Hi Nicolas,
Thank you for taking the time to test this out. When you mentioned this, we also tried this on VLC v2.0.3, v2.0.5 and v2.0.8 on windows and linux platforms. And we saw different behaviour for different versions of VLC, some displayed blank screen at first, some displayed gibberish video. But all of them after a few seconds (2 to 7 seconds) played normally.
So I think the issue here, is that the keyframe(s) are not yet received by the VLC player (or for worst case scenario, it was lost…).
Hope this clarify things up :-)” />
Cheers,
IC
