elp camera kinda like a bug
elp stereo cameras never work correctly unless fourcc('M', 'J', 'P', 'G')); is used so how could i do that in the GUI Windows ?
and by any chance if anyone got code example for stereo camera please share it
CameraStereoVideo driver uses opencv's VideoCapture to read from USB cameras (when single camera is used, it assumes it is a side-by-side stereo stream). It opens the camera here: https://github.com/introlab/rtabmap/blob/465ea85d91d8340ccc961f5997333e7e16c8258a/corelib/src/camera/CameraStereoVideo.cpp#L132
If opencv support fourcc('M', 'J', 'P', 'G') , you may check how to do it before it opens the camera and adjust the code above.
@matlabbe yes its side by side i will try to work with it , by the way they should add it to the GUI so how to report that problem ?
about opencv yes it support fourcc('M', 'J', 'P', 'G') i think from 4.4.0 all work the same way same API if i am not mistaken
and thank you a lot for answering me <3
the way they should add it to the GUI so how to report that problem
do you mean adding fourcc('M', 'J', 'P', 'G') option under Preferences->Source and stereo video driver?
i meant inside the GUI when i pick usb camera this option should be there , and the arrange is important fourcc('M', 'J', 'P', 'G')
for example
cap width and hight fourcc('M', 'J', 'P', 'G') cap fps
this will never work , i test this with opencv 4.4.0 , 4.8.1 and some versions between them
the correct way the fourcc('M', 'J', 'P', 'G') must be the last thing
@matlabbe and thanks so much for fast respond and being so kind with a new commers <3
If you can confirm that you can get images doing what you suggest with CameraStereoVideo driver (even by hard coding it and running the main app for a quick test), we could add indeed the option to GUI.
