A sample file is available in this thread:
https://forum.videolan.org/viewtopic.php?f=14&t=163699

and yes, I can reproduce the issue while it's playing fine with other players including FFplay.

Thats weird. Are you using default vlc settings?
I have added another twitter file with issues in my original thread. Could you see if it also plays normally for you?

Maybe because of this:

Code: Select all

Codec ID : iso5 (iso6/mp41)

Code: Select all

mp4 debug: unrecognized major media specification (iso5).

If I simply remux the file with FFmpeg I'm getting this:

Code: Select all

Codec ID : isom (isom/iso2/avc1/mp41)

and then it's playing fine with VLC.

Typical "I don't give a f*** about the MP4 specs"

The audio is not interleaved in the fragmented MP4, but only arrives in the LATEST fragment.
That shouldn't be playable.

Well, as a matter of fact it's playable with any other player I've tried, including FFplay which is not throwing any error message at all:

Exactly.
How do all other players or even browsers play those files without any issues?
