Thanks Tony. It seems that command is just a wrapper setting up the environment variables documented in the CLI docs already.
However, with the latest version (3.3.6.0.b) it outputs the oauth URL in the terminal, and I was able to complete the login with a bit of port forwarding and a desktop that had a browser. So I now have a valid auth.tpz file and am able to use the models via ffmpeg without the watermark. Thx for pointing me in the right direction.
As to the original Ask, note that I’m running the software from a headless machine with no GUI, so opening a browser from that machine is impossible.
The CLI documentation claims that one should be able to provide the credentials (userid + password) as command line arguments to the login program, or the wrapper script videoaiBETA-login. However that doesn’t seem to work.
Steps for Logging In
If needed, invoke the command line login program:
/login 'username' 'password'
Any idea why this isn’t working?
