I have hikvision camera that has video encoding in H.264 I m wondering that if I could live stream that video in Matlab. Or it is possible to do with vlc video player.

Hi Haris,
MATLAB will be supporting H.264 encoded RTSP streams for IP Cameras through MATLAB Support Package for IPCameras in the upcoming release, MATLAB R2020b version. Hope it helps!

tal mazor:
You cannot do that. R2020b is the first release that supports rtsp H.264 . Releases before that only support RTSP for Motion MPEG at most.

Historically it has not been possible to live stream h264, but I have not rechecked the latest two releases. I cannot presently rule out the possibility that a recent change to support for one of the boards such as arduino might perhaps have added the capability; it was not there in R2017a (not without running a custom adapter)
Devices such as gigabit cameras return entire frames in the mode supported by MATLAB, rather retuning h264 streams with some hypothetical function to decode the frames.
The historical support for h264 has only been from file, not streaming.
If you have Windows then you can use activexserver to talk to a COM object to do the decoding for you and to return the frames.

Hi Tal,
You can use the following documentation to troubleshoot the connection issue:
Troubleshooting Connection Issues to the IP Camera
Ensure that the authorization is set to basic and not digest in the camera software settings. For further help please reach out to MathWorks Technical Support.
