WMV, sound missing at begin

[xerces8]

With almost all WMV files, the sound is mssing at the begin of the movie.

For about a second, I see the picture, but no sound. Then the sound comes and plays OK until the end. It is in sync with the picture. Only the first one or two seconds are missing.
This happens with almost every WMV file.

I have VLC 0.8.4.a on WinXPpro-SP2.

Is this a known issue ?
What can I do ?

I have experienced this from time to time with every type of file. It seems that when the file is not encoded properly (also depends on encoder vendor) or the file is cut to tight (not enough time to open correctly) is when this problem is manifested and it takes a moment for it to correct itself. I have not witnessed this problem specifically with WMV files.

Well, those files all play properly in WMP.
Especially with short videos, this is a serious problem, since half of the record is without sound.

VLC supports WMV is only under Windows and uses the Windows codecs, one of the few exceptions for VLC. Considering what you are suggesting (that the codec recognition is slow (somehow doubtful)) you could try a later version to see if your issue has been resolved. All Digital Video is lock to Audio and generally doesn't start until the codecs and converters open and it has lock. But all commercial product gives the benefit of the doubt by providing a moment of silence or Black Screen to provide lock before the video or audio starts.

I never suggested that codec recognition is slow.
I just stated, that the sound is missing at the begin of almost every WMV file.
You also stated, that it happens with other formats too.

I'll try a VLC beta as soon as I can.

You may not realize you did but you did!

In any event, the player time to open a codec is not relevant, what is relevant here is the codec time to open the converters and report it to the player and that you say WMP opens the file and plays without problem and in this case VLC is using the same codec. It is the codec that decides how and when to open the converters and lock the audio and video. However if the file is cut to close without allowing a moment for everything to gel and or lock, I have seen problems with almost every file type and almost every player even using the same codecs. The only resolve I know of, is during the editing and encoding process.
