You can fix it by demuxing the file and remuxing into a .mp4 container or a new .flv container

You must be inadvertently confusing me with a geek. As someone who gets out a lot and has a real life to get on with, "remuxing mp4 containers" is not something I can find a timeslot for. Thanks anyway.

I avoid categorization and generalization of people. You somehow wound up posting at this forum and I offered a solution.

Fixing (remuxing) takes around 5-15 seconds at most. GetFLV does the hard part (downloading the file). You likely won't find any other way to download from channel4. So if you give up that easy - at least it frees up a timeslot for you.

Thanks for posting this information. I had been seeking a way to download Channel 4's shows.

I wonder whether GetFLV will work with ITV and BBC streaming videos also? I will find out when I have the time.

Cheers.

Success here - I'm an expat using a slow VPN connection. I used the trial version of GetFLV 8.8.46.

I downloaded 10 MB (trial limit) of Derren Brown and then extracted the .264 with FLV extract.

I used WinFF to extract the ACC and convert to AC3 then muxed the H264 & AC3 streams into a MKV container using MeGUI to play on my XBOX running XBMC. (Xbox is not fast enough to decode AAC) - it plays fine.

PS - I also tried the as-downloaded .FLV file on the xbox using the built in DVD player and it appears it would play at the right speed if it didn't struggle with the AAC codec - so are there PC based players that would play the FLV stream at the correct speed without the demuxing/muxing...?

I've just found a version of youtube-dl (attached to last message on

Code:

http://bitbucket.org/rg3/youtube-dl/issue/63/support-for-4od-http-youtubecom-shows

) which allows downloading rtmp streams from youtube, including all the 4od shows there. Result!

Let us know which programs don't work and what kind of errors exactly you get with them when downloading from 4od:

You can check what programs support RTMPE streams in the following thread:

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

Code:

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

Code:

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

Code:

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:

Code:

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

Code:

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.

get-flash-videos is a perl script; as long as you have perl and rtmpdump installed properly the script will run on any machine.

The note about the Handshake type mismatch is only a WARNING, not an ERROR. You can safely ignore it in this case. (A type 6 request can validly get 6, 8, or 9 in the reply. Other values would probably indicate an actual problem.)
