[SlimDevices: Plugins] squeezelite output to file for snapcast
I'm currently running a snapserver which plays the files that are stored in the /tmp/snapfifo file. So you can Code: cat someWaveFile.wav > /tmp/snapfifo and then it plays the song to all snapcast clients that are currently connect to this server. I tried: Code: squeezelite -o - > /tmp/snapfifo but I only got some noise while playing a song through LMS Has someone already got this working? gekoch's Profile: http://forums.slimdevices.com/member.php?userid=71033 View this thread: http://forums.slimdevices.com/showthread.php?t=113394 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins

IIRC what is saved is a PCM stream. You need add a WAV header to tell any player the format of the PCM stream such as sample rate , sample size, endian, signed/unsiged etc. bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=113394 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins

If OP needs a WAV header the "-a" and "-r" will not provide it. Also I think when output is to a file "-o" the "-a" option is not required as it is ALSA specific. bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=113394 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins

Re: [SlimDevices: Plugins] squeezelite output to file for snapcast
now after it has worked for almost an year I have a problem with the filesize of the /tmp/snapfifo. It gets insanely big as big as the hardrive allows it (several GB) How can I stop it from growing that big in a matter of seconds after I launched: Code: /usr/bin/squeezelite -s 192.168.1.47 -a 16 -o - > /tmp/snapfifo gekoch's Profile: http://forums.slimdevices.com/member.php?userid=71033 View this thread: http://forums.slimdevices.com/showthread.php?t=113394 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins

Re: [SlimDevices: Plugins] squeezelite output to file for snapcast
on LMS there is a radio station playing. But after 15s the snapfifo file is around 10GB and the system is not reacting anymore... Does squeezlite fill the snapfifo File with junk? gekoch's Profile: http://forums.slimdevices.com/member.php?userid=71033 View this thread: http://forums.slimdevices.com/showthread.php?t=113394 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins

Squeezelite cannot just generate junk - it has to play audio all the time. It outputs the audio from its source or silence (which is a stream of PCM bytes of data) if there is nothing from the source. Use "tee" to see what is being put into fifo. Use squezelite logging to see exactly what is going on. bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=113394 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins
Re: [SlimDevices: Plugins] squeezelite output to file for snapcast
hmm I was able to solve it... as soon as snapserver started and no /tmp/snapfifo was available snapserver did create a file with "snapserver" as owner and group when I then tried to launch squeezlite with: Code: /usr/bin/squeezelite -s 192.168.1.47 -n evita -a 16 -o - > /tmp/snapfifo I would get an Persmission denied. When I stop snpaserver and let it run from the terminal with root everything is working as excepted. So what is the best way to start squeezelite also under the "snapserver" owner so it has permission to write to the /tmp/snapfifo file? Or should I both run as root? gekoch's Profile: http://forums.slimdevices.com/member.php?userid=71033 View this thread: http://forums.slimdevices.com/showthread.php?t=113394 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins

In principle, running application as root is not a good idea as it means things are not being done properly and could end up very badly. I think you need to read up about running services which I don't know much but you probably need to create a script where the sequence of commands is done but with each step tested. A simpler approach might be to check - if it worked before and not now - what has changed ? bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=113394 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins
