[FFmpeg-user] Converting .264 to .avi (audio is out of sync)

I installed the latest version and it didn't solve the synchronism problem.
I tried to convert a h264+wav to an avi file with these commands:

ffmpeg -i input.264 -i input.wav output.avi
ffmpeg -r 15- i input.264 -i input.wav output.avi

in both cases the audio is out of sync. But when I specify an input frame
rate (-r 15) the result is better.

Here is the log:
