the MJPEG stream.

Actual behavior

Connect with the camera and receiving an 401 Unauthorized in the logs.

Steps to reproduce

1. Open the VLC app
2. Go to More - New stream
3. Add the stream to the url (LAN - http://192.168.0.160/mjpg/video.mjpg)
4. Enter credentials in the dialog
5. Black screen & error in logs

More information

Setting password type to:

• Encrypted & unencrypted - Stream does not work
• Encrypted only - uses digest, stream does not work
• Unencrypted only - uses basic, stream works
