Master and slave stop playing after some time

[60-hz]

Since the beginning, I have this problem, both player stop and the master/slave are not sending position information anymore. Here is the video information:

I'm also running into this issue. For me, it seems omxplayer-sync simply stops.

I will run overnight video tests and at some point, one pi will stop playing. Usually the screen will be black when I see it. If I press any key on a keyboard, I will see the command line

pi@raspberrypi ~ $

Which means the player stopped and the screen went into screen saver from no input. I don't seen any error, so I don't know why it's stopping. Has anyone else come across this?

Turn off all screensaver, power saving etc. modes... you have to do this as pi user and also as root user.

[zhiwan]

I will try that but it seems that the screensaver/powersaving mode is occurring because omxplayer stopped, not because the screensaver is overriding the video, unless you think this is the case? It's not like when I hit a key on the keyboard that the screensaver then goes back to the video but instead I see the command line...

[magdesign]

Its definitely not a problem of omxplayer-sync... its running since days here...

[zhiwan]

Okay. So is the powersaving mode turning off omxplayer?

This is what I found:

Is this the steps you would recommend? I am also a bit confused by your comment about doing both as a pi user and root. Can you clarify?

[zhiwan]

I just turned off the powersaving mode and the video still stopped at one point. I will come to the video and see the command line. I'm not quite sure what is causing it...

[zhiwan]

At this point, I don't know if it's omxplayer-sync or my video, so I ended up writing a bashscript that checks that omxplayer-sync is running, and if not, it will reset it. It doesn't seem elegant but there doesn't seem to be anything else that has been suggested.

!/bin/sh

SERVICE='omxplayer-sync' while true; do if ps ax | grep -v grep | grep $SERVICE > /dev/null then echo "running" else /usr/bin/omxplayer-sync -mu -o both /home/pi/video.mp4 fi done
