More than 32 streams in a windows media file ekta91com 10/7/2008 10:51:01 AM Hi, I am working for the European Parliament on a project for recording session with more then 32 languages in a Windows Media file. I produce a windows media file with 3 video streams (in multiple bitrates) and 30 audio streams mutualy exclusive by language (available on http://ektacom.vous-assiste.com/?ppz=4e42c881-5515-4748-8c5a-4e100732d21b&ppa=ppav&ppt=dl&pppk=44&pg=pvpn). I put this file on Windows Media Server (2003 SP2) and try to play it with the WMP 11 throuh mms : that fails with error code C00D1197. I produce another windows media file with 3 video streams (in multiple bitrates) and 29 audio streams mutualy exclusive by language (available on http://ektacom.vous-assiste.com/?ppz=4e42c881-5515-4748-8c5a-4e100732d21b&ppa=ppav&ppt=dl&pppk=43&pg=pvpn). The file plays very from a WMS through a mms URL. Another info : the 2 files play very well in the WMP 11 directly from the disk (file reading). Is there a limitation in the WMP or in the WMS ?

That's NS_E_WMP_CANNOT_FIND_FILE, which is weird. [...] > Is there a limitation in the WMP or in the WMS ? The ASF file format supports 127 streams. The WMF runtime supports 63. The MMS protocol supports 65564. WMS *seems* to be (un)limited to 4Gi of streams. So I really can't see where the 31 stream limit comes from (since it works in WMP when played locally, my guess would be a limitation either somewhere in WMS or in the MMS receiver bundled with WMF). -- // Alessandro Angeli // MVP :: DirectShow / MediaFoundation // mvpnews at riseoftheants dot com // http://www.riseoftheants.com/mmx/faq.htm

Re: More than 32 streams in a windows media file ekta91com 10/8/2008 9:45:02 AM I agree with you : the WMReader object from the WMF SDK has a limitation and/or the WMS parser has one also. What can I do ? I'd like that someone from MS can test my files and see what's hapening in the player and server ? -- Olivier "Alessandro Angeli" wrote: [Quoted Text] > From: "ekta91com" > > > I put this file on Windows Media Server (2003 SP2) and > > try to play it with the WMP 11 throuh mms : that fails > > with error code C00D1197. > > That's NS_E_WMP_CANNOT_FIND_FILE, which is weird. > > [...] > > Is there a limitation in the WMP or in the WMS ? > > The ASF file format supports 127 streams.

The only way to get in touch with MS people is to contact PSS and hope they will, sooner or later (most likely later, as in several days later), escalate to the unreachable WM group. If they find out it is a bug in their code, the support call should be free of charge. http://support.microsoft.com/ -- // Alessandro Angeli // MVP :: DirectShow / MediaFoundation // mvpnews at riseoftheants dot com // http://www.riseoftheants.com/mmx/faq.htm
