ffmpeg视频缩略图大小

I'm generating thumbnails like so:

exec(ffmpeg -itsoffset -4  -i '.$path.' -vcodec mjpeg -vframes 1 -an -f rawvideo -s 300x300 '.$other_path);

Is it possible to not specify the exact size of output image and set it to 100%?

    You can simply remove the -s 300x300 option, and it will note resize.
