What is FFMPEG? How can I use it for fomat conversion?

Question

How can I use it to convert yuv files to avi files? And back. I am currenlty working on a project that needs to process a yuv video into matlab. I only know how to load an avi file by using mmreader. Is there any other way to read yuv files in Matlab?

What is FFMPEG? Start with FFMPEG home page

The most common format is YUV4:2:0 planar 8-bit (YUV420p). For yuv to uncompressed avi conversion use command:

ffmpeg.exe -s 352x288  -vcodec rawvideo -f rawvideo -pix_fmt yuv420p -i
in.yuv -sameq out.avi

where framesize is set with -s 352x288

And for avi to yuv conversion use command:

ffmpeg -i in.avi -vcodec rawvideo -pix_fmt yuv420p -o out.yuv

Converts any input to 420 planar yuv.
