Hi,
I started to look at at Media Mover to research the possibilities to transcode video uploaded to Drupal into Mobile device capable formats. I am working on the Wurfl module who is able to provide me information on encoding formats supported by mobile devices.
I was wondering if someone with Media Mover experience would be able to share his thoughts on how a Media Mover helper module would have to be implemented to provide this.
The flow I see is:
- Harvest video file from uploaded node
- Process video file by transcoding in 5 fixed transcoding configuration
- When viewing, device capabilities are detected
- right movie is delivered to the device
Any thoughts on impelmentations (what can I reuse, or what should I do).
Thanks for getting me on speed :)

flvmediaplayer has a noflash parameter which you can use to pass a different file to the display when the display device does not support flash (eg: iphone). I've used this approach which can work well- theme('flvmediaplayer_build_embed', $node, $profile, $params) is what you want

Thanks!
I'll give it a try.

Tom - i've done part 1 and 2 of what you need. i.e. the user uploads the file and it is converted into 5 specific putput types. Trying to figure out the rest myself.
You can contact me directly at gargsuchi at gmail dot com and we can collaborate on something like this.

Hey there. Assuming that what you want to do is sendvideo from your drupal site to a user's phone, at vozmob.net we use this method:
1. get the user number and phone provider
2. to send the user a video, send an email to usernumber@companymmstoemailgateway.com, for example: 9876543210@mms.att.net, with the video attached
3. the phone company email to mms gateway will transcode the attached video to the appropriate format and send it to the user as an mms ;)
That way, you only need a database with the phone company email to mms gateway addys, rather than a DB with all handsets and the filetypes they support ;)
If the company has no gateway, then with this method you would need to make your own email to mms gateway. We will be working on this, there's a FOSS gateway called mbuni and we want to integrate it with Drupal.
check our work out at http://vozmob.net, http://code.vozmob.net, http://dev.vozmob.net, and irc://freenode/vozmob
thanks

Other method, independent from mms limitations is explained here: Posting video from mobile phones into Drupal

Hey szczym, I think they want to go the other direction (video from drupal --> mobile phones). But thanks for the tutorial :)

Well, media mover should handle all the transcoding for you- you just need to write a theming function that can detect the device and deliver the appropriate file. Do you have a list of devices you need to support?

re: MMS gateways, I am not aware of any carrier MMS gateways that will transcode videos for you, although it's conceivable. What I do know is that you can send media files (in supported formats) via e-mail to these gateways and they will forward it on to the phone as an MMS message. Multiple image files will appear on the phone as a slideshow. Audio files and text work too. For at least some carriers and/or phones, videos don't play directly on the phone. Your phone just gets a message that you received a video and that you have to visit the carrier's website on a computer to play it.
