Hi,

Quicktime is not playing the live stream given by the SDP file generated on
running testMpeg4VideoToDarwin. I am using Darwin Streaming Server 5.5.1 on
Windows XP.

I have made the following observations:

1. On ethereal, the SDP in the rtsp response shows [Unreassembled Packet
[Incorrect TCP checksum]: SDP] after the

a=x-qt-text-aut: field in the SDP document.

2. On checking the timestamps in the RTCP Sender Report packet, it appears
to have an invalid NTP timestamp. Ethereal dump snippet is as follows :

Timestamp, MSW:3352707798

Timestamp, LSW:2306397438

[MSW and LSP as NTP timestamp: Not representable]

RTP timestamp: 1046117017

Any help on what could be the reason of this problem is appreciated. Also,
is there a need to change the timestamp generation in the
testMpeg4VideoToDarwin executable?

Regards,

Aloka
