Troubles reading a stream which reads perfectly WindowsMedia

[Suricat]

Hi folks,

I've browsed FAQ and doc, search this forum but not found my solution.... I don't get why this doesn't work.

I'm trying to read this stream : http://stream.babiel.com/pusheuat4_1804a.wmv (via). It reads well from Media Player but I can't get it with VLC....

From the logger file I get these (I tried to keep only revelant parts, but I may have miss important information. I can supply a long/full listing if required). I don't understand the origin of HTTP/1.0 400 Bad Request

What surprises me is it works with Windows Media Player

Sorry this is my first message here...

If anyone has a clue...

What version of VLC?

Version innfo can be found in the Help tab. Plaese don't say the current version.

[Suricat]

It is on the first line of the "code" section

logger: VLC media player - version 0.8.4a Janus - (c) 1996-2005 the VideoLAN team

Is it enought ?

[DJ]

You might try 0.8.5 Test 3 as I believe the mmsh section has been rebuilt.

http://downloads.videolan.org/pub/video ... 8.5-test3/

[Suricat]

With 0.8.4a in the message windows I had

Code: Select all

access_mms error: error: HTTP/1.0 400 Bad Request access_mms error: cannot start stream main error: no suitable access module for `mmsh://stream.babiel.com/pusheuat4_1804a.wmv?MSWMExt=.asf' access_mms error: error: HTTP/1.0 400 Bad Request access_mms error: cannot start stream main error: no suitable access module for `mmsh://217.79.215.188:80/pusheuat4_1804a.wmv?MSWMExt=.asf'

with 0.8.6-test3 I have

Code: Select all

access_mms error: failed to send command access_mms error: failed to send command access_mms error: failed to send command access_mms error: failed to send command access_mms error: cannot connect to server access_mms error: cannot read data access_mms error: error: HTTP/1.0 400 Bad Request access_mms error: cannot start stream main error: no suitable access module for `mms://stream.babiel.com/pusheuat4_1804a.wmv?MSWMExt=.asf'

(which is almost the same)

I've done the test again at the same time with Windows Media 9.00.00.3344 and it works.

Seems it looks like a protocol mismatch, I did an Ethereal capture of the two connections which are really different.

VLC
It starts with a really simple HTTP request

Code: Select all

GET /pusheuat4_1804a.wmv HTTP/1.1 Host: stream.babiel.com User-Agent: VLC media player - version 0.8.5-test3 Janus - (c) 1996-2006 the VideoLAN team Range: bytes=0- Icy-MetaData: 1 Connection: Close

and receives

Code: Select all

It then tries to connect to port 1755. First it receives a RST immediately, then i sends a MMS packet but still receives a RST.

Then it switch back to HTTP

Code: Select all

This connexion closes normaly.

A last there is this request :

Code: Select all

The main differences I can see is the user agent (User-Agent: NSPlayer/4.1.0.3856 vs User-Agent: NSPlayer/9.0.0.2980) and the fact that when VLC connects with the user agent it tries with and URL completed with "?MSWMExt=.asf " which might be the reason of the "Bad Request" answer....

Well... If anyone has an idea....

(sorry for this long post)

Interesting! You have obviously done some research here. I would like to know the answer too.

[RomkaFromUA]

Hi) Trying to work with WMS and have also some problems similar to yours.

I'm working with WinHttp, and it seems that it'll be unreal to use it to get stream like Windows Media does (((

If any of my thoughts are interesting (who knows? ) or you've reached some results in your work and think you can help me, you may mail shmromacs@yandex.ru.

thanks bye

[Suricat]

Unfortunately, I did had any more answer on this topic. I've managed another wy of reading this feed with WMP....

[RomkaFromUA]

Hi again )) Fate plays games, and I'm again on this forum )) so... I've created a program, that is attackin' WMS with a number of requests using sockets and IOCP... so ... maybe it'll be useful for you

[DJ]

While I'm getting a bit different error report than you are it doesn't work for me either using VLC.

I most certainly would not say "perfectly" as there are black lines randomly running through the video and the right side of the video shows distortions. This is not well encoded video.

[pdoru]

look here:

Pragma: stream-switch-count=2

Pragma: stream-switch-entry=ffff:1:0 ffff:2:2 ffff:3:2 ffff:4:0 ffff:5:2 ffff:6:2


how many streams do you count ? i count 6. while only 2 are active, there are 6 streams in the switch entry descriptor.
