  • No support of SWF.
    My MPEG audio parser has difficulties to detect false MPEG Audio, because MPEG Audio "magic value" is only 12 bits
    I will put more tests about coherancy of value (bitrate 0 and so on...)

    I would like to differenciate them.

  • while "MPEG-4 Audio" is technically correct, i think it would be more helpfull for users if you would write "MPEG-4 Audio (AAC)" and maybe even "MPEG-4 Audio (HE-AAC)" too.
  • I will look at what I can do. Not sur to be able to always differenciate them.

  • this movie here (http://www.kollektiv-kaffeemaschine....erarbeitQT.mov) has exactly the same codecs, but this time "ima4" is detected as a second video track instead of the audio track.
  • I will download theses files

    Or : you can edit preferences (for "sheet" view, or HTML...), and add "%Codec%" (instead of "%Codec_String%)

  • I don't have files with a container but without streams, could you send me one?

Interested to have it.
