Except MJPG any codec doesn't work

using videowriter, tried to save MATs into video file(like ‘.avi’ 'mp4 etc)

only I could make .avi with MJPG codec.

should I install additional things to use other codec like h264?

i’m using ubuntu os, QT environment

opencv version ? self built ?
output of cout << getBuildInformation(); ? (there’s a VideoIO section)

this is indeed the only ‘builtin’ codec,
anything else is handled from ffmpeg / gstreamer

…then I must build it again…?
