... Never mentioned syncing, I just need them playing. They will do that right? I just ordered two Raspberries today. Model B 512mb. I should get them looping a video on vga screens.

... is able to get this to work, it would be great. What I'm trying to do is get Colby's innovation to start, via cron, and be able to stop the loop with something in a script, so that i can play another (different) video, also with hello_video.

Thanks everyone for the really helpful information. I too would be really interested in getting video and audio to seamlessly loop using hello_video I've spent a few days figuring out the right conversion format for my video files so that they are raw H264 and thus playable in hello_video. ...

Hey rulevu,

I haven't tried it at the moment, but I'd assume you could use the audio half of the video as an MP3, and play it back with MPG123, using the --loop -1 option.

I'm sure it's a simple matter to set up a script to do so. I'll make one myself, and get back to you on that.

Cheers,
Skeeball

With some edits of the scripts I was able to get a video loop running on bootup however on the 2nd pass I can see the desktop but the first time through the video runs full screen. What can I do to always have the video full screen?

... version of Debian for the Pi was Squeeze, "debian6-13-04-2012" is the name of the file (pretty sure that's the one). That one still works with the looping thank goodness, because I just installed two video pieces at a show which are running on two of my pis. Recently I spent quite a while trying ...

Hey Ken, I'm actually trying to loop video on boot too, would you mind giving me a rundown on what you did? I'm not sure entirely what you did, or how to put my own videos into hello_video. Could you tell me exactly what you did? Thanks, ...

Hey Ken,

Thanks Dom! Outstanding. I love that the solution was so simple. I am now getting a video loop that doesn't have even the slightest hesitation. Next I need to add looping sound (synchronized, of course), and I need a way to have the Pi be plug-and-play for my video loops. ...

@colbyparsons

Change:

Code: Select all

         if(!data_len)
            break;

to:

Code: Select all

         if(!data_len)
            fseek(in, 0, SEEK_SET);

and your video will play in an endless loop.
