[x264-devel] Problem using ffmpeg with flags

[Stefan Klein]

hi!

It should be:

*ffmpeg -i INPUT -an -pass 1 -s 1024x576 -vcodec mpeg4 -b 2500k -flags 
aic -flags cbp -flags mv0 -flags mv4 -flags trell -mbd 2 -cmp 2 -subcmp 
2 -g 250 -maxrate 2.5M -bufsize 2M OUTPUT

but:
I would not use -y...
and:
this is not really a developer question, is it?!
