Re: [Vnc2swf-users] MP3 problems in python

[<db...@br...>]

I'm guessing that my MP3 files are in the wrong format as I see examples
on the web from people successfully using the Python version of vnc2swf.
I'm using audacity and exporting in the two formats they support (ID3
version 1, ID3 version 2).

Can someone tell me how they are making their MP3 files? I see that I'm
not supposed to use "variable bitrate" but I don't know if I am, or how t=
o
prevent it.

Here's the output of an attempt at adding sound with ID3v2:

$ python edit.py -o test-audio.swf -a test-2.mp3 test.swf
Using pygame 1.6.2
Reading mp3 file: 'test-2.mp3'...
read: [73, 68, 51, 4] : 'ID3=04'
read: [0, 0, 0, 0] : ''
Traceback (most recent call last):
  File "edit.py", line 173, in ?
    if __name__ =3D=3D "__main__": main(sys.argv[1:])
  File "edit.py", line 126, in main
    info.reg_mp3blocks(fp)
  File "/home/dblank/Desktop/pyvnc2swf-0.6.4/movie.py", line 83, in
reg_mp3blocks
    MP3Reader(self.mp3).read_mp3file(fp, length, nsamples, seeksamples)
  File "/home/dblank/Desktop/pyvnc2swf-0.6.4/mp3.py", line 153, in
read_mp3file
    assert (h & 0xffe00000L) =3D=3D 0xffe00000L, '!Frame Sync: %r' % x
AssertionError: !Frame Sync: '\x00\x00\x00\x00

The version ID3v1 seems to have about 418 bytes of \x00 on the front,
which causes the same error above. mplayer plays both versions of my test
files fine.

Anyone have an idea what might be wrong?
