Hi so my plan was to Process some Images with OpenCV which I got from an RTSP stream.

So I'm using livemedia555 library for getting the Frames but now somehow I dont know what to do with those Frames anymore.

I got 2 different cams one stream mpeg-2 and the other mpeg-4

hope someone could give me a hint how i get Images out of those Frames now.

  • Why don't you use OpenCV library to grab frames from the stream? Here's an example on how to use VideoCapture class to capture frames from an rtsp stream: http://stackoverflow.com/questions/712998/opencv-with-network-cameras/8719192#8719192 – Alexey May 06 '13 at 13:49
  • ya I know that will be my next try if i dont get it working. but much more, I want an answer what i could do with the frames i got. and how I could use those Frames i have for further processing. – user2354773 May 06 '13 at 14:04
  • So essentially you need to figure out how to convert from livemedia555 image data type to OpenCV Mat? I'm not familiar with livemedia555 library. – Alexey May 06 '13 at 14:11
  • I dont think its any specific image data type. that should just be the frames as far as i know. i also tryed that code you linked but i just get the Error opening stream or file message. – user2354773 May 06 '13 at 14:24
  • it must have a data type. how else would a library store frames? It could store them in an array, it could be some data type specific to the library.For example OpenCV stores frame data in `Mat` class (or data type). – Alexey May 06 '13 at 14:26
  • ya it stores the data in an uint8 array but openCV does not know what it should do with them get the (-206 Error) . I get frames of different size periodically so what Google told me about that is that those are I/P -Frames so those frames are not images themself those are just compressd datas of those images if im not wrong. – user2354773 May 06 '13 at 14:33
  • maybe use your library to decode the images first. Sorry I can't help you with livemedia555 library related questions. – Alexey May 06 '13 at 14:36
