วิธีการ อัพโหลดอาจจะต้องเปลี่ยนHello Khun BM
I have received your feedback
and I would like to inform you about this error
because the video not support on Chrome/Safari
if you would like the video support all browser
you might be convert and upload 3 type of video to support all browser
so our programmer suggest the easy way that the video will support all browser
is upload on youtube and link to preview on your website
