simplest video example #2225

Closed mcfiredrill closed 2 years ago

mcfiredrill commented 2 years ago

Describe the bug I'm trying to make the simplest possible video script and get it working.

To Reproduce

v = video.testsrc()                                                                                                                 
output.video(v)

I don't think it could get much simpler than that. :)

Here's the log output

fwiw I've gotten the video.testsrc to work with HLS output, but I'm still not sure what package I need to install to get output.video working.

This is fixed now, thanks for reporting!
