The former is relatively compatible, while the latter is a headache.
Examples are as follows:
& ltvideo width = " 602 px " height = " 345 px " controls = " controls " & gt； ?
& ltsource src = " public/video/test . MP4 " type = " video/MP4 " >& lt/source & gt； ?
& ltsource src = " public/video/test . ogg " type = " video/ogg " & gt； & lt/source & gt； ?
Your browser doesn't support video tags?
& lt/video & gt； ?
At present, the video element supports three video formats:?
Format IE Firefox Opera Chrome Safari?
Og No 3.5+ 10.5+ 5.0+ No?
MPEG 4 9.0+ No No 5.0+ 3.0+？
WebM No 4.0+ 10.6+ 6.0+ No？
Ogg = ogg file with Theora video coding and Vorbis audio coding?
MPEG4 = MPEG 4 file with H.264 video coding and AAC audio coding?
WebM = WebM file with VP8 video encoding and Vorbis audio encoding?
Note: the format must meet the above three details, such as MPEG 4, H.264 video and AAC audio.
