Hi Ross, Thanks for live555 library, our RTSP server works well. Thanks. And one question for sync video/audio stream. Background: Our system will prepare audio/video frames to memory, always capture frames from driver. For video, it is H264, FPS is 30 and driver output one I frame per second. For audio, it is AAC, 16KHz. Behavior: When player ask RTSP streaming from our server. For video stream, we go to memory and find latest I frame to send. For audio stream, we go to memory and find latest frame to send. On worst case, first timestamp of video frame <= first timestamp of audio frame + 1(second). Question: We want to sync video/audio streams when player ask a stream. Video/audio streams are belonged to same ServerMediaSession. Is it possible to pass the first timestamp of video frame to audio stream? Is there a way to sync data between FramedSource? Please advise. Thank you very much. Have a nice day.
