Public bug reported:
If vlc is trying to load a file, or multiple files that don't exist, CPU
usage will increase while many error messages announcing this problem
will appear. This can lead to a freeze and crash, and pressing 'hide
future errors' might not help since CPU usage will still be high.
Sometimes it's possible to fix this by quickly pressing the stop button,
but this doesn't always work.
Desired result: if a full loop of a playlist, or always if set to loop a
single item, results in no items being found, VLC should wait for a bit
before trying again. Pressing spacebar or any other key that normally
pauses the video (as opposed to stopping it) should also cause it to
stop trying to load more items.
It doesn't seem to be easy to cause VLC to actually lock up... ok in
fact, what just happened was that by trying to play a file that didn't
exist several times, after I stopped trying my CPU usage was high
despite that VLC was supposedly not trying to open anything as no error
messages were showing up. Pressing the stop button repeatedly did not
change this, despite that pressing it caused it to change to the 'button
pressed' animation.
Then after playing a video and then stopping it, CPU usage was back to
0.
Locking up might only seem to happen when VLC has been trying to open
non-existent files for a few seconds too long; the 'non-responsive' test
in Compiz that causes unresponsive windows to darken can activate. Just
now, with vlc running at 100% of a CPU despite that no error messages
were turning up, I tried starting it (to play a non-existent file) and
then immediately stopping it, yet despite continually trying to click on
the stop button, it took probably 12 seconds to stop.
