Hi list, When I use ip cameras that uses rtsp/rtp protocol, if the camera sends the video stream in mjpeg or mpeg4 the system works well (I'm using live555 to capture rtsp streams). I receive all the image and send it to the filter decoder to decompress the image. When the camera sends H.264 over RTP, I receive one NAL unit in one RTP packet... packetizer mode = 1. I implement a packetizer like vlc packetizer, but after a few secons I receive this message: [h264 @ 0x8fa0a50]number of reference frames exceeds max (probably corrupt input), discarding one.
What I need to do to solve this? Can anyone help me? Sequence of frames (Hex): 1) 67 42 E0 14 DA 05 82 51 (nal unit type - 7 Sequence Parameter Set) 2) 68 CE 30 A4 80 (nal unit type - 8 Picture Parameter Set) 3) 06 E5 01 88 80 (nal unit type - 6 SEI Supplemental enhancement information) 4) 65 B8 .... (nal unit type - 5 Coded slice of an IDR picture) first I picture 5) 61 E2 .... (nal unit type - 1 Coded slice of a non-IDR picture) first P picture ...... What I understand from VLC code is that I need to find the first sincronization start code and join (1, 2, 3 and 4) to contruct one frame to decode, and frame 5, .... all P frames, and so one. Have anyone code to do this? Thanks, Nuno Cardoso.
