INDI Library v1.7.6 Released. (27 Feb 2019)

First release of 2019 comes with quite a few new drivers across the board along with significant performance improvements to INDI camera and live streaming performance. Many drivers received significant updates to improve performance & stability, while a few were re-written from scratch to be in line with INDI standards. Here are some of the highlights:

canon dslr banding artefact after upgrade to the stable version was created by alacant

Hi everyone
I took the update and now there is an artefact across the top of the downloaded image. If I reset the frame values in the indi control panel, the artefact disappears and all is normal but the setting does not stick and the artefact reappears upon the next download.

Tried also with the gphoto driver: same, but the artefact remains despite resetting the frame sizes.

Is there any way I can revert to where I was before the update or any fix available for this?
TIA

Can you clear the DSLR config and then when you enter the value again, you enter the 5208x3476

What appears to be happening is when the DSLR was first detected, you entered 5184x3456, so the driver always crops to this value. If you clear the config and enter the value above, the value should stick.

Hi
Still unreliable...

I cleared the dslr config and entered the new values of 5208x3476 with 4.30x4.30 for the pixel size. It starts correctly without the artefact for a few exposures at 5208x3476 but the artefact returns as it reverts to 5184x3456.

My database is owned by me:
-rw-rw-r-- 1 steve steve 98304 Mar 9 23:33 userdb.sqlite
and I start indi via ekos as the same user.

logs: drive.google.com/open?id=1TFSYd9DSTgEyy7dDGSLzvIL4st1kXNG2

The file sizes
without artefact 5208x3476:
-rw-rw-r-- 1 steve steve 36213120 Mar 9 20:53 Light_003.fits
with artefact 5184x3456:
-rw-rw-r-- 1 steve steve 35838720 Mar 9 23:20 Light_036.fits

I believe 5184x3456 is correct for the imaging area of the canon 700d with 5208x3476 the whole chip including non imaging pixels. Did this change with the upgrade? We have always dealt with te smller size before without problem.

How can I make the new value stick?
Thanks.


EDIT:
Jasem, could this be the reason? There are 4 entries for dslr:

Hi
I think I found the problem; at least the values are sticking now.
Clearing the dslr configuration does not clear other values from the database. Instead, it adds another record to those already existing.
Please see the edit to the post above; I cleared the first 3 entries, leaving only the 5208x3476. Now the values stick.
What I'm not sure about is the entry '9' for the field 'Filter' in record number 4. Should I leave this at 9?
TIA,
Steve

Ahggh, another gotcha. It's also in the .esl files, so the <Frame> section needs changing too:
<Frame>
<X>0</X>
<Y>0</Y>
<W>5208</W>
<H>3476</H>
</Frame>
Slowly getting there:)
