    Few usefull video snippets.

    Grabbing from DV cam, autosplitting scenes :

    dvgrab -- autosplit -timestamp  –format=dv2 video

    Deinterlacing :

    ffmpeg -i in-dv.avi -deinterlace -vcodec huffyuv -pix_fmt yuv422p -target pal-dvd out.avi

    Flv encoding :

    ffmpeg -i input.avi -ar 22050 -ab 64 -aspect 4:3 -b 768k -pass 1 -f flv -s 640x480 -acodec mp3 output.flv

    then again with

    -pass 2

    .

    Another solution :

    mencoder out.avi -o out.flv -of lavf -oac mp3lame -lameopts abr:br=56 -ovc lavc -lavcopts vcodec=flv:vbitrate=500:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 -srate 22050 -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames
