Streaming internet radio when browsing for games and on screensaver?
-
One last thought guys...is there anyway to make the radio fade out rather than cut out once a game is selected and fade back in when you exit a game?
No big issue but just a thought?
Thanks again
:)

@pipesfranco I actually tried adding a cross-fade effect when stopping/resuming vlc, but it does not support that. Various searches on the interwebs show that it's not implemented in currently (see for instance this ticket).
I'll see if we can find an alternative to VLC that supports both streaming from internet radio sources and fade out/in for audio.

Raspberry Pi 3B
2.4A power supply
Raspbian Stretch
RetroPie 4.3.1I haven't been able to get this working properly. I suspect there is a problem with my particular setup. I have RetroPie installed on top of Raspbian Stretch, which I know has issues.
Step 1 and 4 work fine for me. I was able to install everything, add my station (AI Radio), and get it to start playing automatically when emulationstation starts. However, step 2 and 3 are where everything falls apart.
The step 2
runcommand-onstart.sh
breaks my runcommand. The music keeps playing and my chosen emulator fails to launch. I tried copy-pasting. I tried typing by hand. I even looked at the other thread and used chmod to allow execution privileges for all. It didn't work. The files were newly created and no other commands were added.As for Step 3, my .bashrc doesn't have a
retropie_welcome
or#RETROPIE PROFILE END
Again, it is clear some people have gotten this working, so it is probably down to my particular setup. I'm just not sure what I did wrong.

@nowarrivinghere Can you paste here the contents of the
/opt/retropie/configs/all/runcommand-onstart.sh
file ? It seems this is the stuff that breaks for you. -
@mitu
Sure. Here you goecho -n pause | nc -U /tmp/radio.sock >/dev/null 2>&1
-
@nowarrivinghere You might be missing the
nc
utility. Does the command works if you run it in a terminal ? Just typenc
and see if you get any error. -
pi@raspberrypi:~ $ nc usage: nc [-46CDdFhklNnrStUuvZz] [-I length] [-i interval] [-O length] [-P proxy_username] [-p source_port] [-q seconds] [-s source] [-T toskeyword] [-V rtable] [-w timeout] [-X proxy_protocol] [-x proxy_address[:port]] [destination] [port]
-
@nowarrivinghere So
netcat
is installed. What happens if you run the command from the onstart file manually, after ES is started and the music plays ? It should pause the music.echo -n pause | nc -U /tmp/radio.sock >/dev/null 2>&1
Can you run the command from a SSH session and see what's the outcome ? If it works (i.e. music is paused), try starting a game and (after you get thrown back to ES ) then paste the contents of the
/var/shm/runcommand.log
file, we might have some clues there. -
@jonnykesh said in Streaming internet radio when browsing for games and on screensaver?:
I wish I could remember who wrote it so I could give them credit.
Not written completly just modified a bit... but I introduced here.... with correspondending source ;)

Okay, I just used SSH to try the pause command while the music was playing. I've waited about 90 seconds. Music is still playing and the SSH window is unresponsive.
-
@nowarrivinghere Sorry, forgot about removing the redirection. Execute this:
ls -l /tmp/radio.sock echo -n pause | nc -U /tmp/radio.sock
I suspect it might be a permission problem.
-
Still fails to pause and leaves the window stuck.
pi@raspberrypi:~ $ ls -l /tmp/radio.sock srwxr-xr-x 1 pi pi 0 Oct 4 16:42 /tmp/radio.sock pi@raspberrypi:~ $ echo -n pause | nc -U /tmp/radio.sock

@nowarrivinghere I have no idea why it does that - maybe Stretch has a different version of VLC that's not the same as the one I tested and the old interface doesn't work anymore ?
Just to check if there is a problem with newer versions, kill the VLC that is started via the autostart with
killall vlc
, then start the playback directly from thessh
session, by runningvlc -I oldrc --rc-unix /tmp/radio.sock -Zq --no-video /home/pi/radio/list.txt
You should get the radion playing this way with logging from VLC on the terminal.
Now, from a 2nd SSH session, run theecho
command that's giving you trouble and see if it pauses the stream or any error appears in the 1st terminal, where VLC is running.Other than that, maybe the output of
/dev/shm/runcommand.log
from starting a game might be of use. -
Okay, this is interesting, I opened SSH Window 1, killed vlc, and reopened it via the command you gave. Then, in SSH Window 2, I ran the pause command. It appeared to sit there with the music still playing just as before. However, I then did a CTRL+C in Window 2 and it paused. Then I used the pause command in Window 2 again. Once again, it just sat there silently. Then I did CTRL+C and sure enough it started playing music again. Also, here is the output that appeared in Window 1.
status change: ( new input: http://listen.ai-radio.org:8000/128.ogg?cc=US&now=1507110308.444& ) status change: ( play state: 3 ) pause: returned 0 (no error) status change: ( pause state: 3 ): Pause status change: ( pause state: 4 ) pause: returned 0 (no error) status change: ( play state: 2 ): Play status change: ( play state: 3 ) pause: returned 0 (no error) status change: ( pause state: 3 ): Pause status change: ( play state: 3 ) pause: returned 0 (no error)
EDIT: I decided to just place the script that jonnykesh brought us inside my
runcommand-onstart.sh
andruncommand-onend.sh
with thempg123
replaced withvlc
. That seems to work and perform the function of thepause
command on the cases I have tried so far. Its probably not as efficient as the actual vlc controls, but I haven't noticed a delay from a human perspective. It is more efficient than just using thekill all
command and then that command we added inautostart.sh
and restarting vlc every time though, which was my backup plan and did introduce a delay. Would be nice to have access to the other vlc controls, but I can't think of anything else to try right now. -
@nowarrivinghere This means the
netcat
commands you run in the 2nd window reads the pause command but it doesn't send it right away and awaits further input.
I'll do some testing with the version in Stretch to see if it behaves differently than the one in the Jessie release, but glad you got it working with the alternate start/stop command. -
Ok, found out the difference - tested on a Stretch system. The
netcat
command doesn't return and still waits for input from the tty. To force it to close the input, using-N
seems to do the trick.
@NowArrivingHere you can try changing the on-start/on-end commands toecho -n pause | nc -UN /tmp/radio.sock
Unfortunately the
-N
option doesn't exist in the Jessie version ofnetcat-openbsd
, I'll see if we can ditchnetcat
completely and use something else. -
OK, I've found a way to ditch
netcat
- by replacing it withsocat
. I have updated the instructions steps with the new commands (steps 2 and 3, plus the pre-requisites).
This should work on both Jessie and Stretch - and possibly other systems. -
@mitu
Thanks mate. It is pausing and playing properly now. -

-
@mtib Emulationstation has an audio volume knob which allows you to change the volume - doesn't it work for the background music ?
Alternatively you can add the--gain
parameter to thempg123
to set the volume (0-100):# to set the volume to 40% mpg123 --gain 40 [..other parameters following..]
