ISM Downloader - Download Silverlight videos and save as MKV files

gxdata · #1 10-26-2010, 09:16 PM

ISMDownloader is a more generic application than RTLdownloader. It allows to download Silverlight streams and save them as MKV files.

ISM Downloader is available at:

Code:

http://dvb-crew.atw.hu/applications/ismdownloader/ismdownloader2.zip
http://dvb-crew.atw.hu/applications/ismdownloader/ismdownloader.zip

Usage -

Code:

ismdownloader <manifest url> <output: *.mkv>

Obviously, this needs the manifest URL, so you will need to use an HTTP monitor application, such as Charles. There are other such utilities, of course.

I believe that the ISM utility locates the optimum bandwidth stream for your system/connection**, then downloads the fragments, and finally merges all the fragments into a final, playable .MKV file package.

** (not sure of this, or if it merely takes the highest bandwidth available on the server)

I'm trying to record videos from NBA League Pass:
http://stream-recorder.com/forum/rec...ass-t7620.html

I'm not sure whether they use Silverlight videos or not. I've tried to find manifest URLs, but not sure how to do that. An XML file that looked like a manifest forced ISM Downloader to crash.

Any idea how to record such streams?

1, install a HTTP Debugger Proxy (for example: http://www.charlesproxy.com/)
2, open the site in Firefox
3, use the filter option in Charles (type manifest in the "Filter:" field)
4, if u see an item, please send it to me somehow.

Any chance to use a simple URL finder like URL Snooper instead? May be something that is mentioned here? Or something like Live HTTP Headers or Firebug for Firefox?

i would need the manifest file. without the manifest file, i can't help you.

How do I get manifest url in Charles? I don't find any filter option. On http://www.charlesproxy.com/documentation/faqs/ says nothing...

Hello,

First of all, I would like to say that this is a great tool that does wonders for me.

Second, I'd like to ask if there's anyone out there that could build such a muxing tool to convert all the fragments, if you were to download them manually, to mkv like ism downloader does?

Last question. I've got two ism files that are practically identical, but there's only one of them that works to download from. Is there anyone out there willing to help me through PM?

I would really appreciate any help I could get.

Regards,
MB

Hi I've tried your software with rtve oogg streamings (http://www.rtve.es/londres-2012/videos/video?v=4283), and hangs every time I try to use it.

I catch the manifest url via live http headers that is, f.e.:

Code:

http://rtvelond2012vod-s.akamaihd.net/73eac305-505c-4fd4-ad3b-3537767f129b/archive.ism/manifest?__auth__=1344548435_911ef2a7996a9642cf9cf667bd916a72

the fact is, if I try:

Code:

http://rtvelond2012vod-s.akamaihd.net/73eac305-505c-4fd4-ad3b-3537767f129b/archive.ism/manifest

I get Bad Request from the server.

If I try (in firefox) the entire url, I can download the manifest file:

Code:

<?xml version="1.0" encoding="utf-8"?>

But I can only request it ONE time, if I try it a second time I get:
An error occurred while processing your request.

Reference #50.64db6ad4.1344548784.182a2653 (change with every video)

Of course I've tried both manifest urls, with and without the ?aunth=... in both cases the program (ismdownload) crashes inevitably.

Any hint?

I've tried

Hi all,

I have an issue with ISMdownloader v2.0.0.0 beta (is there any more recent version actually?)

Some smooth streaming videos I have downloaded, become corrupt while playback.

For example:

http://dme.myshowroom.tv/microsoft/6...a.ism/Manifest

http://dme.myshowroom.tv/microsoft/e...9.ism/manifest

and a couple of more examples, if anyone is interested...

Response:
HTTP/1.1 200 OK
Cache-Control: max-age=7200
Pragma: IISMS/4.0,IIS Media Services by Microsoft
Content-Type: video/mp4
ETag: "363cffc4c1b3103"
Server: Microsoft-IIS/7.5 IISMS/4.0
X-Powered-By: ASP.NET
Date: Wed, 29 Aug 2012 08:55:37 GMT
Content-Length: 26880
Via: 1.1 taurus1.sec:80 (IronPort-WSA/7.1.1-038)
Connection: keep-alive

I believe it is a MUXING issue., as the Silverlight player plays is perfectly, without any visual artifact.

I don't want to create an account and log in, but you should be able to do the following:

You need to get the URL of the file whose contents you pasted on your message/post in the other thread. That looks like the manifest, to me.

Then, you can feed that URL into ISMdownloader (use the example batch file as a model), and see what happens. Keep (copy, save to a text file) the console (screen) output, to debug any errors.
