But this command creates file with size 0 bytes.

If you have a minute, can you please look at these 2 files:

http://www.roamearth.com/ff/test23.m4v
http://www.roamearth.com/ff/logo7.avi


By the way, I've tried to encode files separately with the same -demuxer option,
but result file test2.flv is still 0 bytes. The full output:

INCORRECT files in the presence of B frames. Moreover, due to bugs MPlayer
