Re: Controlling OXMPlayer from Python Script

Hi Ken, Me again :) I was hoping to plug in a momentary switch to shutdown the pi. I've wired it all up and can see the button being detected in debug but the pi wasn't shutting down. Then I notice in the manual.pdf on page 38 it says "shutdown - not implemented" :( So that functionality is not ava...

I've hacked pipresents.py and added call(['sudo', 'shutdown', '-h', '-P', '-t 5','now']) at line 327.

It appears to have the desired effect.

Is this ok?

Trev
Yes it will be OK if you want to short circuit the 5 second delay, probably best to call self.tidy_up() first but not essential.

Add Motion to the 'Start Shows' field of the start show. Motion needs repeat to be singleshot, although interval might work.

Re: Push content to multiple Pi's

As Ghans suggests you could use the Liveshow in Pi Presents. There is a -l command line option to set the location of the directory containing the media and I see no reason why it should not be on a remote file server. I would be interested to know how you get on, I guess you will have to install so...

Do not open the back of a CRT TV unless you know precisely what you are doing. There are kilovolt voltages present which can kill you even when the tele is not switched on.

Re: Strings, lists and tuples muddle!

.cfg files is another possibility. If the the flag names are unique each flag can become a section of the file which is basically a windows .ini file.

Use configparser to read/write it to//from a dictionary.

.cfg files are easier to edit by hand than .json but .json files preserve order of entries.

Re: Controlling OXMPlayer from Python Script

Yes you should be able to do all of this. Pi Presents (see sig) does something similar if you want a ready built solution written in Python. Otherwise some people including myself in pp_omxdriver use pyomxplayer to interface with omxplayer and send run time commands from python. https://github.com/j...

Re: Analog Audio Clicking

This was fixed a few months ago. IIRC it was a firmware fix by Dom. I also think the firmware fix has now migrated (in Raspbian) from rpi-update to sudo apt-get upgrade.

there is still a click when the audio is started up but you should not get it between tracks.

It not the full screen not working but even after full screen it surrounded by black spaces.
It is because of the picture resolution i using is smaller than the monitor output resolution?
Yes very likely. Pi Presents does not scale the images.

Re: Increase GPIO cable length

Okay, so instead I do: GND -> long wire -> button -> long wire -> io 4 And the capacitor as a separate connection between the same two pins ? Of course I can use the resistors which are built into the pi. I will look up how to do that. Many thanks! Simplest possible solution. KenT, Is there any par...

Re: Increase GPIO cable length

Also a 10 nF capacitor between the pin and the ground at the Pi end of the wire will reduce any RF noise. Now here you're speaking of ground again. Please clarify which pins need to be connected. So the next things I will do are: - get a long thin wire for the button - get a 10kOhm pull-up resistor...
