I want to have a J2ME application that displays a live streamed video,
text and some buttons. The textual infos and button actions have to be
synchronized with the live video stream. One use case is a tv shopping
channel. My current issue is to synchronize the video with the text and
button actions. First I tried to get the meta data I had embedded in
the RealMedia stream (using RMEvents tool and slta play lists). But
MetaDataController interface is not implemented on my N70. I found no
other Nokia platform that supports that interface. Therefor I tried to
use MediaTime (player.getMediaTime()). That seemed to be a good
solution until I found out that the MediaTime is not synchronized with
the current frames the user sees on his phone display. The MediaTime on
my phone is always 3-6 seconds ahead. This is at least my biggest
problem. I found no way to determine the amount of time that the
MediaTime is ahead.
Because of the MediaTime based problem I started to think about parsing
the rtsp stream to extract MetaData from the video stream on my own.
Has anyone tried that successful?
Has anyone similar experiences? Any alternative ideas or a solution?
cheers,
