How i can get stream from Ip Camera, Its using RTP, stream is MPEG4, i have multicast address and port,and i have ip camera's IP address and Port Number.
And I cant reach via http forexample (http://ip/jpeg) And I cant reach stream with VLC Player too. forexample (rtp://ipadressofcam:port) and (rtp://multicastaddress:port)
So What is ffmpeg command of that?
I have windows OS, I only write code with C# right now.
But producer created their own ocx which used for viewing cam,that plugin can work on .net but i dont want to use it becouse it doesnt have much funcionality, I mean you cant get current picture or snapshot of cams, thats why i have to do it myself.
Are you sure the stream is not password-protected?
Try to see why your camera rejects VLC requests. And this is how to do it: Install Wireshark, start it, and put a filter for the camera address, like: ip.addr == camera_ip (xxxx.xxxx.xxxx.xxxx). Then, try to connect with VLC, and look there at the messages exchanged. If you see a DROP, UNAUTH, or something that tells you to use a passwd, introduce it. (VLC will first try to connect using an unauthenticated procedure, and if it fails, will ask for a passwd.)
Wireshark will give you clues if the failure reason is something different.
And keep in mind that if VLC can't access it, the chance to find some other way to do it is almost zero. Unless you're a video guru.
Hope it helps!
