I am using Firefox Browser 92.0 (64 bit) for Ubuntu Canonical 1.0 I am running Ubuntu on ACER laptop uname -a Linux aneesa-Aspire-5733Z 5.11.0-34-generic #36~20.04.1-Ubuntu SMP Fri Aug 27 08:06:32 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

When I try to open an MP4 video, it gives wrong message 'Video can't be played because the file is corrupt' whereas it plays absolutely fine on Google Chrome. Both screenshots attached.

I provide this link to my 1 minute video. https://maktab.net.au/ZahidMenu.mp4

ffmpeg is installed. I created my video using it.

Please help me. Thank you

Please read https://bugzilla.mozilla.org/show_bug.cgi?id=YUV444

For future reference for people who stumble upon this Firefox bug, the solution is to add "-pix_fmt yuv420p" in your ffmpeg command line.

Thank you. I read the entire link that you sent. I struggled trying many many different things that I read which were supposed to work but did not. I think that ffmpeg is under development and constantly changing. And that the documentation states aspirational goals.

So I decided to use OLD reliable software. My solution: (a) I copied my 1 PNG image and 1 MP3 music files to my old desktop running Windows XP (not connected to Internet) . (b) I used Windows MovieMaker software to create a 1-minute WMV video (c) I copied my 1 1-minute WMV video over to my Ubuntu desktop (d) I used https://www.freeconvert.com/ to convert my WMV video to MP4.

The resulting MP4 video works fine on Mozilla Firefox, Google Chrome, Apple Safari and Ubuntu Videos. You can view it at: https://maktab.net.au/Menu.mp4

Thank you for trying to help ! I appreciate your time and effort. Feel free to use my video to fix the bug.
