Streaming mp4 videos from an Android device to gmediarender on a UPNP-enabled remote device

gmediarender is a resource efficient UPNP-compatible media renderer suitable for lower specification devices such as the Raspberry pi.

Skifta can be used as both media server and control point (i.e. the remote) but in my experience mp4 files can't be streamed from the Skifta server on the phone (HTC One V in this case) to gmediarender. This results is an error "media unable to perform play".

One solution is to use BubbleUPnP as the control point with the setting Mime-type check unchecked (this setting can be found under "UPNP tweaks"). Within BubbleUPnP on the Android device either Skifta or BubbleUPnP  can be used as the media server.  

Another app which works well with gmediarender is MediaHouse which plays back mp4s without any need to configure the app.   

The UPnP Play app seems to have the same issue with mp4's being streamed to gmediarender, it returns "unsupported format video/mp4"
