indi_sv305_ccd: Native file format can be selected, but the driver does not support Native.

[jctk]

Describe the bug
"Native" format can be selected in the Ekos camera module.
When Native format is selected and a picture is taken, the camera terminates abnormally the second time.

To Reproduce

1. Select Native format in the Ekos camera module.
2. Capture a shot with the "Capture a perview" button.
3. Fits viewer is not displayed.
4. Capture a shot with the "Capture a perview" button again.
5. indi_sv305_ccd and KStars terminates abnormally.

Expected behavior
"Native" format does not appear as an option. Or, it is possible to shoot in "Native" format.

This issue was reproduced in indi_asi_ccd as well.

Hi, @knro

I don't know what 'Native' format is.
Is the data output by the Camera driver directly into a file ?

[knro]

Yes it's how you encode the data. Native means whatever the driver deems. For some DSLR cameras, it captures in JPG and you can encode it as either FITS or native JPG and send as-is. For ASI and SV cameras, there is no native, native would be just raw data which cannot be read.

We should probably add a method to remove "Native" from the available selections for some drivers.

A simple trick now that might EncodeFormatSP.nsp = 1 in UpdateProperties()

Yes, I agree with you.

I will try sonn it.
Thanks !
