[Live-devel] [Mirasys] Live555 RTSP server questions

[Victor Vitkovskiy]

Hello Ross, 

>> But I wonder if the problem that you’re seeing is caused by the fact that the “testRTSPClient” demo application produces a line of output for every NAL unit that it receives?  This might be slowing down the client enough to lose some incoming packets?
No, it produces output for each frame, not NAL unit, so it is not a problem. I have increased buffer size on network card to 2048, now it works much better. 
I will try "openRTSP" also to see will it have some difference. 

Thank you for your help

Best regards,

Note that VLC also uses the LIVE555 library for its RTSP client implementation.  If necessary, you could look at VLC’s code to see how it’s using the LIVE555 library (in particular, if/how it calls “increaseReceiverBufferTo()”).

But I wonder if the problem that you’re seeing is caused by the fact that the “testRTSPClient” demo application produces a line of output for every NAL unit that it receives?  This might be slowing down the client enough to lose some incoming packets?

Instead, you could try running “openRTSP” instead; see
        http://live555.com/openRTSP/
I suggest running it with the -d <duration> and -Q options, so that it will output statistics (including packet loss statistics) after it ends.
