Well, the plot thickens. I wrote a little program to demonstrate the
problem, but I discovered something unexpected. The only files that
exhibit this trouble are the Bruce Williams's podcasts.
If anybody else is interested in this, here are the details.
1. Create a new RB project.
2. Drag a MoviePlayer, a Timer, and a StaticText control into the Window.
3. For the MoviePlayer1.Open() event:
Dim f as FolderItem
Dim m as Movie
Dim o as OpenDialog
o = new OpenDialog
o.PromptText = "Please select an audio file"
f = o.ShowModal
if ( f <> nil ) then
m = f.OpenAsMovie
if ( m <> nil ) then
MoviePlayer1.Movie = m
// must do this after loading the movie to make the player
clickable (RB bug)
MoviePlayer1.Top = 10
MoviePlayer1.Left = 10
MoviePlayer1.Width = 220
MoviePlayer1.Height = 16
MoviePlayer1.Play()
MoviePlayer1.Position = 100000 // go to the end
end
end
4. For the Timer1.Action() event:
StaticText1.Text = Str( MoviePlayer1.Position\60 ) + _
":" + Format( MoviePlayer1.Position Mod 60, "00" )
5. Use iTunes to download a Bruce Williams podcast. iTunes will say
it's 53:00 in length. Do a Command-R to locate the mp3 file, then
open the file in QuickTime Player. QuickTimePlayer will also report
53:00 in length.
6. Launch the above RB program and select the Bruce Williams podcast
(located in ~Music/iTunes/iTunes Music/Podcats/Bruce Williams/").
The player will advance to the end of the file and the StaticText1
will show the player position (53:15). The durations don't match,
but they are the actual time the mp3 will take to play in the
respective player.
So, QuickTime Player and RB player treat Bruce Williams podcasts
differently. RB plays the files using a slower rate (43892
samples/second, instead of 44100).
For the record, I'm using RB 2005 Release 4.
