paste here what is in mine

# serial-media-srv
a media server that plays movies or images controlled by serial cmds.

This server could be used in various devices to playback movies or images based on the received serial commands.

# running

There's a start script provided start.sh and a service definition for systemd as well (serial-media.service).
To install the service copy serial-media.service to /etc/systemd/system adjust installation path and start/enable the service by systemctl start/enable serial-media

# config

The service reads a config file (ini file) from the current directory by default (serial-media-srv.ini). It consists of sections see example. There a builtin defaults for showing images and also for playing movies that rely on omxplayer / fim.

# commands

Ther service reads commands from the serial port (or other input) just as one line. Commands are always uppercase and can have arguments.

## play command

PLAY <media>

plays / shows a media file (image / movie)

## stop command

STOP

stop any running media, go back to a default (if defined)

## playoneof command

PLAYONEOF <media1> <media2> <media3>

plays one of the media files, chooses randomly

# movie playback
if a movie is playing the server remembers its name, so if the same movie is requested twice, the movie just plays on (no rewind or interruption)

# install on raspbian stretch / dietpi

Beginning with version 1.0.4 the serial media server is no longer using yamuplay or omxplayer python extension (didn't work).
There is also an image available to make the setup even easier, see here https://go-dmd.de/produkt/serial-media-server-image/

Base image is raspian lite stretch or dietpi. Then run / install the following commands ...

`
apt-get update
apt-get install omxplayer
apt-get install fbset
apt-get install fbi
apt-get install fim
apt-get install python3-setuptools
// apt-get install python3-dbus
apt-get install python3-pip

// python3 -m pip install decorator
// python3 -m pip install evento
python3 -m pip install pyserial

// apt-get install git
// git clone https://github.com/schlizbaeda/yamuplay.git
`
Take care to have enough GPU memory configured so that omxplayer can work

# usb stick support
start script has usb stick support and dectects a mounted usb stick using media from there (requires usbmount installed)

# config file
the server read an ini like config file either from sd card (/data) or usb stick. see example dir how it could look. There are defaults being used when no config file is avail. The example below has all the defaults set.

`ini
[general]
# just for testing: read comamnds from a test file
# readFrom=input.txt
# uncomment to activate a simple text based socket interface, that accepts the same commands as over serial line
socketport=19999
# change the http port for web ui
httpport=31009
# the serial device
device=/dev/ttyS0
# the baud rate
baud=57600
# timeout in sec for reading the serial port
timeout=10

[player]
# command to use when playing videos
exec=omxplayer -b --no-osd

[viewer]
# command to use when showing images
exec=fim -a -q
`

# image

There is also an image available based on raspbian stretch lite the could be written on a 16GB sd card using some imager tool
like Win32 Disk Imager or Etcher. The image is even more customized as all startup messages on the screen are removed and a nice
start animation is shown instead. You can get the image here: https://go-dmd.de/produkt/serial-media-server-image/

# start

python3 img-mov-srv.py [ basedir ] [ device ]

I must be missing something, because I have a tiltaudio! image again, test in web UI to send a sound but no video is triggering

man, thank you so much for your help. I wouldn't have made it this far without your help.

hi man, after several attempts it worked as it should and I'm very happy, but it doesn't work the first time I turn on the machine, after I have to access the web ui, go to the settings tab and just press the restart button, from there it works usually.
I would like to know if there is any way to change this, so that every time I turn on the machine it works, without having to restart every time I want to use it

I noticed on the thread about rebuilding sound for data east jurassic park using a pi that steve45 said that there were problems with the latest firmware and the pi 4. Does that still hold? If I want to build this sound and video solution for cftbl should I use a pi 3 b+ or a pi 4?
Thanks
John

Hi

I am trying to setup the holo display on the the same pi as the tilt!audio. I am having a problem getting the omxplayer to run. Every time I try to manually execute the omxplayer I get the following error:

root@tiltaudio3:/boot/smsdata/data# omxplayer -b -no -osd /boot/smsdata/data/attract.mp4
/home/pi/bin/omxplayer.bin: error while loading shared libraries: libavutil.so.55: cannot open shared object file: No such file or directory

I have tried to find the libavutil.so.55 every place I can think of. I did find a libavutil.so.56 but of course that won't work. I am running titl!audio 3.10 board with rev 1.41 of the software. ANy ideas on where/how I can get the missing library?

thanks
John

Thanks ZigZag

ffmpeg is already installed - no joy

Thanks

John

Thanks for the suggestion. After adding libavutil-dev still getting

/home/pi/bin/omxplayer.bin: error while loading shared libraries: libavutil.so.55: cannot open shared object file: No such file or directory

thanks

John

Okay still not getting any display on my hdmi panel. I have the following error in the logfile:

2022-12-07 17:08:50.368 INFO RasPiSnd [serialSetup] [serial.c:64] Succesfully opened UART device '/dev/ttyS0'.

2022-12-07 17:08:50.369 INFO RasPiSnd [initGpio] [pincom.c:406] setting up GPIO for WPC

I suspect this is the culprit, but I haven't found any info on it yet. I am running on a PI 4 on a rev 3.10 board with rev 1.40.

Any thoughts on how to debug this?

Thanks
John

Yes, I have done all the things you specified and checked them multiple times. The serial-media service is running (output below)

I am currently stumped. Are there other logs I can check for errors?

Thanks

I have tried netstat -ano | grep 19999 and the result is nothing - I think this means that the serial-media.service is not listening on port 19999
