muxing two mono files doesn't work

[Wilbert]

I'm trying to mux two mono files and compress it to mp2.

mux file:

D:\TestGuide\lisa_mono.wav
D:\TestGuide\lisa_mono.wav

The original mono wavs are both 03:04:920 (they are exactly the same). The resulting stream sounds crippled and is about twice as long as the original.

(It also happens if I choose PCM-WAV instead of MP2.)

try feeding a single mono wave and transcode it to stereo wave to see whether this is a "mux" problem or simply an unsupported wave.

Wilbert,

Please explain, latter this .mp2 file shoud play as separate audio1 audio 2, o as "stereo" audio?

My mistake. I'm very sorry. They were actually stereo files with one silent channel. I feel so stupid ... Btw, wavs are coming from a capture process (vdub -> save as wav).

Anyway, I tried to demux the wav into two channels:

But it only produces one wav file.

It's late now, I will check it with normal wavs tomorrow.
