issues reencoding mp4 aac to xvid mp3 using ffmpeg

[vantur]

I get an error when I try to reencode using ffmpeg. I also am unable to properly encode only the sound... all this happens apart from an mp4 movie encoded with the codecs found on www.cccp.com

here is a sample error.

Mac OSX static build for ffmpegX
Seems that stream 0 comes from film source: 2997.00 (2997/1) -> 24.00 (24/1)
Input #0, mov,mp4,m4a,3gp,3g2, from '/Users/vantur/Movies/Anime/gashbell65.mp4':
Fri Feb 24 04:16:15 CST 2006
0:22:49.9, start: 0.000000, bitrate: 1426 kb/s
Stream #0.0, 24.00 fps: Video: h264, yuv420p, 640x480
Stream #0.1: Audio: aac, 48000 Hz, stereo
Could not find input stream #0.2

same error occurs when trying to encode only the audio track from the mp4 file. note the mp4 file is using h264 AVC
thanks for your help.

Set audio track = 0 instead of 1.

Set audio track = 0 instead of 1.

reason I put 1 is that if I tried doing 0 with mencode and I get video without sound. Thus why I have been selecting 1 which makes the sound come out.

I just tried now doing what you said and selecting ac3 as the output i get this..

Note that I am encoding only the sound track no movie. this also occurs with mp3 selected from the summary window and no video encode. so far mencoder functions with video for me seem to be the only ones which work coming from an h264 file.

also please note that as of now, I am unable to cancel teh process in the progress window. I can press the x button as much as I like and it still goes.

Thanks

Can you email me a short clip (by using yousendit.com), I will try to test.

I will certainly be glad tyo. UNfortunately I am unable to cut the video with the tools I have on osx. (quicktime cannot play this video natively) what I will do is this. I will upload the file to my streamload account and email the link to you.
The file is 232 megs in size and streamload permits the usage of a download accelerator.
