WMV imput filter v1.4 + Virtual Dub 1.7.7 problems
WMV audio decode fail

Using the WMV plugin from there: http://fcchandler.home.comcast.net/~fcchan.../WMV/index.html
Into the latest stable VirtualDum v1.7.7 build 28312 from there: http://virtualdub.sourceforge.net/

VirtualDub says:
Quote
No audio decompressor could be found to decompress the source audio format.
(source format tag: 0161)


If the cursed VirtualDub could actually allow me to save the audio stream, like the VDub Mod does (but he did not allow importing WMV, damn M$!), I would gladly decode and re-encode it externally, but... what now? FFD audio decode? I tried, no help. VDub seems can use only some special filters...

The audio identification - beside the tag 0161 - GSpot says "Audio Codec..: 0x0161 (WMA v2)
Audio Bitrate: 191kbps 2ch VBR 48000Hz"
Windows Media Audio 9.2 - now where to get the decompressor for this WMA v2 format for Virtual Dub?

Anyone know? Please, help!

i would try mplayer to dump audio to pcm,

mplayer -ao pcm:file=out.wav -vo null -vc dummy in.wmv

---

other option to get the file into vdub is via avisynth;

Code: [Select]
directshowsource("in.wmv")

Another way is FFmpeg:
ffmpeg.exe -i x.wma -vn -f wav x.wav

However I lookign for a way how to make things work w/o troubles in VirtualDub, not for such problematic experiments...

Ok im a real beginner but i seem not to be able to decode WMA v2 with Virtualdub. The WMA plugin fixed the video playability just fine but the audio decoding won't work. What should i enable in FFdshow to make it work?
