The VideoLAN Forums

Dear Forum,

I have tried exhaustively to get mms streaming to work consistently and have not had luck. A few times the display worked immediately, but usually it either takes about 1 minute or fails. Appears this problem has been encountered before, but not sure if a fix was implemented.... Based on those posts its appears it revolves around an issue" with LIBACCESS_MMS.DLL. I downloaded a more recent version of this dll but crashed vlc when I used it... One post suggests that there is an extra or missing "/" in the mms path specification from the receiving side...

I set message output to level 2 (verbose) and received the output shown below. Basically VLC holds up while outputting:

"access_mms warning: cannot fill buffer"
"access_mms error: no data received"

and then VLC decides to change how it is communicating with the server and video data transfer and display begins. In my application I cannot wait for 1 minute and hope it works.... Does anyone know how to address this or if there is a version that has?

Thx,

Steve.

Did you test with VLC 2.0.0 nightly builds?
http://nightlies.videolan.org/build/win32/?C=M;O=D branches are 2.0.0

Thx for the suggestion - just tried it but no luck. I believe I will try a few older version because it did seem to work at some point, just havent always been careful about which version I was using. That could get me to the right ver of VLC or LibAccess_Mms.dll plugin. Certainly appears this is a bug and if so surprised it has hung around so long... maybe Windows is not used as much as some other platforms or perhaps mms is not used that much, but would be a bit surprised on both counts. In any case, worst case I can patch and recompile.

Thx.
