    I have an .avi file with 2 audio streams that I'm trying to re-encode with AutoGK (the aspect ratio is off). When I start the job though, AutoGK gives the "Unsupported audio type" message and stops.

    The 2 audio streams are list in the Audio track window as:
    192 Kbps AC3 1ch
    130 Kbps MPEG-1/2L3 -- this is the problem one it's stalling on

    Media info on the 2 audio streams:

    Audio #1
    ID : 1
    Format : AC-3
    Format/Info : Audio Coding 3
    Codec ID : 2000
    Duration : 1h 26mn
    Bit rate mode : Constant
    Bit rate : 192 Kbps
    Channel(s) : 1 channel
    Channel positions : C
    Sampling rate : 48.0 KHz
    Video delay : 16ms
    Stream size : 119 MiB (8%)
    Alignment : Split accross interleaves
    Interleave, duration : 42 ms (1.00 video frame)
    Interleave, preload duration : 500 ms

    Audio #2
    ID : 2
    Format : MPEG Audio
    Format version : Version 1
    Format profile : Layer 3
    Codec ID : 55
    Codec ID/Hint : MP3
    Duration : 1h 26mn
    Bit rate mode : Variable
    Bit rate : 130 Kbps
    Nominal bit rate : 128 Kbps
    Channel(s) : 2 channels
    Sampling rate : 48.0 KHz
    Resolution : 16 bits
    Video delay : 3s 768ms
    Stream size : 80.6 MiB (5%)
    Alignment : Split accross interleaves
    Interleave, duration : 24 ms (0.58 video frame)
    Interleave, preload duration : 1416 ms
    Writing library : LAME3.90.
    Encoding settings : -m j -V 4 -q 2 -lowpass 17.6 --abr 128

    I have both of those codecs installed and use them often, and even updated them today, but I'm still getting "Unsupported audio type".

    What am I missing or doing wrong? I don't see anything out of the ordinary in the 2nd audio stream. I can process the audio stream with either GoldWave and Audacity, so I definitely have the proper codecs installed.

    If it's just the display AR that's off, perhaps MPEG4 Modifier could be used to correct that.

    If you want to keep both audio, you can demux them from the AVI and load the silent avi into AGK - then when that's finished, mux them back in with the likes of AviMux GUI.

    Yes, it's mostly AR being off that bugs me. The commentary audio track is out of sync a bit also, but since it cuts to very little movie dialogue between the comments, I wasn't going to worry about that.

    Thanks, I'll give that a try since I still can't seem to find a way to stop AutoGK from choking on that one audio stream.
