I search the <a href="http://opencv.willowgarage.com">http://opencv.willowgarage.com</a> for ffmpeg and just receive a limited usage of ffmpeg.<br>I have seen that ffmpeg has many functions and headers which we can use them by calling the functions if we have included the proper headers. I am looking for a documentation for functions and related header files. For example if i need the dimensions of a video file, how can i call some ffmpeg functions to do it? or how can i use a command line of ffmpeg like:<br>
fmpeg -i input.avi -r 1 –f image2 –vcodec rawvideo -pix_fmt yuvj420p Img-%03d.yuv
<br>in my c code lines?<br><br><div class="gmail_quote">On Thu, Jun 30, 2011 at 1:04 PM, Saurabh Gandhi <span dir="ltr"><<a href="mailto:saurabhg84@gmail.com">saurabhg84@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
