Could you tell us the correct sdp fmtp line to

<div>No I can't, because only you know the details of your H.264
stream.</div>

<div>Are you sure you are encoding the sps and pps NAL units correctly
using Base64 (for the "sprop_parameter_sets_str"
parameter)? I suggest that you go through VLC's LIVE555
interface code (in "modules/demux/live555.cpp") to make sure
that the SDP fmtp string is decoded into the correct NAL unit data
(see the function "parseH264ConfigStr()").</div>

<div>If you're still having problems, then you may need to make your
RTSP stream publically available, and post to the VLC mailing list,
asking them why VLC cannot play it.</div>
