If i remember right, i had to change this method to get a generated file fr=
om a special db into the mediadb (when required):

    # ---------------------------------------------------------------------=
-----
    #  ZMSGlobals.FileFromData:
    # ---------------------------------------------------------------------=
-----
    def FileFromData( self, data, filename=3D'', content_type=3DNone, media=
dbStorable=3DFalse):

before:

    def FileFromData( self, data, filename=3D'', content_type=3DNone ):

otherwise each generated file from a onChangeObject is landing in the ZODB =
instead of a configured mediadb. If i remember right, with Images / Image b=
lobs this was working out of the box instead.

this works here so far for MP3s in a web player and in iTunes. If i remembe=
r right, i had to fiddle with the correct Headers a while. So may be this c=
ould bring you on a way it works for you (hope so)...

Cleaned out a bit from stuff not relevant here. Some of the headers are gon=
e to the frontend proxy, so this may be incomplete or lines are commented o=
ut. No guarantees so far!!!

request =3D container.REQUEST
RESPONSE =3D request.RESPONSE
session =3D context.REQUEST.SESSION

RESPONSE =3D  request.RESPONSE
counted =3D False

try:
  if context.getObjProperty('audiofile_playout',request):
     file=3Dcontext.getObjProperty('audiofile_playout',request)
  else:
     file=3Dcontext.getObjProperty('audiofile',request)

  #filetype=3Dfile.getContentType()
  filetype=3D"audio/mpeg"
  filename=3Dfile.getFilename()
  filesize=3Dfile.getDataSizeStr()
  fileurl=3Dfile.getHref(request)

  # rise in object request counters
  try:
     # count on the ad
     # -> remember last played/requested url
     context.countMP3Requested()

     # generates cookie / session if required
     #if not session.get('last_played_id'):
     #   session.set('last_played_id','no')

  return file.getData()

good luck,


Niels.
