[Mp4-tech] ADPCM in mp4 container

[Satyanarayana.N]

yes you are right having audio or/and video in separate files is possible.
for further details refer MP4 file format document.
    any codec combination for audio and video should work together, provided
these two codecs are supported in standard and generated file is according
to file format standard.

  Hi,
  I would appreciate any reply regarding below questions:
  - Is the "url" box type actually supported by standard players (i.e. can I
  have video and audio in separate files: lets say an mp4 file contains the
  video data and also has an url pointing to another mp4 file which contains
  audio)?
  - Is it possible to have IMA-ADPCM compressed audio in an mp4 file? If
  possible, would a standard mp4 player -such as Apple Quicktime- play
  IMA-ADPCM audio with mpeg-4 video?
  Thanks in advance!
  Alptekin Temizel
