We have a J2ME MMAPI application which plays streaming (RTSP, H.264) 3gp video. Intermittently, we only get audio playback, but no video.
The video is streaming from our own Darwin Streaming Server, and the phone we are testing with is a 6220C. The problem is intermittent -- most of the time, video will play with no problems. However, occasionally, a video which was previously playing fine will play with audio only.
What is likely to be the cause of *intermittent* streaming video playback problems?
