使用preload =“ auto”来避免在同一页面上重复加载HTML视频-
<!DOCTYPE html> <html> <body> <video width = "350" height = "200" controls = "controls" preload = "auto"> <source src = "movie.mp4" type = "video/mp4" /> <source src = "movie.ogg" type = "video/ogg" /> Your browser does not support the video tag. </video> </body> </html>
