Hello Bandit1983 , related to the creation of avi file : I have written 80 frames of Grayscale(20 R, 20 G1 , 20 G2 , 20 B) after adding all the requierd headers , so now it is running for 4 to 5 sec but with BLANK SCREEN
09:29
Dev__
Is it becoz i have written grayscale . does it support grayscale frames
09:32

Hello se6astien , I wanted to discuss about Control Daemon and its task , I was looking for it and could able to made following conclusion (please point out if i go wrong)
10:42
Dev__
1. Control Daemon controls the parameters of camera tools like image sensor , registors etc , we get and set differnet parameters of camera
10:44
Dev__
2 . we have two methods to communicate with daemon 1 . Web remote 2. Command line interface .
10:45
Dev__
3. at this time only few parameters are set (like analog gain or digital gain) , so we can only question about these
10:46
Bertl
yes, that's about it for now ...
10:46
Dev__
Question :(as given in task) "Move functionality from shell scripts in the firmware to daemon, so it can be called from unified place" , What are these shell scripts for ?
10:47
Bertl
currently all the settings and system configurations are done via shell or python scripts
10:47
Bertl
like for example enabling or disabling certain voltages, configuring and reading out sensors, etc
10:47
Dev__
Sorry Bertl , i have to use web interface for now , as my college wifi have some proxy system which blocks hexchat
10:48
Dev__
but soon i will talk to them (holidays going on)
10:48
Bertl
no problem for me/us
10:51
Dev__
so we wanted to replace all of them(https://github.com/apertus-open-source-cinema/axiom-beta-firmware/tree/master/software/scripts) and made daemon to enable to disable them
10:51
Dev__
if yes , what is the reason
10:51
Dev__
(made daemon enable or disable them )*
10:56
Bertl
well, probably not all of them and/or not all of the tasks the scripts do, but some or more precisely certain parts of the scripts
10:56
Bertl
let me give you an example why this makes sense
10:57
Bertl
let's say we have a script which changes the gain (and actually we have one :)
10:57
Bertl
it does this by setting a number of sensor registers directly
10:57
Bertl
now if you run this script on the commandline, besides the fact that it will not synchronize to the actual image acquisition, it will work just fine and set the values
10:58
Bertl
now let's assume we have a web frontend and the axiom remote connected and all of them want to change the gain
10:59
Bertl
we either end up with a race condition or maybe even a lockup when more than one script/program tries to change the registers
10:59
Bertl
so in a long run, it's way better if there is only one program which makes those changes
11:00
Bertl
and this is where the control daemon comes into play
11:00
Bertl
a script/program wants to know the currently set gain, it simply asks the control daemon
11:00
Bertl
some control program or script wants to set the gain? it contacts the control daemon and asks for a change
11:01
Bertl
does that make sense?
11:02
Dev__
yes Bertl , it surely does , i will try to learn about a particular script (probably analoag or digital gain ) and see how daemon has implemented it , to see how others can be implemented as well
11:03
Dev__
i will update u soon
11:05
Bertl
no problem, please also check with BAndiT1983|away when he's around, he knows what the control daemon does or doesn't do :)
11:06
Dev__
yes Bertl , thanks
