preview and capture using RTSP_LowLatency source

Sep 09, 2021
Jonathan Spiegelglas wrote
I've successfully used the "IP camera capture to MP4" example to preview and capture a video-only stream from my security camera. In my use case low latency is extremely important so I switched to the RTSP_LowLatency source, however the app simply hangs when I hit the start button. Is there any prerequisites I need to install on my machine before using it?

I'm using the 64bit version of the SDK


Thanks

Hi

Does the same URL work with LAV or FFMPEG engine?

Have you checked both TCP and UDP protocols?

It was something to do with the frame rate. Once I forced a fixed FPS it started working.

Thanks

That could be a problem if the camera does not provide a frame rate value (but the camera should provide it for the RTSP).
