Most of them were .mp4 videos downloaded from Tik Tok with yt-dlp (https://github.com/yt-dlp/yt-dlp) or by right-clicking and using the 'Save as' dialog.
Here's one example: https://v16-webapp.tiktok.com/150af96e4903dde52283b7197631cd1e/62a10462/video/tos/useast2a/tos- useast2a-pve-0068/861748d6c58c4c4a8b0808e153c5d1f6/?a=1988&ch=0&cr=0&dr=0&lr=tiktok_m&cd=0%7C0%7C1%7C0&cv=1&br=1602&bt=801&btag=80000&cs=0&ds=3&ft=eXd.6HAzMyq8ZACuawe2N5Uoyl7Gb&mime_type=video_mp4&qs=0&rc=NmdmO2RkM2U2NzM4NDQ2OkBpamQ3cjY6ZjZrZDMzNzczM0BeMGBfNDYyX2IxMl8tX2BgYSNsZmgxcjRfLWJgLS1kMTZzcw%3D%3D&l=202206081419310102230981511D31941C -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to totem in Ubuntu. https://bugs.launchpad.net/bugs/1975890 Title: mp4 video gets stuck in a frame, like it's paused Status in totem package in Ubuntu: Incomplete Bug description: The video stops playing at a certain random frame, like it's been paused. You can drag the range control and move forwards and backwards and the frame will change as expected, but toggling play/pause does nothing. I can only reproduce this on Ubuntu 22.04. On Debian 11 it works as expected.
