I am trying to record a Meet chat (from a google drive) by OBS Studio (31.0.3 - 64bit).
Issue is that I am unable to forward or skip through the recording.
I look at it by Totem (Videos). If I try to move forward the Totem's progress bar, either it idles for a long time, or just halts. It is not better for the .mp4 file I got by remux.
I am on a Fedora 41 and I tried to record both as a user and as the superuser, and both Wayland and Plasma X11.
On the same machine, if I record the same source by Vokoscreen 4.4.7 (Plasma-X11), fast forward and rewind are fine.
I tried to check both outputs by mediainfo (see below), but I am not sure what I should look for.
I appreciate your help. Cheers
