Hi, One of the customers uses eveostream rtsp streaming server. We are implementing a client program that connects to the rtsp server. 1> Can’t decode SPS at sprop-paramter-sets How do we parse “Z01AHppkBQF/y/+AXoBfNwEBAUAAAPoAADqYJ2giEag=” ? We just decode base64 and parse but width and height values was 16. Other cameras’ sps, pps is parsing normal.  We can check frame info via ffmpeg and vlc. width is 640 height 360.   2> RTSP Server does not send SPS nalu but PPS only. Intel x86 decoder we use requires SPS nalu, but server does not send.   Here is SDP.
