Patch - Display slideshow at start-up

[Graham Jones (Physics)]

I wanted to use my MVP as a simple picture slideshow display, but it has to do it automatically without needing the user to do anything with the remote control.
I attach a patch that adds a command line option so that you can say

           --startup slideshow:file=<path to directory containing image files>.

All it does is set the file browser's working directory to the specified path, initialises the file browser and displays the first image in the directory.  It then simulates pressing the '1' key to start a slideshow.  Other features still seem to work, but I have not tested everything.

It works ok for me, but I did struggle to un-pick the source code, so there may be some 'housekeeping' bits that I have missed.

What is the process to get this feature added to the official source code?

Graham.

This is a good start.

You might want to talk about it in the users list to see if anyone has
any additional suggestions.  Also, you might find someone has already
implemented a similar feature (Martin's always good for that).

Yeah, I'm wondering why you need to fiddle w/loading image 0 then 1 as well.

It would be nice to be able to both 1) start the feature from the
command line and 2) enter/exit it from the menus.

(I can already see relaters flocking to buy MediaMVPs, setting them up
in their windows and showing off houses all night long.  At half the
price of a desk top!)

Thanks Stuart,
I didn't add a menu item for it because it is really just the file browser with a couple of simulated button presses, but if people think it would be better I can add it.  
I think a second parameter for the display interval would be good - 1 sec is a bit quick sometimes.

Cheers


Graham.

There is a new "signage" model of the pch that has software to do this
without a server.  Signage functionality might be something for the
plugin version in the future mxing video photos and audio.

A used MVP plus a used LCD computer monitor could make a nice
inexpensive "big screen" (19"+) photo frame, except the MVP has no VGA
output, and most computer monitors don't have a composite input. Though
a few do, like the 24" Gateway FPD2485W, it's 22" cousin, and a few others.

Now if you could just figure out how to hack in a touch screen and
connect that up to the MVP, then you'd really have something.

Looks like you can get boxes (comp -> vga) to do that for about $65:

I wish I had time to do this stuff.  I'm sure that an mvpmc box w/a
hacked serial port added could do this.  However, touch screens are just
as expensive as monitors:

but I found this on the mp3touchscreens.com site:

The reason I made this patch was to use it as a photo frame, but I am using an LCD TV rather than a monitor.  You are right, I could have bought another gadget to do something similar, but I had a MVP kicking around that I got a while ago and intended to turn into something 'useful'!

A touch screen is an interesting thought - I have made this for my disabled son to be able to use, but I am using a simple big push button  and a timer to power on the whole system for a set period (if I can persuade him to press it!).  A touch screen could be really neat - I'll have to have a look into it.....
