Playback drops most frames of a fragmented MP4 encoded with ffmpeg

The attached video file cannot be played. Only the first frame or sometimes a few frames are displayed, and all subsequent frames are dropped until the video is stopping at the end (with the last frame rendered).

The hardware is reasonable fast (Intel Core i7) for playing videos in general and the background load is at its minimum. I removed ~/.config/vlc and ~/.cache/vlc and run vlc --reset-config as well.

Do you know why this is happening? Can you point me into the direction where I could verify if the encoded video itself is broken in some way or VLC got a bug in decoding this video file, where other players like MPlayer do not have any trouble with its playback.

Thank you very much in advance and in the following see the detailed output of vlc and ffprobe.

Fragmented mp4 file doesn't play back video properly (audio works) (#20369)

The difference is I get a visible video. VLC is able to render a few frames, but dropping most of them. Sound I can not verify, because the software encoding this video does not encode any sound.
