Bug: .ReadIDTagElementValue and .AudioProperties give wrong rating on WMA

[chrisjj]

e.g.

* with WM/SharedUserRating = 0, .ReadIDTagElementValue reports 2 and .AudioProperties reports 1

* with WM/SharedUserRating = 128 .ReadIDTagElementValue reports 10 and .AudioProperties reports 5

* with WM/SharedUserRating = 255, .ReadIDTagElementValue reports 10 and .AudioProperties reports 5


dbScripting.DLL 13.3.0.2

Demo vbscript


'' DMC Rating bug

filename= "tempratingset.wma"
r = 0
dMC.WriteIDTag filename,"Rating",r
WScript.StdOut.Write("Setting rating to "&r&vbCrLf)

For each e in Split(dMC.AudioProperties(filename) ,VbCr)
if Instr(e,"Rating :")<>0 then WScript.StdOut.Write(".AudioProps says: "&e&vbCrLf) ' for 0 reports 1!
next

For i = 0 To 10000
keyvalue = dMC.ReadIDTagElementValue(filename, i)
If Instr(keyvalue,"Rating:")<>0 then
WScript.StdOut.Write(".ReadIDTagElementValue says "&keyvalue&VbCrLf) '' for 0 reports 2!
exit For
end if
Next

Our tag reader has to map the tag values to a 0-10 range so they can go to other codecs, so the ratings are approximations for WMA.

Thanks. Is WM/SharedUserRating the only property not reported faithfully?

If anyone has any details about the extent of this function's false reporting of property values, please do say. Thanks.
