Summary: noticed that when using qhy268m at high framerate to produce a ser file this is written with 8 bit sampling instead of 16

STEPS TO REPRODUCE
1. running the streaming capture
2. obtain a ser file
3. 

OBSERVED RESULT
the ser file is converted is a sequence of fits frames but in both cases files are sampled at 8 bit

EXPECTED RESULT
16 bit

ADDITIONAL INFORMATION
I Jasem, while waiting for the next version of kstars for Mac I'm trying to run it together with a Vbox virtual machine ubuntu. I noticed what is described above (8bit instead of 16 as ser file result). Is that a known behavior? I chosed qhy268 for its high framerate  and sampling to obtain the best in speckle interferometry data and that would be a pity... just in case, do you think could be fixed in the future? thank you so much in any case

This is an INDI issue, not KStars. At any rate, did you happen to have the streaming on at the same time? Streaming downscales to 8 bit first. If you just record, it should be 16bit.

Hi Jasem,
first of all I'm sorry to have reported in the wrong place... it was just because I was running from the Ekos panel but .. once again... sorry.
I tried to capture the ser file both from the Ekos interface button and directly from the Indi tab panel straight.
And in this latter case I tried both: with streaming off and streaming on.
Also I noticed that almost all the time it looks like as it fails to close  the streaming recording job because if you try to repeat the recording (or change other settings) the log message says the the recording device is busy (something like that) and the only way is to disconnect and restart.
Thank you
Luca

ps: (the same as above directly on the Mac)
