Fairly recently (though I forget how recently), MeGUI started complaining about a channel count mismatch when it came to encoding audio for my AVISynth files. The encoding still succeeds, but it would be better if it didn't complain. Here's a log from my most recent encoding.
What is your audio input file? Have you created GCCX Out of This World Reel 1.avs on your own? Please post the content.
This is the AVS file I was using. I created it in MeGUI, then edited it myself. The named AVI, FFindex, and WAV files were in the same directory as the AVS file. I acknowledge that it's a bit complex; I can try making a simpler one that gives the same error.
Okay, I've constructed a downright minimal test case AVS. Included are the AVS itself and the log. All I did was open the AVS in the 'Video Encoding -> AviSynth Script' field, which populated the video and audio encoding areas, then click 'AutoEncode', then click 'Queue', then click 'Start' on the 'Queue' tab.
Thanks, has been fixed in 2505
