"Cannot play video"

Moppel · by **Moppel** » Mon Mar 15, 2010 2:29 pm

I wrote my own Videoplaying app (pretty simple) and I am having problems playing the video. It's not like I just hear the audio and no image is popping up. The only thing I get is the first picture of the video and then it gets stuck. The audio is playing properly though. After some seconds I get a message "Cannot play video. Sorry this video cannot be played".
I assume this has something to do with the encoding and/or the sdk version. I am using sdk 1.5 with a target emulator of 2.1. Data formats are mp4 and 3gp, nothing works. I've tried several mp4/3gp converter programs but without any result.

Does somebody have a clue what's going on?
