Is this behaviour of VLC normal?
I'm on ubuntu 16.04 unity latest updates installed, I have one of the best Asus gaming laptops in the market, VLC is installed but I never use it.
For the last few months, I wasn't able to shut down my PC, every time I try to do so, the fans start spinning so fast and it hangs, so I just press the shut down button, that problem was only on shutdown, not restart I didn't even bother trying to solve the problem.
Today, while I was working, I noticed the fans doing the same thing that they normally do while shutting down. I ran top noticed 2 vlc instances being run under my username consuming like 122% cpu each, although again I don't use vlc, and I'm not using any program that relies on vlc.
I tried to sudo kill <pid> and sudo killall <pid> and sudo killall vlc but still they weren't killed, that never happened to me before. I killed them from Ubuntu resource monitor, they were killed and the shutdown problem was fixed, and everything went back to normal.
Did that happen to anybody before?

Hi, Lynob, I just updated the script in my answer in a way to be compatible with crontab, that by default works with limited number of environment variables... Now, according to my tests, the script works as it is expected.

If you're interested in finding out why it's happening, you could runps aux | grep " $(echo -n $(pgrep vlc | xargs ps -o ppid | tail -n +2 | tr -d ' ') | sed 's/ / \| /g') "next time it happens. This would find all running instances of VLC, get the parent PIDs for each of them, and then search for the parent PIDs in the output ofps aux. It might help in tracking down the problem.

For the record,sudo kill -9 <pid>would probably have worked where justkilldidn't. The-9means "Kill anything that moves, with extreme prejudice, in the most gruesome way possible". Not much can survive it. Without-9, it's more like "Please die? Please, pretty please with a cherry on top?"

@trysis: Be careful withkill -9, it's dangerous. If for example the application has created a temporary file under/var/lock, it won't be removed. Similarly, buffers won't be flushed, database transactions will not be committed, etc. You could end up with corrupt or missing data if anything was being written anywhere. VLC is probably not doing any of those things, but I would recommend trying to understand the problem before assuming.

BTW, 99% problems I had with VLC hanging and doing other "strange stuff" were due to it trying to use hardware acceleration for video decoding, or using the "wrong" (whatever that may mean) video backend; I'd try to fiddle with that stuff (disable HW acceleration for codecs, try to change video output backend) and see if anything good comes from it.

I'm experiencing similar problem with VLC player. But the difference is I'm using it often. Here is one possible (not fully proofed) workaround for this issue on Ubuntu 16.04 with Unity.
According to this answer we can test whether there is a running application desktop file named vlc or so. If there is no one we can try to kill all VLC's processes. For this purposes create an executable file, named ~/bin/vlc-killer.sh, and add the following lines as its content (here is a reference about the exported envvars):
#!/bin/bash
# Check whether the user is logged-in: if not then exit
if [[ -z "$(pgrep gnome-session -n -U $UID)" ]]; then exit; fi
# Export the current desktop session environment variables
export $(xargs -0 -a "/proc/$(pgrep gnome-session -n -U $UID)/environ")
# Test whether there is any VLC RunningApplicationsDesktopFile
/usr/bin/qdbus org.ayatana.bamf /org/ayatana/bamf/matcher
org.ayatana.bamf.matcher.RunningApplicationsDesktopFiles | grep -q 'vlc'
# If not killall VLC processes
if [[ $? -ne 0 ]]; then /usr/bin/killall vlc; fi
Then open the user's Crontab for edit (crontab -e) and apply the following job (that will execute our script each minute) at the bottom:
* * * * * $HOME/bin/vlc-killer.sh >/dev/null 2>&1

If I'm right this works only when at least one instance ofvlcwas started via the GUI. If you are used to runvlc movie.mpgsolely from the command line (like I am) this will kill thevlcprocess after a minute. However, nice solution and +1 anyway.

Hi, Lynob, I just updated the script in my answer in a way to be compatible with crontab, that by default works with limited number of environment variables... Now, according to my tests, the script works as it is expected.

If you're interested in finding out why it's happening, you could run
ps aux | grep " $(echo -n $(pgrep vlc | xargs ps -o ppid | tail -n +2 | tr -d ' ') | sed 's/ / \| /g') "next time it happens. This would find all running instances of VLC, get the parent PIDs for each of them, and then search for the parent PIDs in the output ofps aux. It might help in tracking down the problem.– anonymoose

For the record,
sudo kill -9 <pid>would probably have worked where justkilldidn't. The-9means "Kill anything that moves, with extreme prejudice, in the most gruesome way possible". Not much can survive it. Without-9, it's more like "Please die? Please, pretty please with a cherry on top?"– trysis

@trysis: Be careful with
kill -9, it's dangerous. If for example the application has created a temporary file under/var/lock, it won't be removed. Similarly, buffers won't be flushed, database transactions will not be committed, etc. You could end up with corrupt or missing data if anything was being written anywhere. VLC is probably not doing any of those things, but I would recommend trying to understand the problem before assuming.– Kevin

BTW, 99% problems I had with VLC hanging and doing other "strange stuff" were due to it trying to use hardware acceleration for video decoding, or using the "wrong" (whatever that may mean) video backend; I'd try to fiddle with that stuff (disable HW acceleration for codecs, try to change video output backend) and see if anything good comes from it.
