The resulting mp4 had an issue with the metadata in the mp4 video. This payed fine in Chrome but not Firefox. The following shell command was used to convert the mp4 file which fixed the issue.
ffmpeg -i broken_input.mp4 -c copy -movflags +faststart fixed_output.mp4
What this does:
-i broken_input.mp4
: your original file
-c copy
: copies audio and video without re-encoding (lossless)
-movflags +faststart
: rearranges metadata for better browser compatibility (especially for streaming)
