SPS/PPS information into the stream.</font></blockquote>

<div>We don't insert any SPS/PPS NAL units into the stream. We
recognize them when they appear (so that they can be inserted into the
stream's SDP description (for RTSP)), but we don't insert them into
the stream; instead, we just transmit the NAL units that were in the
input file.</div>

<div><br></div>
<div>VLC seems to have a problem (in particular, with the display
window size) when playing the multicast stream, especially when the
input file 'wraps around'. I don't know what's causing this
(because VLC is not our software); you'd have to ask a VLC mailing
list about this.</div>
<div><br></div>
<div>However, you'll have better luck if you stream each file via
unicast - e.g., using "testOnDemandRTSPServer" or
"live555MediaServer". (In this case, VLC will play the
stream just once, until it ends.) That's what I recommend.</div>
