VLC Fullscreen freezing videos

[luca87]

In Ubuntu 18.04 distribution I use VLC player to reproduce mp4 videos (1280x720p) in fullscreen and loop mode.
After some videos are correctly reproduced the video freeze, the audio carries on.
I used the --verbose=3 and --avcodec-debug=1 options and I got these log messages.

How can I solve this problem?
thank you!
