Thank you for writing rtmpdump. I repeatedly, yet randomly, get the following error, upon which rtmpdump hogs the cpu and freezes. Unfortunately, I lack the time and skill to debug: INFO: sampletype mp4a 22437.187 kB / 302.22 sec (9.7%) ERROR: RTMP_ReadPacket, failed to read RTMP packet header 22529.357 kB / 303.00 sec (9.7%)^C Caught signal: 2, cleaning up, just a second... 22529.357 kB / 303.00 sec (9.7%) Download may be incomplete (downloaded about 9.70%), try resuming dan@dan-desktop:~/temp$ The download is: dan@dan-desktop:~/temp$ rtmpdump -r "rtmpe://hulu-397.fcod.llnwd.net:1935/a4957/o23?sessionid=3CA0DE7F115B009C995946CDC47E0F6C&as=adobe-hmac-sha256&av=1&te=connect&mp=397/14807397&et=1288052238&fmta-token=3ab79268b5dab78ba15693dc9e6178efdd8b6b9a286f3150da2d18791ed4c5b4&hgt=OZU7Pvs7j27-nhteNno7woZqhcc7ia3k8M_xloEhE-5YysCIjxOchOUtyemGcN1F2WmZ59bGDqJUBQuaiULGKQlFGpLFusKdGI3JtU9U9gQG45Yf86pOnKcOmsZOKdj93PPcNPxOgCqkI8rW1-moR5s8nQvX4AlDGWWPHPESwcp7itc9gEiaZqA8RzKa4AD_i3fRvfN2ngVdnG7IAc7qdytsfdn_gq_tF3oxBULZjgsr8a3MZW19Bkz09B-cWTGlGOwWv1N5wnhVf0enKoHp0RDyhXmiRXceR67FqxeH3YA0DJ4AjykdasfFw4ctvuT2&hgt_ver=331370278" -a "a4957/o23?sessionid=3CA0DE7F115B009C995946CDC47E0F6C&as=adobe-hmac-sha256&av=1&te=connect&mp=397/14807397&et=1288052238&fmta-token=3ab79268b5dab78ba15693dc9e6178efdd8b6b9a286f3150da2d18791ed4c5b4&hgt=OZU7Pvs7j27-nhteNno7woZqhcc7ia3k8M_xloEhE-5YysCIjxOchOUtyemGcN1F2WmZ59bGDqJUBQuaiULGKQlFGpLFusKdGI3JtU9U9gQG45Yf86pOnKcOmsZOKdj93PPcNPxOgCqkI8rW1-moR5s8nQvX4AlDGWWPHPESwcp7itc9gEiaZqA8RzKa4AD_i3fRvfN2ngVdnG7IAc7qdytsfdn_gq_tF3oxBULZjgsr8a3MZW19Bkz09B-cWTGlGOwWv1N5wnhVf0enKoHp0RDyhXmiRXceR67FqxeH3YA0DJ4AjykdasfFw4ctvuT2&hgt_ver=331370278" -f "LNX 10,1,85,3" -W "http://www.hulu.com/site-player/74336/playback.swf?cb=3.0.1.74336" -p "http://www.hulu.com/watch/63084/the-outer-limits---original-galaxy-being?hul..." -C Z: -y "mp4:397/14807397/HuluTranscode_73006_100488_28647_4x3_24fps_H264_650K.mp4" -o HuluTranscode_73006_100488_28647_4x3_24fps_H264_650K.flv Of course, I only download because the flash player works so poorly, not to steal or share video. Thanks.
