Looks like a stream connection error in omxplayer. You can try executing the commands (youtube-dl, omxplayer, omxdbus) manually and see if that happens again.

It shouldn't be an issue related to gotubecast :)

I have go version 1.9.2 installed
youtube-dl works fine. With -g parameter returns https URL of video. Without -g parameter always download mp4 file.
omxplayer also works fine, when I start it from command line........
omxdbus not tested.
But when I place more videos in play list, first video started OK.
Jump to nex video will start next video (vithout any omxdbus command) and program is crashed.
omxplayer continue with playing current video

Now I tested again.
Downloaded new raspi image 2017-11-29-raspbian-stretch.img
first boot: Set SSH access and pi user password
apt-get update
apt-get install omxplayer - was installed in raspbian-stretch.img image
apt-get install youtube-dl - install OK
cd /tmp
wget https://redirector.gvt1.com/edgedl/go/go1.8.5.linux-armv6l.tar.gz
tar -C /usr/local -xzf go1.8.5.linux-armv6l.tar.gz
export PATH=$PATH:/usr/local/go/bin

command go version return go version go1.8.5 linux/arm --OK

cd ~
go get github.com/CBiX/gotubecast
export PATH=$PATH:~/go/bin
cd ./home/pi/go/src/github.com/CBiX/gotubecast/examples
./raspi.sh

Also tested with fresh build gotubecast with go build main.go

Result same, only difference is

Now I tried modify raspi.sh

   video_id)
        YTURL="`youtube-dl -g $YTDL_OPTS https://youtube.com?v=$arg`"
        killall omxplayer.bin
        omxplayer $OMX_OPTS "$YTURL" &
        ;;
    play | pause)
        echo "PLAY|PAUSE pressed block begin"
       //omxdbus org.mpris.MediaPlayer2.Player.PlayPause  // **LINE IS COMMENTED**
        echo "PLAY|PAUSE pressed block end"
        ;;
    stop)
        omxdbus org.mpris.MediaPlayer2.Player.Stop
        ;;

Result for pause command while playing:
V:PortSettingsChanged: 1280x720@25.00 interlace:0 deinterlace:0 anaglyph:0 par:1.00 display:0 layer:0 alpha:255 aspectMode:0
PLAY|PAUSE pressed block begin
PLAY|PAUSE pressed block end
./raspi.sh: line 19: read: read error: 0: Resource temporarily unavailable

It seems like raspi.sh cant read output from gotubecast
No procces for omxplayer or omxplayer controll.
Also no work for youtube-dl.............

After pressed pause button program stopped.

Added line echo $line >> raspi.log to raspi.sh do while

log is:

I had the same problem, but managed to fix it after some amount of googling. The fix is simple, in raspi.sh:

omxplayer $OMX_OPTS "$YTURL" < /dev/null &

omxplayer is taking input from stdin which causes the line read to fail I think.

[cbix]

Hey guys, sorry for the late comment on this. Unfortunately I don't have any RasPi environment now to test omxplayer. Did you manage to fix it with the change from @koochyrat?

[hsmptg]

Hi
Just to confirm that the solution proposed by koochyrat also solve me the same problem!
