    I just started using ffmpegX very recently. I encounter a problem when I try to convert Quicktime MOV files (mostly trailers and such) to AVI XviD, there is no sound when I try to play the MOV file in ffmpegX and no sound after the file is converted. Video plays and converts successfully, just no audio. I am able to successfully convert other files (like AVI to AVI XviD). Any suggestions?

  2. Try to disable "Normalize audio" and use "XviD ffmpeg".

    The "Normalize audio" check box is actually greyed out. I tried XviD ffmpeg, no go.

  4. Can you send me a link to download such trailer, so as I can test?

    Sure, try the Cars trailer here.

  6. Try audio track=1 and framerate=NTSC.

    Hi!

    I have a very simmilar problem, and jump therefore on this thread... I hope I may do so...

    I have a .mov file with sound (both in QT and in ffmpegx preview), but when I convert to MPEG4 (mencoder) or XVID (mencoder) there is no sound in the final file...

    Any solutions?
    (I prefer MPEG4 btw...)

  8. Try audio track=1.

    Nice! That worked really well with the Cars trailer. Thanks!

    I have a follow-up question though, I tried converting another trailer (Harry Potter & The Goblet of Fire), and it produced 2 files, an AVI video file without any audio and an empty (0KB) MP3 file. I tried changing audio to AAC and same thing happened, it produced an AVI video file and an empty AAC file.

    Anyway, will definitely be registering ffmpegX.

    I also am having problems with encoding from .mov to anything else. I even downloaded the trailer mentioned in the previous post and used the audio track settings and framerate as suggested but no joy.

    If I drag the resultant file into the source panel it says no audio!

    Any other things I can try?

    Thanks

    I just tried it with the latest ffmpegX version (0.0.9t r2), and no more problems! Even the Goblet of Fire trailer converted successfully (I used XviD mencoder), I didn't have to change the audio track to 1, the default 0 was fine. Great work!

    Hmm...I just checked and I'm using 0.0.9t (0.0.9t) released on the 27th August. What does the r2 signify? Is there another release?

    Thanks

  14. It is a bugfix release. By doing apple-I on the application icon you can see if it is r2 or not. If it is not, download it again from http://homepage.mac.com/major4/ffmpegX.dmg (no need to install again the binaries, just overwrite the application).

    Thanks for the rapid responses!

    Yes, I just checked and its definately r2

    What else could be causing this?

    Cheers
    Don

    PS

    This bit looks very suspect in the output log:

    MOV track #1: 228 chunks, 0 samples
    Audio bits: 16 chans: 2 rate: 44100
    Audio extra header: len=76 fcc=0x77617665
    MOV: Found unknown audio atom >Fourcc: U

    Although the trailer plays perfectly before encoding?

  16. Try to export the audio as WAV with Quicktime Player, and add the WAV file in "Add audio.." in the audio tab, or remux it to your silent AVI with the "Mux" tool (Mux as.. AVI).

    I just re-installed the binaries and that fixed the problems with the trailer!

    I've now tried to encode a H264 mov file which I made using Quicktime pro. The video is being encoded fine but the resultant .avi is without an audio track. I've tried changing the audio track in FF but no joy. Heres the 1st part of the output file:
