 hi,
I have a problem when I encode the video with mpeg4 code.
I use this command:

ffmpeg-y-threads 8-i-croptop INPUT.MOV cropbottom 90-90-s QCIF-aspect 16:9-r
24-vcodec mpeg4-pass 1-b 224k-maxrate 704k-bufsize 1408k-g 24-an-deinterlace
OUTPUT.MP4 & &
/ ffmpeg-y-threads 8-i-croptop INPUT.MOV cropbottom 90-90-s QCIF-aspect 16:9
-r 24-vcodec mpeg4-pass 2-b 224k-maxrate 704k-bufsize 1408k-g 24-acodec
libfaac -ac 2-ar 44100-ab 32k-deinterlace OUTPUT.mp4

by using the command I get an error message like the following:
Error: bitrate too low for this video with these parameters.
error while opening codec for output stream # 0.0 - maybe incorrect
parameters Such as bit_rate, rate, width or height.

please help

thanks a lot
