Hi, I am using libcurl version 7.79.1. I have an application that uses libcurl to connect to an IP camera with RTSP mjpeg stream. The application reads the frames from the camera.
The problem is, when I run this application in windows, the camera stops streaming after sending a few JPEG frames. I can verify from the Wireshark logs that the connection to the camera went through and after the "PLAY" command the camera did send a few JPEG frames. But then it just stops streaming. The connection is still active, as the camera responds to a "TEARDOWN" command with an "Ok" reply. The same application didn't give any issue in a Mac and linux OS. The camera continuously streams JPEG frames.It works with vlc media player as well on all platforms: windows, linux and mac. few other information: 1. As a heartbeat message, to keep the camera connection alive I am sending an empty GET_PARAMETER request 2. The IP camera uses digest authentication. On further investigation, I found that when the camera stopped streaming JPEG frames, there seems to be some change in the nonce used by digest authentication. Since the GET_PARAMETER request got a "401 unauthorized" reply However, the very next GET_PARAMETER request got an "Ok" reply So this change in nonce by the server(IP camera) is what might have caused the disconnection. Have you seen a similar issue? Can you help me with debugging? Regards, Vineeth Nair
