The VideoLAN Forums

Figured I'd start a new thread since other threads have suggested posting log files trying to track down this problem with VLC pausing/freezing under Yosemite that seems to be affecting some users.

Downloaded the newest nightly build of 2.2 (have seen this with 3.0 nightly builds as well). vlc-2.2.0-x86_64-20141104-0312

Enabled logging in the preferences and also enabled logging via the command line -v command. I put lines starting with ">>>Opened" to indicate when I opened two videos. Please note the two videos I tried open and play fine in MPlayer OSX Extended, Quicktime Player, and Mac Media Player.


First the VLC-log.txt:

Any ideas?

And why is VLC trying to find spottily? I did try installing Spotify after seeing this error, but it didn't make any difference.

I think I found the cause...

After thinking about the Spotify references in the logs, I combed through all the preferences and found the 'Control external music players' setting was set to 'Pause iTunes /Spotify'. Eureka!

Now I didn't have Spotify installed until I tried installing it after seeing the errors in the log, so I doubt that was the problem. So I turned this setting to 'Do Nothing' and POOF! My hanging pauses stopped happening. If I turn it back to 'Pause iTunes /Spotify' and close iTunes, the problem doesn't occur.

So maybe VLC has an issue with pausing iTunes 12.0.1? Had 11.4 before the Yosemite upgrade.

I'll leave it off and add this to my bug report. Still may be a bug in VLC in regards to it pausing iTunes somewhere.

Glad I finally found this solution, since VLC was the only problematic app with Yosemite that I use.

Hi,

Thanks a lot for your analysis.

Now I didn't have Spotify installed until I tried installing it after seeing the errors in the log, so I doubt that was the problem. So I turned this setting to 'Do Nothing' and POOF! My hanging pauses stopped happening. If I turn it back to 'Pause iTunes /Spotify' and close iTunes, the problem doesn't occur.

Just to understand it right: Did the hang stopped because 1) you installed spotify, or 2) you closed iTunes? Maybe you can delete Spotify again to ensure that this is a sole problem with iTunes? Maybe its also only a problem with both of them...

Additional question: if you have actually music playing in iTunes: What is the behaviour? Is the music paused at the beginning or the end of the VLC hang?

No, installing Spotify didn't change anything.

Basically the hanging pauses stopped when I either:
Had the setting on ''Pause iTunes /Spotify' and had iTunes closed.
Had the setting on 'Do Nothing' and had iTunes open or closed.

So i think it's definitely VLC trying to pause iTunes 12.0.1 that is causing it.

And having the setting at ''Pause iTunes /Spotify' and iTunes 12.0.1 playing a song doesn't pause iTunes when i start playing a video.

I just tested it on Yosemite and for me it works totally fine, strangely. I have no concrete idea yet what is the exact issue. I assume you have a "normal iTunes" installation?

Yeah, normal iTunes

It's not the end of the world. I didn't even know that VLC would pause iTunes when I started playing videos, so leaving the setting off is fine for me.

I'm not as techie as you guys, but to me it simply looks like it's leaking memory, I work in a visual Enviroment and this reminds me of an issue we had couple years ago with a mkv standalone, but I do not have my Notebooks from back than any longer.

Sorry, but this bug pattern really looks like it has nothing to do with leaked memory. In this case you would not necessarily see hangs, but increased RAM consumption instead.
