Work Note
Test site: http://tiv-dmz.homeip.net/VQG/?menu=VQG.MSM
Steps:
1. Click 0: MSM.1-6 - Basic Video Streaming
2. Click 7: SDP H.264 192kbps AACPlus 24kbps QVGA 10fps (to RTSP redirect)
The link is:
http://tiv-dmz.homeip.net/content/sdpgen/h264_192kbps_aacPlus_24kbps_3sec_QVGA_10_fps.sdp?redirect=1&sessionID=18p6849Bvnr2QEtj

If we click this link in Chrome/Firefox in Ubuntu desktop, a pop-up window appears to ask for launching application. If we choose VLC media player, it can play the streaming video with the following RTSP link:
rtsp://tiv-dmz.homeip.net/h264_192kbps_aacPlus_24kbps_3sec_QVGA_10_fps.3gp?redirect=1&sessionID=84KmiejPeKLOiyxd

Previously, http->rtsp redirection would cause a system crash.
Fortunately, the fix of bug 949667 prevents such undesirable crash. For now, http->rtsp redirection just doesn't work and the browser would display a "Moved Permanently" message.

Furthermore, bug 949675 (Implement IPC for RtspChannel to support redirects and be generally correct) should totally resolve http->rtsp redirection issue. Therefore I will set this bug as a duplicate of it.
