Difficulty saving channel4 on demand, 4oD, videos

[nonna]

My problems are in trying to download videos from http://www.channel4.com/programmes/4od.

Sorry for the long post, just trying to give all the info in an attempt to get this resolved.

I have found the URL of the video I want to download with URLSnooper, at least I think I have the right one. And I have what I believe is a correct command line with the correct parameters.

After finally getting RTMPSRV to work by doing the hosts file trick what I have pretty much matches with the results RTMPSRV gives.

One things that is different the URL for the SWF file. I can download the acutal swf file with the URL I get from URLSnooper but not the one the RTMPSRV gives. Regardless using one or the other does not make it work.


Using the command RTMPSRV gives here is the output

C:\rtmpdump>rtmpdump -V -r "rtmpe://ll.securestream.channel4.com:1935/a4174/e1" -a "a4174/e1" -f "WIN 10,0,22,87" -W "http://www.channel4.com/static/programmes/ass.et/flash/swf/4odplayer-4.49.5.swf" -p "http://www.channel4.com/programmes/the-italian-kitchen/4od#2924187" -y "mp4:xcuassets/CH4_08_02_16_25880001001001_001" -o CH4_08_02_16_25880001001001_001.flv

When RTMPSRV first got the command and tried it automatically I got two errors below but gets the above when I use the command prompt.

this one a few times before the command was executed

ERROR: RTMP_HashSWF: couldn't contact swfurl http://www.channel4.com/static/programmes/ass.et/flash/swf/4odplayer-4.49.5.swf

and this one most of the time after the command was executed

ERROR: RTMP_ReadPacket, failed to read RTMP packet header

Here is the command I came up. I can post the output if it will help:

C:\rtmpdump>rtmpdump -V -r rtmpe://ll.securestream.channel4.com/a4174/e1/mp4:assets/CH4_08_02_16_25880001001001_001.mp4 -a a4174/e1 -y mp4:xcuassets/CH4_08_02_16_25880001001001_001.mp4 -W http://www.channel4.com/static/programmes/asset/flash/swf/4odplayer-4.49.5.swf -o ik.flv -p http://www.channel4.com/programmes/the-italian-kitchen/4od#2924187

Both RTMPSRV's and my command both seem to stop at bottom on Failed to play (stream ID: 1).

So it seems to me that both are pretty close, and I know close really doesn't matter, it has to be exactly right. Nonetheless, I cannot get 4oD videos and I don't why. It seems that things are right but nothing seems to work. I have read and tried many, many different commands but to no effect.

Also someone stated that StreamTransport worked on 4oD videos, but I can only get it to see the ads and does not show the real video URL and thus cannot download it. Also GetFLV throws up various URLs for the video file but cannot download them, maybe I need to try some more with it. Then there was a mention of get_flash_videos. I am using Windows and can't seem to get it to take to rtmpdump, not sure if these two only work together in Linux.


If someone, who is obviously more intelligent than I, could lead me in the right direction to download 4oD videos, point out my errors or offer any assistance even if it is to let me know that it can't be done, I would really appreciate it.

Cheers


As an aside if I use 2.2c I almost always get this error

WARNING: HandShake: Type mismatch: client sent 6, server answered 8

but not with 2.1c. Not sure if this is a bug in the new version, or if it depends on the command it is given or whether or not the error matters or it's operator error.
