It looks like VLC throws an error:

Any updates?

Sorry no. I've been (and still am) busy. I can reproduce & I will get round to it, hopefully within the next week or so.

Problem found. The fact it failed in omxplayer too pointed the finger at the firmware, and indeed it was a firmware issue.

Your particular stream uses multiple 0xFF padding bytes between JPEG markers, and the decoder wasn't allowing for this and threw errors. I'm about to pusha patch internally, so it should appear via rpi-update at some point.

Thank you, 6by9!
Any idea if this firmware fix will also solve issue #9 ?

Totally unrelated. HEVC doesn't go through the firmware at all

Works perfectly!
Please close this issue.
