javascript - How mobile YouTube page autoplay videos on iOS? -


i'm trying understand after 2 days of digging code thought post issue here...

according apple's documentation, autoplaying videos on ios devices cannot done without user interaction first (e.g. tap on video). despite that, mobile youtube (m.youtube.com) able autoplay videos after loading page video.

does know how doing it?

ps. i've checked available js/html techniques of autoplaying videos on website on ios (e.g. iframe, fake click, triggering touch event on video, fetching video xhr).

i believe youtube.com single page app. when user clicks on video list view page not loading , javascript uses initial click, leads video page, click starts video. it's not autoplaying, it's trick.

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
