streams not working due to "invalid arguments"

[spamwax]

I have V3 and copied the latest version of go2rtc to the bin folder. The go2rtc page works and shows me the stream options. (Before using the updated go2rtc, I was also getting errors like streams: exec: exit status 1)

However, none of the links work and these are the error/log messages:

The log page of go2rtc also shows [exec] /dev/video1: Invalid argument. However inspecting the SD card, I see bunch of videos recorded!

You using outdated ffmpeg. Go2rtc requires ffmpeg 5+.

I see, thanks for the hint. since I was using go2rtc as part of https://github.com/gtxaspec/wz_mini_hacks, I did not have muck control over the version of the ffmpeg. Also the Wyze camera I am using had a firmware unsupported by z_mini_hacks.
