convert H264 video to raw YUV format

问题:

Is it possible to create a raw YUV video from H264 encoded video using ffmpeg? I want to open the video with matlab and access Luma, Cb and Cr components frame by frame.

Yes you can, you just have to specific the pixel format. To get the whole list of the format:

ffmpeg -pix_fmts | grep -i pixel_format_name

For example if you want to save the 1st video track of an mp4 file as a yuv420p (p means planar) file:

ffmpeg -i video.mp4 -c:v rawvideo -pix_fmt yuv420p out.yuv
