Problems to download cbc.ca streams/replays

[curseknight]

Hello guys,

I have been able to download every single stream/video I've encountered so far, except this one. But I know it's possible to rip it, because I've seen a few videos from that channel available for download.

Trying to download this video, which is actually the replay of a stream. Tried every piece of software and it does not recognize it. RMTPDump, RMTPDump Helper, Replay Media Catcher, HiDownloader, and others.

URL Snooper only gets a bunch of .ism files with the same title and very small size.

I haven't found that specific one for download anywhere else, either, so can you guys help me with it?

Thanks!

cbc uses a different format for their olympics video..they use silverlight and it's not supported by most downloading programs..
you have to use ismdownloader,
then you have to open up the downloaded manifest file,
change a few things, etc..
not straightforward at all...

klatwork: can you explain the opening of the manifest file, changing a few things, etc. I am interested and looking to do the same thing.

I'm no expert in video downloading..but i played around with the program and finally figured it out....

ismdownloader looks for the highest quality video stream and tries to download it..but the highest quality video stream isn't available for the first few fragments , so ismdownloader runs into an error and skips over the video stream and downloads only the audio stream....so you'll have to open up the manifest, change the start time for the both the audio and video stream....
the start time looks like this <c t="1xxxxxxxxx" ...

timestamps for the segments.you can see them when you open up the firefox console ctrl-alt-k

Hello.

I am too trying to download an event from cbc:

http://olympics.cbc.ca/videos/live/v...a-webcast.html

It is quite long, 2,5 hours and that causes problems.

I tried using ismdownloader. But since I am not in canada, I have to use vpn to access the site and the download is so slow that the connection breaks before ismdownloader finishes. So I am left with lots of fragments of audio and video.

I downloaded the missing fragments using DownThemAll batch downloader, so I have the whole file, but in small chunks.

I am stuck at this stage.

Ismdownloader can not be used to join the fragments, since it does not have any option allowing just merging of the chunks, but not downloading them first.

I tried using the AdobeHDS, but it says "Unknown packet type 0 encountered! Encrypted fragments can't be recovered.". I think it just does not work with silverlight fragments, since it says the same for fragments of a shorter video ismdownloader does just fine.

I tried to find ismdownloader source to find out how it does the merging, but no luck. I couldn't find any other program that works with silverlight streams from cbc. Tried jaksta, replay media catcher and a few others and nothing.


Any ideas?

I don't insist on cbc, but since I don't have a US cable subscription, nbc is not an option.

Thanks in advance.

If this is the same event on nbc;

http://stream.nbcolympics.com/curling/winter/14756/

You can use ffmpeg, no auth required;

ffmpeg -i "http://olystreameast.nbcolympics.com/vod/cb8131cb-722a-44b7-bd1e-8e477f58a43a/curling--swe-chn0220232343.ism/QualityLevels(56000)/Manifest(audio_en_0,format=m3u8-aapl)" -i "http://olystreameast.nbcolympics.com/vod/cb8131cb-722a-44b7-bd1e-8e477f58a43a/curling--swe-chn0220232343.ism/QualityLevels(3450000)/Manifest(video,format=m3u8-aapl)" -c copy t.ts

Note: This video contains a lot of useless portions with "event starting soon" as the video.

To the OP, your link seemed to be pointing to the CBC replay of the Figure Skating Pairs Free Skate. If so, I was able to download it using the following ffmpeg command.

ffmpeg -i "http://olystreameast.nbcolympics.com/vod/1cc05896-0fba-473d-b426-f1076ad456b7/pairs-free-skate0212064340.ism/QualityLevels(56000)/Manifest(audio_en_0,format=m3u8-aapl,filtername=vodcut)" -i "http://olystreameast.nbcolympics.com/vod/1cc05896-0fba-473d-b426-f1076ad456b7/pairs-free-skate0212064340.ism/QualityLevels(3450000)/Manifest(video,format=m3u8-aapl,filtername=vodcut)" -c copy "PairsFree.ts"

The actual program starts at Frag561, so the first 30 minutes or so of the file can be skipped.
