I'm on LE10 nightly, that I update daily, running off a Raspberry Pi 4 4 GB.
I am trying to play an H.264+AAC in an MP4 container, and it fails, showing the rotating wheel, no message)
Here is a pastekodi with debug on: http://ix.io/2UJp
If I reencode the audio track only, same refusal to play. If I reencode the video track, it plays. So the problem is with the video.
Any other H.264 videos I have play without any issue.
The same video plays without issue on my MacBook Pro using Kodi 19.
Here is a debug log from the Mac, if it helps: Ubuntu Pastebin
I can provide a sample file. I can provide any other needed info or testing.
Thanks for your help!
