Problems with rc commands from another app.

[Dinosaur1946]

Hi All

The Target:
Rpi Zero W has push buttons to select Video's in a Museum.
Buttons can be pressed in the middle of another video to change to another.

The app is written in FreeBasic and uses the Pipe command:
ie:

Code: Select all

PipeCmnd = "vlc -I rc Video1.mov fullscreen" Open Pipe PipeCmnd for Output as #1 StartTime = Timer do Here I wait for a button press and decide what action to take. loop

Now this is where the issues come in.If I close the Pipe and re-open it with different
video information, the vlc screen closes and reverts to the cli.
It then has to re-open the vlc screen to play the next selection.
The idea is to stop the playing video and tell vlc to play another.
Reading and Googling until I was googly eyed, I cannot resolve how to use the rc commands to achieve this.
Yes, I can see all the different commands and dream about using , stop , play etc.
Whatever I have tried results in vlc not recognising the command.

In FreeBasic, once the Pipe is opened, you then send the next commands by using a print statement.
ie: Print #1, "stop"
Which works, But
Print #1,"play Video2.mov"
or
Print #1,"play 'Video2.mov'"
don't, I get the following screen print.

Code: Select all

dinosaur@debian:~/projects/SimpleVLC$ ./Test VLC media player 3.0.21 Vetinari (revision 3.0.21-0-gdd8bfdbabe8) VLC media player 3.0.21 Vetinari Command Line Interface initialized.

Any suggestions greatly appreciated.

VLC exits when its standard input ends just like every other programme reading from the standard input.

Don't do that if you don't want it to exit, obviously.

Hi All

Appreciate that.
Is there anyway to allow me to Interrupt the video, and nominate a new one ? (without vlc exiting)
