I am thinking around a problem and wondered if anyone here knows anything about this.

Any idea how to combine all video, and all audio for a profile into single files using ffmpeg?

I am thinking "video sprites" as a way around restrictions in iOS.

Thanks
:)

Did a related project recently where uploaded audio gets overlaid with "this is some site" type tagging using 'sox'.

It took the uploaded "this is some-site.com" audio snipit, added some seconds of silence to it, then grafted that together until it was long enough to exceed the length of any uploaded song.

Sent invite to the channel if you want to take a look for anything useful in there. sent to s....@u....e.com

The bit I think you're interested in is around line 284 of include.php where the track is manipulated, then joined together.

Then for your concept, grab all the mp3 files you're interested in and

Thanks Michael, that was very useful.

For now I have made an item module with a simple tool for the admin to enter a profile id, all the audio files are concatenated into a single file and created as a profile item for the module.

Still have to make that work on the front end, but I'm pleased with my profgress for this weekend.

Thanks :) !!!
