Build 2737, Device does not support video standard

[zoneminder]

I will apply your patch for non-ffmpeg conversions. Is that last post the entirety of it?

Essentially yes.

Below is the same update for the latest 1.24 official release. This also includes an additional tweak for the unknown video standard problem I get with my uvc cams. The 2740 tweaks didn't quite wrap all the impacted calls.

Code: Select all

Thanks. The first section I have done slightly differently but I think it does the same thing. Ie ignore unknown standards if none is set.
