Hi. Quite a fun one. A c920 webcam when brought in as NDI source from another vMix instance gives an upside down image. This is easy to correct in the input settings by rotating the image. However if the same input is brought in as a Replay source there is no way to do the same rotate. Other input sources seem fine.

Hi Andrew

I can also confirm that I get the same when using C920 (NDI Camera is upside down) NDI Output does not have the issue.

Regards

James

Of course it's upside-down. You're not in the northern hemisphere. Silly boys.

I'm traveling so I can't test right now, but I don't recall seeing anything like this. NDI Connect is free, so you could download and try it out.

This is a known bug that should be fixed in the next vMix update.
In the mean time try using the C920 with YUY2 or UYVY as the video format as these should work fine.

It's not a burning issue, but vMix refuses to accept those formats returning error " Capture Resolution not supported by this device". It doesn't matter what I set as the resolution same error. If I use the default format or MPJPEG all is well.

In the past I've noted that there's a relationship between the target resolution and the available encoding formats.

You'd expect that for 1080p30, where MJPEG or H264 is absolutely required to get across the USB 2.0 link.

However, it happens at lesser resolutions as well. For example, when almost any resolution <720p only YUY2, MJPEG and H264 are allowed.

The C920 simply won't output 720x486.

Happily, the vMix error message lists all the supported resolutions and encodings.
