Hi~ My application gets the mpeg4 video stream from a AXIS camera and displays it on a x-window. Everything works perfectly. However, I have a problem with recording the video to the file. The problem is that ffdec_mpeg4 gets or sets (not sure who has set) wrong frame rate. The sdp from rtspsrc said, the frame rate is 30/1 (sdp attribute belonged to a media "a=framerate: 30.0"). However, the source pad of ffdec_mpeg4 has frame rate of 100/1. So, When I record the stream and plays it, it runs approximately three times faster than what it is suppoesed to do. I think either one of upstream elements, rtspsrc and rtpmp4vdepay, or ffdec_mpeg4 is doing something wrong. Do you guys think it it a bug? What's you think about it? Thanks, Justin
