Bug Report: [Camera Control] Video gain adjusts value but not the actual gain (on BMD Micro Studio G1)

Observed Behavior

Hi!

This is a weird one: When setting video gain, I see the value change reflected in the ATEM Software Control, but the actual gain in the camera (BMD Micro Studio G1) does not change. If I change the gain directly from ATEM Software Control, it does work.

The Micro Studio G1 has limited gain steps (increments of 6), maybe this is related.

We also have Micro Studio G2s (the new generation) and for those it does work fine and as expected (nice, btw 🙏 ).

Expected Behavior

So, after executing the code below the gain value of camera 2 is set to 12 on the ATEM side but the change appears to be not sent to the camera. Performing the same change in ATEM Software Control is sent to the camera. Potentially, ATEM Software Control could be sending different commands than this package?

  const commandSender = new AtemCameraControlDirectCommandSender(myAtem)

  commandSender.videoGain(2, 12)

Version

3.5.0 / camera control 0.3.0

Severity / Impact

No response

This might be better to open against https://github.com/Julusian/atem-connection-camera-control, as the camera control portion is a related but not the same project as here.

I only have access to the Micro Studio G2, so all my testing has been done with that. I was expecting that other models should work fine with that, but it is possible that older cameras use a slightly different protocol. From memory the docs do include some differences based on firmware version, but not any from the past few years.

If you are able to provide a wireshark capture of you making the change from the atem software, that would be the best way to try and figure out what we are doing wrong.

My bad! Opened a new issue over there and included two captures.
