I'm putting h264 video to the FLV container:

# /usr/local/bin/mencoder -o /tmp/80056336515605765
/root/videotest/Crete_Faistas.avi -ovc x264 -x264encopts
bitrate=288:frameref=5:bframes=0:me=umh:partitions=all:trellis=1:qp_step=4:qcomp=0.7:direct_pred=auto:keyint=30:threads=auto
-vf scale=540:436,harddup -oac mp3lame -lavcopts acodec=mp3:abitrate=128
-srate 22050

It looks fine - no artifacts

When I copy it in a FLV container:

# ffmpeg -i /tmp/80056336515605765 -f flv -acodec copy -vcodec copy -sameq
/tmp/test.flv

This video have artifacts by playing from a position to next keyframe.

Can someone help me? Or point documentation?

P.S. I'm using VLC player and Flowplayer. The results are the same.
