[Elphel-support] compressor state

[Janz, Scott J. (GSFC-6133)]

Oleg,

Thanks for the testing. I am now setting the maximum exposure consistent with the frame rate (~40 ms for 24 fps) and the camera has been stable under all lighting conditions. Does anyone have sensitivity measurements (lux vs. gain) for the 353's using an f/4 lens in both color and b/w mode?

thanks,

-scott

Andreas, Scott,

Did Andrey advice about AUTOEXP_EXP_MAX help?

I've just tried to reproduce the problem with parameters from Scott. The difference is the script that execs snapfull.php is running on the camera and it uploads images to my pc's nfs folder. I'm getting mplayer crashes only with unlimited autoexposure and after that the camera can be recovered and the image getting script keeps working.

Andreas,
Did you mean the stereocam working in one of its modes?

Andreas,

You may need to set the limit for autoexposure (AUTOEXP_EXP_MAX) so the exposure time will not exceed the frame period. The videostream is not designed to have variable frame rate, and if autoexposure sets time longer than 1/fps - the frame rate will have to drop lower.
