I suddenly have lost the ability to change format from 8 bit raw to anything else using the indi_asi_ccd driver with my ZWO CCD ASI178MC. The error message is:

[ERROR] Cannot change format while streaming/recording.

However, it is neither streaming nor recording. Turning streaming on and then off and recording on and then off does not solve the issue.

I tried using the camera with an imaging program that has internal ZWO drivers and no issue. I also tried using PHD2 (Xubuntu 20.04 on Pi4 64 bit mode). When I use the native ZWO driver, all is well. When I switch to the indiserver, it goes back to stuck in 8 bit mode with the error on attempted change.

I have had the camera about a month and it has worked well until last evening. I did download the latest from github/indi and compile/install proir to the error. That may be the issue. If so, was there a recent change to the code?

I had this exact problem a few days ago. It cleared up for me in later builds. When did you last pull from git for your build? I used a pull from last night, with this timestamp: git-20201119133258, and everything worked well for me on both ZWO cameras. I even tried switching from 16 to 8 and back to 16.

A day or two ago...but I will pull one now and compile, then report back.

[SOLVED] Today's git and compile fixed it.

Thanks!

Same is happening for QHY cameras.
