Hi,
I just upgraded my docker based motion system from 4.3.1 to 4.5.0. Since then
some of the videos shows a wrong duration. Attached is an example of the
mediainfo output of a captured video, which is in reality about 50 seconds long:

Codec configuration box : avcC
I did not change any configuration parameter from 4.3.1 to 4.5.0. When playing
the video (almost) the last frame is displayed for the remaining time. Any idea?
Many thanks for your help!
