There is a typo in this line:

Code:

# /opt/ffmepg/ffmpeg
-sh: /opt/ffmepg/ffmpeg: No such file or directory

It should say ffmpeg, not ffmepg. If you have used ffmepg in stream.converter, this is the reason for the error message.

Sorry! Typo at the command line! The stream.converter command line is correct.

Thanks for confirming. Please try running these two commands:

Code:

/opt/ffmpeg/ffmpeg -ar 48000 -f s16le -i /dev/null -f s16le -y -
echo $?

If the first command completes without errors and the second command returns 0, ffmpeg should be working OK.

How do I restart MininStreamer? Do I have to reboot the Qnap to do it?

[simoncn]

Thanks for this. Everything looks fine with your ffmpeg installation. You can restart MinimStreamer by stopping MinimServer in Package Center and then starting MinimServer again.

If this doesn't help, remove your stream.options setting and stop and restart MinimServer again.

There doesn't appear to be a way to actually "stop" it. I'd rather not do a kill -9 via command line.

[simoncn]

In App Center, click the down arrow next to the word Open underneath the MinimServer icon, then select Stop. After this, click Start underneath the MinimServer icon.

Are you 100% sure you have entered /opt/ffmpeg/ffmpeg (exactly that) in stream.converter?

[tony22]

Duh.

So I restarted it with the stream.converter just set to ffmpeg and it started fine. I changed the stream.converter to /opt/ffmpeg/ffmpeg, stopped it this way and then restarted it and now it seems to be working! The last time, I rebooted the Qnap, and then had that problem.
