For now, enter this command line: <br>./x264 <raw input> <resolution> --qp <qp number> --output <output filename><br><br>This will encode your raw input stream into H264 with the default parameters.
<br><br>If you want to fine-tune your encoding and choose what to enable and what not, you can see a list of supported command line options by entering the following command:<br>./x264 --longhelp<br><br>So, for example if your raw input is
input.yuv, your resolution is 720x576 and your output h264 encoded stream want to be encoded.264, you should write:<br><br>./x264 input.yuv 720x576 --qp 26 --output encoded.264<br><br><br><br><div><span class="gmail_quote">

Dear Loren, <br><br>I am newbie in x264, and have been spending my days surfing the net to look for ways to pass my raw video data to x264 in stream ( no need to open a file). Can you show me how to do that? including the parameters needed.
<br><br>Is it correct that FFMPEG can only decode? but not encode as well? Since I have built my FFMPEG to include x264 library. <br><br>Thank you.<br><br><br><b><i>Loren Merritt <<a href="mailto:lorenm@u.washington.edu" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
