Display turns off while playing livestreamer video (VLC 2.2.0, OS X 10.10.2)

[NilsE]

After upgrading to VLC 2.2.0, my display turns off after a period of inactivity even when a video is playing. This happens in both fullscreen and windowed mode. It did not happen with VLC 2.1.X. MacBook Pro with Retina Display, OS X 10.10.2.

[DeRaaf]

I second that. MacBook pro i5, OS X 10.10.2

edit:

Allthough not a "life threatening" bug (easily circumvented by not allowing the computer to turn off screen), it's really annoying. I reverted back to the previous version. 2.2.0 is just a little to buggy for me. Liked the styling changes though.

Works fine for me.

Would it be possible for you to upload a VLC log (from the messages window) to a service like pastebin.com and give a link here? Then we can look why its not working for you.

I tried to replicate with a local video file, and couldn't. Maybe the fact that I'm using livestreamer is important. I edited the thread title to reflect that.

They're short logs, so I'll just paste them here.

1. I saved this log after the video had been playing for about thirty seconds, before the screen had a chance to darken and turn off. This is the entire log:

2. This is a fresh instance of VLC. I waited until the screen darkened and turned off, then waited about ten more minutes (audio continued to play), then woke the screen by wiggling the cursor, then logged back into my user account, then saved this log:

Sorry, I forgot to mention: Please open the messages window _before_ starting playback, and keep it open. Otherwise you only get half of the logs.

I tried to replicate with a local video file, and couldn't. Maybe the fact that I'm using livestreamer is important. I edited the thread title to reflect that.

That I also second. I used a live streamer initiated from popcorn.

I reverted back to the previous version of VLC but think the logs should be the same as NilsE's.

[NilsE]

Command:

Code: Select all

livestreamer ustream.tv/NASAHDTV worst --player "/Applications/VLC.app/Contents/MacOS/VLC --file-logging --log-verbose=2 --logmode=html --logfile=vlc-log.html"

I waited for the screen to darken and turn off, and then immediately woke the screen before I was kicked back to the login screen. Then I quit VLC.

Result:
Log.

Don't worry about the TS discontinuity errors. Not all streams have them.

[dfuhrmann]

I can reproduce the problem when piping a file to VLC. So it seems to be related to the fact that VLC is started on command line, and/or input is the pipe. Could you open a bug report on https://trac.videolan.org/vlc/ ? Thanks.

[NilsE]

Created ticket #14046. Apologies in advance if I didn't use proper procedure to set ticket severity/milestone/etc.

[NilsE]

dfurhmann, I also notice that the play/pause button is always shown as a “play” arrow when I’m streaming. It works as a play/pause button, but the appearance of the control doesn’t change. Is this also related to #11585? Can you reproduce on a file piped in on the command line?

(How do you pipe in a file from the command line? I tried

Code: Select all

cat file.mpg | /Applications/VLC.app/Contents/MacOS/VLC -

, but interface threw “No suitable interface module”.)

[dfuhrmann]

Yes, its the same issue, and we know why already.

But its not easy to fix, because simple fixes whould change the behaviour for VLC usage from command line.

[NilsE]

OK, thanks.
