Thanks for your fast answer. But I still have a few questions.
I read at "Video in Nokia Phones 1.0":
Real Player ..... This player is gradually replacing Nokia Video Player in Nokia 3650 ...
1.- Does this mean that Real will play MMS attachments in the future?
2.- Must I only embed "H.263 + AMR" video in MMS messages?
3.- Is there any other "codec" I can use to generate videos for direct playing in MMS messages (Mpeg4, ...)
4.- I still would like to have a Smil example of the RSTP:// protocol.
1. ROP can play MMS attachments signed to it already now, but not in the MMS viewer.
2. As H.263 and AMR are 3GPP standards, I suggest to use those.
4. ...to embed an rstp link to the MMS message???
