I'm not able to play a video in Firefox. Firefox gives a warning on URL.createObjectURL(video):

Media resource blob could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005)
Details: auto mozilla::SupportChecker::AddMediaFormatChecker(const mozilla::TrackInfo &)::(anonymous class)::operator()() const: Decoder may not have the capability to handle the requested video format with YUV444 chroma subsampling.

I also tried the video converter package convert-video but the same issue occurred.

Firefox won't support that video's format, see https://bugzilla.mozilla/show_bug.cgi?id=1368063.

The suggested solution is to create the video using ffmpeg's -pix_fmt yuv420p switch.
