Loading MOV file cause system freeze [Ubuntu Mate 19.04] [solved]

Postby Toxidious » 01 May 2019 21:42

Hi.

I'm currently trying to use the version of VLC that shipped along with Ubuntu on install, that is version 3.0.6.
I run an old computer and two screens.

After installing Ubuntu I also installed the ffmpeg package using Synaptic Package manager. ffmpeg version 4.1.1-1

Currently connected to the computer is a DOD LS460W camera. (path to where images are located: /media/toxuser/14D6-D328/CARDV/MOVIE)

Following actions will make the whole system to freeze (mouse pointer can be moved, but nothing is clickable)

* Opening folder location (/media/toxuser/14D6-D328/CARDV/MOVIE)
* Opening any .MOV file in VLC.

Seems it hangs in the very moment VLC is supposed to start reading a video file.

[edit]
I now found an MKV file to try to play (Both .MOV file and .MKV resolutions is 1920px wide HD) and it seemingly started playing, but after ~3 seconds it also hang and caused a full system freeze.

I also tried to change display settings so that the screens are mirrored, but that had zero effect.

Turned out that also opening smaller video files with lower resolutions caused VLC to freeze the whole system.
I was able to use Avidemux to encode the first MOV-file into a mkv video with lower resolution.

Anyway - I did some searching on web for that problem, and turned out somebody mentioned changing the output to X11 in VLC settings.
So I did - and guess what? Problem solved - I can watch seemingly all kind of video files without system hangs now, even on this old setup (was an ok gaming rig at it's time when first built)

Just wonder - when video output is set to "Automatic" - where does VLC try to put the video stream at ?
