Hi,

Can you comment on the <video> tag in these areas:
1) supported players
2) youtube videos
3) cross platform support - windows, linux, + IOS (specifically this one too) - what is the reality these days?
4) performance - what if have more than one video tag, or hide/show layers w/ video tags in them & pause the playing... is there still a performance problem?
+ noticed that running videos the performance of the screen is degraded - any tips on this? We'd like to show a video while animated data is being pushed to
screen real-time (websocket and webworkers..etc), yet there are only 5-10 of these types of updates. I'd like to pin-point where performance problems occur
and as such can you recommend any tools to identify?
5) does your book cover video tag and how to control video thru javascript?

Thanks,
Joel

Hi Joel

1) I'm not sure what you mean by this exactly, here's a list of browsers that support the video element, you don't need a separate player
2) YouTube has an HTML5 option
3) See 1
4) You'll have to be more specific here, I've not seen any performance issues myself but I probably haven't been trying to do the things you've been doing. Chrome has a load of developer tools built in for measuring performance, there's some nice tips in this presentation
5) Yes, but it concentrates on the basics

I imagine that by "player" he actually meant codec. To see what browsers support which codecs, click on the sub-features links at the above link.
