Strange. This would mean that QT AV (the internal video player of XnView MP) isn't completely independent from the platform. :shock:

Short or not - the example.mp4 should play. It does play in Windows Media Player but not in XnView MP.

Videos have a delay sometimes, after more testing with the example.mp4, sometimes it just blinks, first there's just a black screen and sound, then picture blinks. That's why I asked for testing longer mp4 videos.

Perhaps it's another bug, black screen / late picture when playing videos in browser video.

OK, so I tested few more files, same delay, even worse, 2-5 seconds of black screen, sometimes only, mp4 and mkv files only, avi looks OK. I will be testing more tomorrow.

There's just a black screen (preview or viewer) and no video and no sound in browser/fullscreen/viewer mode. Looks like the internal player cannot handle MP4 files.

:arrow: Reproduced
The mp4 files can be played without problem here, which windows do you use?
