MP4 encoded won't play in mobile

[markginter31]

When I encode in MP4 - the video will play in all desktop browsers, but will not play in mobile. When I encode in WEBM - the video will play on both desktop and mobile.

To Reproduce

1. enocode in MP4 - won't play
2. encode in WEBM - will play

Expected behavior MP4 will play in both desktop and mobile

Error Logs No errors appear in logs. Running the latest version.

Desktop (please complete the following information): Desktop -- Fedora 40 Firefox/Chrome Mobile - Samsung S20 - Samsung Browser / Chrome

I'm not sure where to look to find why the MP4 doesn't play but the WEBM does.

What exactly option are you using to encode?

automatic MP4 or are you forcing LOW, HD and SD?

[markginter31]

First I noticed it wouldn't work when all the resolutions were checked in the encoder (I assume that's automatic) Then I only chose 480, 720, and 1080 and MP4 still wouldn't work.

Both times I got MP4's unplayable in mobile but playable on desktop.

Is there a way in the mobile browser to check for errors?

I don't have access to an iPhone to try.

I made those changes but still can't play mp4s.

You can see my test runs at https://video.oakhillcog.info

I'm really stumped.

Also - the first couple of videos were fine (the ones at the beach). It's the recent ones I tried uploading that aren't working.

Just tested this one on iPhone and works fine

I am not 100%, can you please try longer videos 1 minute or more?

[markginter31]

Just posted a 2 minute video. MP4 won't work. What's really weird is that those sunrise videos uploaded and converted fine a month ago.... But any of the newer videos don't (yet) 😀

Weird,

I uploaded your video and I got the same problem here

https://demo.avideo.com/video/436/mp4-test-on-mobile

also I upload a different MP4 and there is no issue

https://demo.avideo.com/video/438/mp4-test-2

so the issue is in the source file, there is probably something needs to be added on FFMPEG, but I am not sure what is in your mp4 video that is different from mine

If you want to inspect you can use those 2 files

your file that fail to play on mobile

I figured it out. At some point I set an option in my phone camera to HDR10+ once these videos were uploaded and converted the video codec showed as H.264 (High Profile 10) with a frame rate of 120. The videos that work showed video codec of H.264 (High Profile) with a frame rate of 24

I turned off the HDR10+ setting and now videos upload and encode fine. Sorry for the hassle. It was my own fault.
