ffmpegX 0.0.9r authoring failure (VCD or SVCD)

[Mildew]

I've been trying to covert a couple of AVIs using the vcd ffmpeg or svcd ffmpeg presets. The conversion seems to go fine but then fails with a frame underrun error. In the output folder, there appears to be a complete mpeg file: it plays fine and the audio is in sync. However, ffmpegX fails to author them as cue/bin or svcd img files.

I also tried remuxing the elementary streams but it fails almost immediately with a "too many frame drops" error. I've tried various profiles, but none of them work.

Does anyone know why ffmpegX doesn't succeed in authoring the vcd or svcd files after converting them?

Here's the info on the two AVI files:
VIDEO: mpeg4, 624x352, 23.98 fps. AUDIO: mp3, 48000 Hz, stereo, 141 kb/s
VIDEO: mpeg4, 624x352, 23.98 fps. AUDIO: mp3, 48000 Hz, stereo, 108 kb/s

The info on the AVI files is not useful, please post the info on the mpeg files (open them and copy the information lines as you did for the AVI files).

As requested:

VIDEO: mpeg-2, size: 480x480, 23.976 fps, 2948 kbps. AUDIO: mp2, 44100Hz, 224 kbps.

VIDEO: mpeg-1, size: 352x240, 23.976 fps, 1150 kbps. AUDIO: mp2, 44100Hz, 224 kbps.

Looks normal. Try to remux m2v and mp2 for the first file using XSVCD profile. Same result?

Didn't work. Something is screwy here. Both AVIs are basically the same size (347 MB). The outputted SVCD mpeg2 file is 604.5 MB while the VCD mpeg1 is 747.5 MB. The VCD should be smaller. How did that happen? Is it because of the different audio bitrates?

I split the AVI and converted the first half. The conversion and authoring completed successfully. So perhaps there is is something wrong with AVI file. I'm going to try converting and authoring the second half.

It is difficult to determine without checking the actual files. Email me to major4@mac.com if you have any means to upload them somewhere. As a last resort advice without seeing the files, I can only suggest to use mpeg2enc to encode, which although slower, always leads to more compliant SVCD/VCDs due to its better ratecontrol system.

Okay, I'll try that after I've tried a couple more conversions. BTW, this is the error I get in the terminal window:

Major,

Have you had a chance to test that AVI file I was having problems with?

Sorry, I have been busy in development of 0.0.9s which is now almost completed. I will check your test file ASAP.
