software to capture microsoft's new silverlight (?)

Re: software to capture microsoft's new silverlight (?)

 

first of all,the resulting file converted with the version 1 of smooth streaming is an ismv file and not a mp4 file,that thing that i not understand is that the difference between aren't many,the fragment that i sniff with wreshark aren't encript,infact with mp4 explorer is clearly visible the moof and mdat boxes...

i don' t know the library for the source code and how to join the segment,but i think that if this has been maked for the version 1 i don't understand what is the problem for the version 2...the box ftype contain the codec avc or h264,all the other segment are easy to find...is sufficient use microsoft encoder 3 and make only a project to see that in the ismv file there only some information and all the box(2 box: moof and mdat) for each segment

Re: software to capture microsoft's new silverlight (?)

 

ismv chunks differ in quality and cannot all be combined into a single file. So it is not that easy to combine those chunks and place them into an MP4 format.

Re: software to capture microsoft's new silverlight (?)

 

when you see the streaming to the browser then the chunks can have a different bitrate,but nobody prohibits the forced download(with a simple download manager considered that silverlight use http protocol) of all the chunks with the same and the highest bitrate(is sufficient set every url for each chunk with the highest parameter of bitrate founded in the manifest file)...now,the think that i want,and that has been implemented in Replay Media Catcher 4 (Jaksta) and that worked only with release 1,is the creation of the original ismv file...to the server,for each bitrate in manifest file,is present an ismv file with the same content but different resolution and bitrate.... rmc 4 (jaksta) work fine with release 1,infact build only an ismv file with the highest bitrate(contrary to that you have write,jaksta merge all the chunk in a single ismv file) ...the thing that i don't understand is why isn't possible make the same thing with release 2 or highest...finally,consider that the ismv file structure isn't the same of mp4 file structure,but this for me isn't important infact i can view the ismv file quietly with windows media player....

Don't know where you get these details, but you are correct :)

Ismv is mp4. Its just chunked. But that is not the issue. The issue is with the codec details sent in the manifest and which box to place them in. Can you help with that?

How do you play ISMV files with WMP?

Re: software to capture microsoft's new silverlight (?)

 

the ftyp box is the codec used (avc or h264),the track are only 2,one for the audio and the other for the video...all the data of the box moof and mdat must be simple copy and pastes in the ismv file...the other details i don't know,but i don't think is very difficult make the ismv file...maybe there is a detail that I don't consider,but i see that the details in the manifest file of release 1 are the same of the detail in the release 2...the only difference that i see is how are managed the chunk,when major version is 1:
<c
n="0"
d="20000000" />
<c
n="1"
d="20000000" />

the attribute d(duration) of the tag c(chunk) is constant while when the major version of the manifest file is 2 the chunk are managed in this way:

<c
t="509800000000" />
<c
t="509820000000" />

for the bitrate the attribute of the tag QualityLevel are the same...

did you work in the jaksta developer team?

for windows media player i don't remember how I have maked to enable the view of ismv file,if i find the decoder file(.ax or .dll) i send it to you...maybe the view is enalbed when i setup he microsoft encoder expression 3 pro,but i'm not sure...

Re: software to capture microsoft's new silverlight (?)

 

I contact the developer of RMC 4 (Jaksta) as well as some other developers on a regular basis.

May be microsoft encoder really did the trick.

Hi,
I've just wrote a CLI program in C# which can download Smooth Streaming Media and can mux it to MKV.

If you want to test my program. It is available on:
http://dvb-crew.atw.hu/applications.php
it was designed to download streams from http://www.rtlklub.hu/most/, but its engine is might useful to solve your problems too.

If you can help me, please contact me on MSN:
kissda@primposta.com

Thanks in advance!

Re: software to capture microsoft's new silverlight (?)

 

Replay Media Catcher 4.0.17 and Jaksta for Mac 1.0 support Smooth Streaming MajorVersion 2. Tried to download from MSN Video and other web-sites. Works fine for me.

search term < applian updates > and the first google hit is:
http://www.applian.com/blog/updates/

it is my favourite ;) news site
and makes me wonder why RMC4 is updated so frequently. RMC3 was rarely updated :rolleyes:

good job everybody

@zoldike
Hi, I'm attempting to bulid something like your ismdownloader2 for Linux. To avoid using Moonlight plugin on my browser. I've built a rough downloader, rebuild the video part and played it by Mplayer.
But I'm having problems with the audio part. The manifest indicates a WMAP codec. Can you explain which steps you follow to rebuilt and merge the audio chunks into a playable audio stream?

tks in advance
