I recommend testing your URL directly in the player when you find errors you cannot explain. The player is for testing, since sometimes what you have in the code may be wrong. lib files, so you will have to find these and link them. I needed the libvlc.dll, libvlccore.dll, the headers and the. Then link them, almost exactly like you installed and linked OpenCV (I used local method: system paths and environmental variables, after which I had to reboot). So I downloaded and installed libVLC along with the VLC Player.Ī) libVLC installation: Download the 7zip file (no installer version) so as to get all the library header files, DLL's and source codes. This is not a problem for my application since I just need to process them together, not display them simultaneously.ġ) It seems clear that FFMPEG library does not work for H264 video streams over RTSP. I need to figure out how to display them separately instead of alternating on the same window. The video stream of 2 cameras works with the following minor issues: I am using Visual Studio on MS Windows 7 and 8.1 machines and coding in C++. I've posted the question and the solution so others don't have to search through many other posts that don't quite solve the issues I've had, and to share details that I had to figure out which helped me.
and a new update should fix it for 3.0.0 see this bug report) and did not work for me.Īfter summarizing my question and struggles, here is the answer and solution I've come up with so far. Trying to do the TCP protocol instead of UDP may have fixed the issue for others, but this is already incorporated in the latest versions of OpenCV (it was for 2.4.11. VideoCapture cap1("rtsp://username: :554") Ĭap1.open("rtsp://username: :554") īecause of the broken video feeds from FFMPEG as explained above. I wanted to use my OpenCV code but could not just use: I have multiple IP cameras that I connected to a switch, and then need to process the video feeds through the rtsp commands that was given by the camera manufacturer: "rtsp://username: :554" (Here, 554 is the RTSP port number assigned to the camera, which may require you to go an adjust the number by logging into the camera and accessing the camera settings) It appears that others have struggled as well, since OpenCV uses ffmpeg library for rtsp and such, but has decoding errors for at least h264 video streaming (See link1, link2, link3 for some examples of broken images). Mainly I am doing this to help those that have this issue or will face it in the future, so they don't have to waste valuable time. I've been struggling with this for a few months now and thought I should consolidate my efforts and "research" into this question all in one place.
