**ERROR: Too many frame drops -exiting

[Ross]

The -f 2 indicates a non-standard xvcd, so there are no rules.
Though it should work, the error says the video (e0) cannot stream fast enough to keep up with the audio. You may start by reducing the sample rate of the audio from 48khz to 44.1khz.

how do i change the sampe rate? do i have to reencode or is there a program that will do it for me?

[Ross]

I heard SoundApp will do it.

Or in MediaPipe it should go something like: File Browser->Quicktime Audio Decoder->MP2 Encoder.

Otherwise, iTunes->mp3 Quicktime->wav MMT->mp2.

RNC

INFO: Vbv buffer size : 0 bytes

This is a strange value. I'm understanding that this is a ffmpeg encoded stream. This could lead to some explanation on the lagging problems encountered with ffmpeg-encoded XVCDs.

What happens if you use -f 4 ?
