[Libav-user] How can i get just basic info from an input video file by ffmpeg?

[Amir Rouhi-Rmit]

I found dump_format() function (not av_dump_format() ) among ffmpeg source
codes :  dump_format(ic, 0, is->filename, 0);
but i would be pleased if you let me know how can i find a tutorial which
shows how can i use the function ? and which header should be included?

BTW i need to extract raw pictures from any video as input which i can
achieve this by  the below command :

*ffmpeg -i input.avi -r 1 –f image2 –vcodec rawvideo* *-pix_fmt
yuvj420pImg-%03d.yuv
*
can you advice how can i achieve this in my c program? (I know that i can
run the command by popen() or sytem(), but i think there are some functions
that can do this for me too)
