Hello list, I'm working on an application that streams live generated content (audio and video) using the Darwin Streamnig Server. I decided to use ffmpeg for the encoding part and live555 for the streaming part. The basic architecture is as follows: In a first thread I generate the content, and in a second one I stream the content to the DSS. Data is passed between the threads using two buffers. I implemented two FramedSource subclasses for the streaming part, one for audio and one for video data. Both work as follows: They read raw data from their input buffer and encode it using ffmpeg (using MPEG4 and MP2 codecs) and write to their output buffers (fTo). My sources are then connected to an MPEG4VideoStreamFramer and an MPEG1or2AudioStreamFramer respectively. These are connected to a DarwinInjector (based on the code of testMPEG4VideoToDarwin). The problem I have now is that the streams are not synchronized when viewing them (using QuickTime or VLC). Based on debug printf's I found out that the audio source's doGetNextFrame() is called much more that the video source's. Therefore, the audio stream is played ahead and the video stream is lagging behind. I set correct presentation times for both streams, so I thought that live555 does 'the rest' synchronizing the streams, but it seems not to work. Therefore I'd like to ask you if I should implement a synchronization of the streams by myself, or if I'm doing something wrong...
I hope someone can help me and I'd like to thank you for any answers in advance! cheers, Severin _______________________________________________ live-devel mailing list live-devel@lists.live555.com http://lists.live555.com/mailman/listinfo/live-devel
