<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Hi all,<br>at them moment I am working with x264 and vlc. Actually, I intend to change fps to control the output bitrate (because when I encoded akiyo.yuv with different fps, the same QP, the output bitrate varied). I also found this parameter (fps) in ratecontrol.c. Where should I begin and what should I do?<br>Thanks in advanced.<br>Binh.<br></td></tr></table><br>
