Stream Video to N770

[gavinlew]

Hi Everyone,

After some help with the following idea ;

I have a mythtv based linux server full of video/mp3/pictures ,

I have mp3 streaming working to my N770 with Canola and Twonkymedia as the UPnP server - this all works fine.

What I would like to get going now, is the video streaming (pictures is less important - it crashes canola currently) , from various reading it appears that Twonkymedia may not be able to encode on the fly?

I have tried Mediatomb , but the encoding again does not appear to be supported.

I have read that this is possible to achieve using Tversity on a windows box ; however all the media is served from a linux server.

Any ideas/pointers would be appreciated.

Cheers.

You may want to wait a bit for general availability of a fix for wlan related memory corruption problem (https://bugs.maemo.org/show_bug.cgi?id=2006) (resulting in poor device stability and random reboots on wifi use). Until you have a fixed wlan driver installed on your device, video streaming may suffer from all kind of weird problems.

You might be interested in my mediaserv (http://www.maemopeople.org/index.php/jaffa/) which seems to do a lot of what you want.

Cool, this looks perfect.

I've installed it and the relevant PERL modules on my back end server (Ubuntu Feisty)

It would appear that mplayer is going to have to be recompiled , everything works OK up until the point of launching the file to be streamed and this is noted in the console;

"Use of uninitialized value in pattern match (m//) at /home/mythtv/.mediaserv/770-encode.pl line 304.
Use of uninitialized value in pattern match (m//) at /home/mythtv/.mediaserv/770-encode.pl line 304.
mplayer doesn't support lavc encoder"

Ignore that, mencoder wasn't installed - apt-get fixed that.

Im now getting further, the Mediaplayer on the 770 opens now, but an error is generated - unable to perform operation then quits.

Seems that the call is passed to mencoder as per the console output ;

Hi,

I've not had any successful reports from IT OS 2006 users - I think the Media Player there is just crap for streaming. Using mplayer would probably be your best option, or upgrade to IT OS 2007HE.

Hope that helps,

Andrew

I have the hacker edition installed and I installed mediastreamer on my 770 and Home Media Server by simple center on my XP server.......works great. Go to tabelteer, enhance, mediastreamer and follow directions. Don't know if this works on regular 770....if now upgrade software to hacker edition.
