I am having trouble downloading CSPAN video using rtmpdump (version 2.3) on kubuntu 11.4. For example, the url: http://www.c-spanvideo.org/program/MobileTechn When I try to use the parameters: rtmpdump -r rtmp://video.c-spanarchives.org:1935/fastplay/../ -y mp4:full/2011/05/19/20110519200000002_hd.mp4 -A 84 -B 3602 -W http://www.c- spanarchives.org/flash/cspanPlayer.swf -o MobileTechn_0.mp4 The dump begins correctly at 2.3%. It proceeds for a while, then drops back and redownloads a portion of the earlier stream. It will do this repeatedly as the dump proceeds so that the final file will contain many repeated segments. I used rtmpsrv to get (hopefully) better parameters. Rtmpsrv gave me the following command line: rtmpdump -r "rtmp://video.c-spanarchives.org:1935/fastplay" -a "fastplay" -f "LNX 10,3,181,14" -W "http://www.c- spanvideo.org/videoLibrary/assets/swf/CSPANPlayer.swf?rand=1249707438" -p "http://www.c-spanvideo.org/program/MobileTechn" -y "mp4:full/2011/05/19/20110519200000002_hd.mp4" -o 20110519200000002_hd.flv This gave me the same behavior. If I add the -V parameter, I observe that I get the following information at the point of the problem: 7741.721 kB / 158.22 sec (4.3%) DEBUG: HandleCtrl, received ctrl. type: 31, len: 6 DEBUG: HandleCtrl, Stream BufferEmpty 1 DEBUG: HandleCtrl, received ctrl. type: 1, len: 6 DEBUG: HandleCtrl, Stream EOF 1 DEBUG: RTMP_ClientPacket, received: invoke 208 bytes DEBUG: (object begin) DEBUG: Property: NULL DEBUG: (object begin) DEBUG: Property: <Name: level, STRING: status> DEBUG: Property: <Name: code, STRING: NetStream.Pause.Notify> DEBUG: Property: <Name: description, STRING: Pausing full/2011/05/19/20110519200000002_hd.mp4.> DEBUG: Property: <Name: details, STRING: full/2011/05/19/20110519200000002_hd.mp4> DEBUG: Property: <Name: clientid, NUMBER: 504348861.00> DEBUG: (object end) DEBUG: (object end) I have found that if I use the --live parameter, the behavior improves, although I get occasional video corruption. Is there anything that I can do to fix this problem?
