The VideoLAN Forums

Good morning,
I haven’t been able to play videos in this format for a year. They appear highly pixelated, dark and with a green predominant that covers large parts of the screen. In short, the video stream is not correctly decoded.

Here is the technical information of the video feed:

Codec : MPEG-H Part2/HEVC (H.265) (hevc)
1920x1024 @ 23,976215 fps
Decoded format : Planar 4:2:0 YUV 10-bit LE
Orientation : top-left
Primary colors: ITU-R BT.709
Chrominance: Left

Hi, do you have sample files that you can share? Can you also post logs?

One of the possibility is that your machine is too slow at decoding it because it uses CPU decoding, and the decoder will drop frames (and potentially corrupt the ones after) if it's too slow.

Good morning,

My computers seem to have a lot of power to decode these streams and even more important ones.

I send you the characteristics of my main machine as well as video files and VLC logs in private message.

Here is the log that only displays errors (I send you the most complete with warnings in private) :
Best regards

Please open Tools -> Messages (set Verbosity to 2) before you start the playback, and then paste the full resulting log here or on Pastebin.com or on Justpaste.it if it's too long.

Also upload a short sample of your original problematic file to WeTransfer.com or Disroot.org and then post the link to the file here.

Hi, you have the motionblur video filter enabled, which will trigger CPU download and reconversion. This is ultra expensive and probably explains why you get this. It should already take a long time to start (~2s)!

Relevant log:
Can you try disabling it? Sorry I don't have any visual procedure ready, but you can at least try to reset preferences if you don't find how there: https://docs.videolan.me/vlc-user/deskt ... references

Hooo YES !
Motionblur was the problem. I don’t know why it was activated on my machines but without it the problem is solved!
Bravo unidan, you’re great.
