: @12hstudy <--假装是白色: I would have to disagree. MP4 is a format that is standardized by the MPEG-4 family. It's compatible on practically any device without any hacks or plugins. FLV doesn't defaultly support subtitles, menus, chaptering, H.264, or H.265. It's an old standard from the Adobe Flash player days. If you were going to use an Abobe format I would recommend using F4V because it actually has some compression with H.264.
