[MPlayer-users] Audio Codec Support Request - with ftp'd files and regedit info for Sharp G.726

[Dan Hugo]

The source device is the Panasonic e-Wear SV-AV20/30 tiny camera.

Makes asf mpeg4 files.  Video is decoded fine thus far (the camera is
not high-performance so there are dropped frames and occasional
weirdness).  Audio is not.

Audio is G.726.  
format is 0x45 (69)
clsid is 094d04a1-9bf0-4343-867d-6ff0c6b975d4
The friendly name was "Sharp G.726 Audio"
The driver filename is "scg726.acm"
Fourcc not located in registry (nothing resembling what was described on
the codec import page was to be found... I'm no regedit pro, though)

There was one other instance of a clsid associated with the file, which
is listed here just in case as 52003641-6800-11D2-9cf9-00c04fcb385a

Dropped it in and tried it just to check.  The audio is properly
identified (? the sample rate and channel count look right), but video
holds at the first frame, no audio plays, and 'q' bails out like
normal.:
