Details
The following video plays with only sound or only video in Firefox on Android 5 and 6 devices:
Curiously, if played directly in a tab, no audio plays, only video. Whereas if played via a <video> tag, no video plays, only audio.
This was reported at https://webcompat.com/issues/24198, and there is some addition info presented on that issue which may be of use.

Maybe a codec profile/level issue? John, any ideas?

Actually, the same symptoms are happening on Windows 10 for the reporter of the webcompat.com issue, so this might be more widespread than Android.

Tried the link and got a 403 response -- "URL signature expired", so I signed up to IG and checked several videos listed there with both Android 6 and 9. Unfortunately, all play just fine. I wasn't an IG user and have no clue how to get to the "stories video" mentioned in the original webcompat bug...
Thomas, could you please help provide another link that is still valid or instructions that lead to the broken video? Thanks a lot!

Sure, I backed up a copy of the 2.1mb video (just in case) here: https://thomas.tanrei.ca/moz/sample.mp4

Thank you, Thomas.
Your MP4 video plays in Nightly on my Pixel 3 (Android 9), Lenovo Phab 2 Pro (Android 6), and Window 10 PC so I am unable to see what's wrong. If it's a codec problem, there might be some error message in the Android log. Could you please help reproduce the issue on your phone, capture the log with adb logcat, and upload it? Thanks a lot.

How bizarre... I just tried again, and my tablet is playing that video just fine. I'll ask the user on the webcompat.com bug to see if it works for them, and if so, to generate another link.

However, it appears that my link is still causing issues for the original reporter of the issue on Windows 7, as per https://webcompat.com/issues/24198#issuecomment-456676344
They're receiving a message that the file is corrupt in Firefox 56, while only audio plays in the nightly build. They're wondering if maybe openH264 plugin is related, and if it might be, how to make the plugin reinstall/refresh.

I don't have a Win7 machine to check the problem right now, but AFAIK OpenH264 is only used for WebRTC and not for video playback. Jean-Yves, is it correct?

I don't think there's much we can do here as we rely on the system's h264 decoder and we have no control over it.
Can reproduce the problem on Windows 7. Works fine with Win10
