    I am trying to demux a file I have recorded from Satellite HD channel. I have used DvbviwerPro to record. The final file can not be played in most players. The video can be seen using MPHC, but without audio. I have tried ProjectX, Super, avidemux, Yamb, some video converters (include commercial ones) and no success. The problem appears to be in the audio stream. Mediainfo shows audio as AAc. It's AAC HE indeed. But most players and converters read the audio as Mpeg, so they can not play it.
    I have upload a sample file.

    I have search google, foruns and found nothing that work.
    Any help will be appreciated. I would like to demux my recordings and mux back (mkv) to see using WDTV media player, or computer.
    Thanks in advance.

  3. It uses LATM/LOAS AAC audio ; not very many software can decode it properly presently

    Use DGAVCIndex to demux the audio, use winamp to convert to wav, then convert the wav to something else that your media player can play (e.g. AC3 or regular AAC). For that wav=> (something else) conversion there are many options eg. megui, behappy, foobar2k, etc..

    The other method is to set up a directshow filter graph using graphstudio and the medialooks aac decoder (monogram), then use avisynth and directshowsource() with .avs scripts to convert

    Then mux back into .m2ts using tsmuxer , or mkv using mkvtoolnix (although .mkv overhead is 5-7% smaller than transport stream, .mkv can have problems with interlaced avc)

    Note: Mplayer has added support for this audio now, so you can use SMPlayer on the PC to playback for example

    OK it works using DGAVCDec/winamp. Now I can use TSmuxer to mux it back.

    Thank you very much for your help and fast reply.
