[🐛 Bug]: mp4 videos recorded with selenium/video container are not skippable when watched in the browser

[bischoffdev]

Description

We use the selenium/video recorder to record browser videos. These are then stored in a GCP bucket and embedded into our html test report. I noticed that you cannot skip forward.

This also applies when the video content is fully loaded and in the browser cache. Even when opened in a new tab and using native browser controls, the same issue is there.

Only when downloading and using a player like VLC, it behaves like it should since VLC fixes this. With our previous grid solution, this was not an issue.

Is there a way to change the video format so this does not occur?

I'm moving this issue to the docker-selenium repo, since that is where the video recording code lives.

arg.. I don't have access to move it. @VietND96, can you transfer this issue?

Hi @bischoffdev, I believe something needs to be dealt with the codec of output recording.
Might I know a few details on your previous grid solution? Did you use selenium/video also? or something else, what is output of video format, how it get recorded, ffmpeg command and arguments used there?
