@NIXIN you can use opencv to write the frames into .avi or any other format you want to write.

@RockAndCode said in Video plays fine on the linux device using gst-launch, but fails to play with a Qt application?:

Is there certain eglfs settings that needs to be set when running the Qt based apps on the device?

Can you tell me how and which eglfs settings need to be changed?
I am using nVidia TX1 board.

You might want to check the libqtavi library: https://iondev.ro/qtavi/

It enables Qt based applications to easily save video files in the AVI container format and is available under two licenses: open-source (GPL v. 3.0) and commercial.
