This has been failing to build on the nightlies for a few days. It looks like this version may have been removed.

If there is a better place to report this or not report failures like this, please let me know.

Here is my build command

This would be great for libreelec to put it on par with most smart tvs which tend to include some kind of ariplay or casting. Thanks and good luck with the effort.

I have resolved this issue. There were two issues preventing this from working. One was the container was configured to run as a non-root user in start.sh. The second is specifying the correct device name as the default would not work. There apparently is no hardware mixer or I could not find the correct configuration.

#!/bin/sh

#start.sh

set -e

rm -rf /var/run/dbus.pid

#mkdir -p /var/run/dbus

dbus-uuidgen --ensure

dbus-daemon --system

avahi-daemon --daemonize --no-chroot

#su-exec shairport-sync shairport-sync $@ --Does not work

#su-exec root shairport-sync $@ -- Works

shairport-sync $@ # Works

shairport-sync.conf:

...

// Back End Settings

// These are parameters for the "alsa" audio back end.

// For this section to be operative, Shairport Sync must be built with the following configuration flag:

// --with-alsa

alsa =

{

output_device = "hdmi:CARD=HDMI,DEV=0"; // the name of the alsa output device. Use "shairport-sync -h" to discover the names of ALSA hardware devices. Use "alsamix>

// mixer_control_name = "PCM"; // the name of the mixer to use to adjust output volume. If not specified, volume in adjusted in software.

// mixer_device = "HDMI,DEV=0"; //

...

Thanks to all who replied.

Now I know that speaker-test works from Docker on Libreelec, I was hoping to get some help getting the shairport-sync-docker container running. I can run it just fine on Debian so I know it works.

I have been working with the author trying get his container to run on Libreelec but have not had any success and just get these errors in the container log. Many combinations have been tried. I think it comes down to linux security and device access.

If anybody has any suggestions things to try differently in the Dockerfile or the Entrypoint start.sh, it would be greatly appreciated.

Quote from elonesna

Go back to studying the documentation about docker, the --privileged parameter allows access to the hardware and therefore the audio output

Thank you for the reply.

The rest of this post basically answers my original question since today I was able to have success with speaker-test in a container and could hear it from the receiver.

I had found --privileged and used it in prior attempts. It does permit the listing of /proc/asound, but I could not get beyond that.

ls -al /proc/asound

I made a docker container to run speaker-test and did get sound output. Dockerfile:

Thanks to all.

Is it possible for Docker containers to output audio to alsa on Libreelec? I have done a lot of searching and have not seen this question answered directly, but indirectly I see indications that yes it can and no it can't.

If it can is there some kind of reference container that shows the proof of concept?

Is there a work around using pulse audio or some other means?

Thanks all.

Solved

The TV was in Stretch view mode. Chrome works perfectly now.

-----------------

Thanks for getting Chrome up and running in LE 10.

I am having one issue with it in that it overscans so that the top right minimize/restore/full screen buttons are not visible and the left side back arrow is not visible. The mouse can still get to the buttons, but it takes some guessing and practice.

I tried various settings for the addon and tried underscanning Kodi, but nothing worked. I did not see any advanced setting in Chrome that might help.

Running on generic x64 with an Nvidia 1030 card. Would posting logs help or do you have any another suggestions for a fix? Thanks.

Quote from mglae

Likely DOS line endings. Try dos2unix /storage/.kodi/userdata/keymaps/AVMD0.py

Edit:

Thanks mglae, that worked. I'll stick with nano and notepad++ now.

I have it working as it should now. I changed the xml file from remote.xml instead of keyboard.xml. I am not sure it made the difference, but is correct in this case.

In addition to the tv View Mode that was toggling, I was getting some kind of kodi context windows up most of the time, especially on successive key process.

I changed the key from f12 to alt-f12 and it made no difference, but I am sticking with that.

I then changed the MCE remote key from Visualizations to Aspect and it fixed the problem. The visualizations key must be sending some kind of multiple codes that flirc didn't process with the key map.

Thanks again to all who chimed in here and to all the libreelec and kodi contributors!

Thanks for your reply lrusak. I tried that and the f12 key press is still recognized, but nothing happens which is somewhat of an improvement. Does it matter that python script does not work at the command line unless the interpreter is specified?

Using Libreelec 10 beta 2, I am trying to map a keyboard f12 key to this System.Exec() call in order to toggle the AV mode over a tcp socket from my keyboard or remote.

It seems to do something because if I press f12 twice it resets Kodi, so something is wrong and I could use some help or suggestions for a better way to accomplish the same thing. It does not toggle the AV mode like the command does in an ssh window.

I tried to use log file uploader, but it crashed. I send a one of the log files and try again with the log file uploader if needed.

Per the log, I can see that the keymap is applied when f12 is pressed and it tries to run python3 /storage/.kodi/userdata/keymaps/AVMD0.py. The command python3 /storage/.kodi/userdata/keymaps/AVMD0.py or /usr/bin/python3 /storage/.kodi/userdata/keymaps/AVMD0.py runs perfectly from an ssh command line.

keymap.xml:

tcpsocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

tcpsocket.connect( ('192.168.1.206', 10002) )

tcpsocket.sendall(b'\rAVMD0 \r')

data = tcpsocket.recv(1024)

tcpsocket.close()

#print('Received', repr(data))

exit

Two F12 key presses from the log:
