<div>AXIS camera doesn't give NALU 7 and NALU 8. So RTSP has no issues with the streaming only the parsing and decoding at the receiving end have issues.</div>
<div>Try to see what is the NALU unit type you are receiving from the url.</div>
<div>Thanks and Regards,</div>

<p>Hello,</p>
<p> </p>
<p>Our company has been using the Live555 streaming library in a custom DirectShow source filter for well over a year. We handle cameras from many vendors, in multicast and unicast, without issues. However, we noticed a problem with Axis cameras, configured for streaming H264 in multicast: </p>
<p> </p>
<p>- When multiple connections are attempted simultaneously on different Axis devices (via multiple instances of the source filter), sometimes the client application will close unexpectedly. It's a silent shutdown; no exceptions are caught by the source filter/Live555 lib; no errors are logged.</p>
<p> </p>
<p>Further observations:</p>
<p> </p>
<p>- More simultaneous connections = higher incidence of crash</p>
<p>- It happens sometimes in unicast, but very rarely.</p>
<p>- It happens regardless of the other filters in the DirectShow graph (CoreAVC, ffdshow, DivX, VMR7, VMR9, EVR, etc).</p>
<p> </p>
<p> </p>
<p>Admittedly, the crash could happen in our own source filter code and be unrelated to Live555... but our source filter code is unaware of specific camera vendors...</p>
<p>Also, we are using the Live555 streaming library from 2009, but it contains the typical fixes for Axis (ex. getting the ports/addresses from RTSP SETUP, not from RTSP DESCRIBE).</p>
<p> </p>
<p> </p>
<p>This is really puzzling... I really hope someone can help us on this.</p>
