The latest version of GetFLV (Version 9.0.0.0) is (again) able to download CHANNEL4 / 4OD videos, such as

Code:

http://www.channel4.com/programmes/supersize-vs-superskinny-kids/4od/player/3173283

the full-length streaming url is something like the following and includes your ip address and downloads either through port 1935, 80, or 443; the streaming server is ll.securestream.channel4.com or ak.securestream.channel4.com or similar:

Code:

rtmpe://ll.securestream.channel4.com:1935/a4174/e1/?ovpfv=1.1&e=1301305313&ip=93.96.179.128&h=4db6b4ec4d0b2b7e1e46d9f892875e2a/?e=1301305313&ip=93.96.179.128&h=4db6b4ec4d0b2b7e1e46d9f892875e2a
rtmpe://ll.securestream.channel4.com:443/a4174/e1/?ovpfv=1.1&e=1301342335&ip=178.238.142.242&h=36aca5121fb2a95a96a2bceb48a19cd0

Then GFLV captures all kinds of different rtmp/rtmpe streams, some url's for the commercial ads and ~2 url's for the actual video. Try to download the 2nd video url! Two typical situations are the following (and delete the ads url's!):

Typically only one video url downloads well. And, you can download several videos at a time (here: Come Dine With Me)

rtmpdump doesnt download! (see screenshot)

Code:

rtmpdump -r "rtmpe://ll.securestream.channel4.com:1935/a4174/e1/?ovpfv=1.1&e=1301315907&ip=77.246.173.28&h=2b5230e50260319c5f11b10c239d25d7" -a "a4174/e1/?ovpfv=1.1&e=1301315907&ip=77.246.173.28&h=2b5230e50260319c5f11b10c239d25d7" -f "WIN 10,2,152,32" -W "http://www.channel4.com/static/programmes/asset/flash/swf/4odplayer-4.85.2.swf" -p "http://www.channel4.com/programmes/supersize-vs-superskinny-kids/4od/player/3173283" -C Z: -y "mp4:xcuassets/CH4_08_02_900_47177002001001_002.mp4?e=1301315907&ip=77.246.173.28&h=2b5230e50260319c5f11b10c239d25d7" -o CH4_08_02_900_47177002001001_002.flv

channel4 is a bit harder than itv. so here another proof (screenshots), ta-rah!

GOOD NEWS. getflv posted an updated version on their website (today!!):
GetFLV Version 9.0.0.0,
and with it i was able to download the video!!

the FIRST (line#1) and the LAST line (line#6) belong to the same (actual) video clip. the url's in between, lines #2-#5, belong to the ads (commercial clips of ~40secs length). i waited until all ads were gone and until line#6 appeared. then "Download" and GFLV begins to download the video without problems.

GFLV downloaded the following url:

Code:

rtmpe://ll.securestream.channel4.com:80/a4174/e1/?ovpfv=1.1&e=1301338326&ip=178.238.142.242&h=b7e0c6f007f45b95f92a06f11929438f

!!GREAT JOB AND BIG THANKS GOES TO THE GETFLV SUPPORT TEAM!!

Please, could you inform how to get this version?

I just want to thank Placebo for grabbing something off ITV Player for me on Sunday night [despite it being late]
He used GetFLV - I might look into it as nothing else seems to work any more.
I just cannot get my head round this rtmpdump thing, even though I have downloaded all the bits and pieces for it, including something called Strawberry Perl, but I can't figure it out and just haven't got the time or concentration to learn at the moment

the only thing is, the videos I got in flv just wouldn't convert to avi or MP4 in Daniusoft Video Converter Ultimate, or Any Video Converter Professional - and the first one usually handles anything.

So I had to use ConvertXtoDVD to convert the flv's to DVD format
and then use Auto Gordian Knot to get avi from them so I could join the 2 parts - as you can imagine, this took many hours and I couldn't use my computer for other things while it was being done,
but the quality was ok [infact the quality on the original flv was excellent, I was quite surprised]
so thanks again, Placebo

@nonprofit, thanks for your report and kind words. was a pleasure to help (since, maybe, not too many own a purchased copy of GFLV.); just the FREE proxying thing (i've tried various types A, B, C, etc.) was killing me

Conversion of media files is discussed here:
http://stream-recorder.com/forum/con...files-f16.html

Conversion causes a degradation of quality (because none can be better than the original

). To minimize quality loss, the video and audio tracks could be extracted losslessly with FLVExtract and then you could put them back together joined in a *.MP4-container or *.AVI-format. Replay Media Catcher can do conversions and extractions too .. but these itv FLV-files are quite something!

I've never done joining of video parts before so i cant help here. I would probably try to do everything in Nero 10.

you can join FLV-video parts with FLV Joiner (freeware):

WM Capture 5 can capture video from screen into DVD-Video .ISO file. No need to convert for hours.

I only had to do that because I wanted an avi actually [to upload for someone who is abroad and can't see ITVPlayer]
although I can use the resulting DVD files now to burn a copy for myself

I've tried a screen capture thing and the frame size was confusing to me, and how it kept mirroring/reflecting what it was doing [sorry, I can't explain, but it's not the way for me]
