FFMPEG error with avformat_open_input returning -135
问题 I have a DLL one of my applications uses to receive video from RTSP cameras. Under the hood, the DLL uses FFMPEG libs from this release zip : ffmpeg-20141022-git-6dc99fd-win64-shared.7z We have a wide variety of cameras in house and most of them work just fine. However, on one particular Pelco Model Number: IXE20DN-OCP, I am unable to connect. I tested the camera and rtsp connection string on VLC and it connects to the camera just fine. I found the connection string here : http://www
