[Live-devel] OpenRTSP Frame Loss When Streaming Multiple Cameras

[Ross Finlayson]

> I am seeing an issue when running multiple instances of openRTSP to capture h.264 data from multiple IP cameras.  I am using command line options to allow openRTSP to save the data into 12 second periodic files.  I have openRTSP compiled and running on QNX 6.5.0 and can stream data from one and two cameras with no issues.  When I stream with 3 or more cameras however, I notice the library is not receiving all the frames.  This grows worse the more cameras (and subsequently instances of openRTSP) I am streaming from.

No.  The problem is insufficiently large buffering in the receiving computer's OS.  See:

and note, especially, the last paragraph.
