미니로그 혹은 게시글에서 자동재생은 2가지 방법이 있음

첫번째 방법은

<iframe width="원하는 수" height="원하는 수" src="https://www.youtube.com/embed/(동영상 url맨 마지막 부분)?autoplay=1" frameborder="0" allowfullscreen></iframe>

괄호는 지우세요()말하는거임




2번째 방법은 기본적인 틀은

<embed width="xxx" height="xxx" src="http://www.youtube.com/v/(위에말한 부분)&autoplay=1&version=2&loop=1"; type="application/x-shockwave-flash" allowfullscreen="true"></embed>

<embed height="xxx" type="application/x-shockwave-flash" width="xxx" src="http://www.youtube.com/v/(위에 말한 부분)&autoplay=1&version=2&loop=1"; allowfullscreen="true"></embed>


src="http://www.youtube.com/v/(위에말한부분)&autoplay=1&version=2&loop=1";(이거 앞에는 width="xxx" 또는 height="xxx" 가 붙어야함)

                   ㅣ   이 두개가 순서 바뀌어도됨   

 type="application/x-shockwave-flash"


width="xxx"  height="xxx"  두개의 순서는 바뀌어도됨


공백같은거 신경써야하는지까지는 테스트 안해봤지만
신경쓰는게 좋을듯함
