face=Arial><FONT face=TimesNewRoman>To avoid IP-layer packet fragmentation
(which may increase header overhead and the probability of loss due to errors),
H.264 NAL Units should be substantially shorter than the MTU size of the
network. For example, on an Ethernet network with a 1472 byte MTU, a 1200 byte
NAL Unit allows for addition of considerable header overhead without exceeding
the MTU size of the network.</FONT></FONT></SPAN></DIV>

All, <BR>Currently, my H264 plugin able to work with polycom. I found that the
media statistic(polycom PVX ) only show the frame rate video format, and display
the image if my sending encoded data is not more than 1.4KB. <BR><BR>In my code,
I do the fragmentation once it greater than 1.4KB(like libx264
do).<BR><BR>However, I had read some documentations and all of them
mentioned about H.241 only support the single NAL unit mode(mode 0).<BR><BR>I
wonder how this mode handle if encoded data greater than 1.4KB(usually
happen)???<BR><BR>Any Idea?<BR><BR>Thanks.<BR><!-- cg7.c4.mail.gq1.yahoo.com compressed/chunked Sun Nov 22 19:52:47 PST 2009 --></DIV><BR></BODY></HTML>
