The VideoLAN Forums

Hi... I'm running VLC 2.1.4. From time to time, I get an Error and Warning window pop up even when there are no relevant (to me) issues with playback of the video I am watching. It is a bit annoying. Am wondering if there is a way to hide or disable this window from popping up. It is quite disruptive to the enjoyment of watching my playlist content in fullscreen when there is this silly window on top of my playing video that I have to get up and manually close. It reminds me of the old days when you had to get up to change the channel on the black and white tv console. Ok, sorry for the rant.

I searched the forums and did find a similar topic, but the solution does not seem to apply to VLC 2.1.4 on OS X.

No, there is no way. This dialog only pops up for _serious_ errors. Please post the errors and how to reproduce here...

I can't reproduce the errors. The same files now play without error/warning messages. ::SHRUG:: I was just hoping to prevent future popups, but as you say, there is no way. If I see them again, I will post here. Thanks for the help!

Thank you. That is the whole point - get the users notified so they can ask here in the end how to fix this error.

I have just encountered the same issue as BernieBone. I won't repeat his original post, but the only difference is that I am running VLC 2.2.1, on a MacBook Air OS X 10.11.2 ("El Capitan" - I guess they ran out of animals), with Safari 9.0.2. I would add that if the video is looping, the window has to be closed manually over and over again, which makes it essentially impossible to watch.

When I open a particular QuickTime (.mov) video, I get the following error message:

"Codec not supported
VLC could not decode the format "XiVs" (No description for this codec)"

- but the video seems to be playing just fine. (Perhaps there is some special feature I wouldn't be able to access?) VLC is still ahead of the game: QuickTime Player won't open that video at all; Flip Player opens it, but only displays a blank screen, even though it claims the video is playing and shows the time index.

I appreciate that "this dialog only pops up for serious errors", but if the video is playing fine for a regular user who basically just wants to watch it as is, and the issue is serious primarily for the developers, I still think there ought to be a way for non-advanced users to hide it, at least on a particular video. Unless it is sending out an automatic error report, it does you no good, and annoys me.

Tools, Interface, Main Interface, Qt, [check box] show unimportant error and warnings dialog
Problem solved!

Hey there, obviously this a pretty old post, nevertheless it is one of the top ranked google results when searching for an answer to the OP's question. I can't take credit for this answer as I found it elsewhere. Anyways, hopefully this helps anyone looking to Disable the Errors and Warnings Window on Mac OS X.

It worked for me using VLC Version 3.0.6 running on macOS 10.13.5 (High Sierra).

So simply, open the Terminal app and execute the following commands:


Now the Errors and Warnings Window should be gone. Good Luck
