Can anyone recommend an HTML5 video player and/or HTML5 chatroom?
 

I want to convert my flash video player to html, but the software I was looking at charges a yearly fee.
Can anyone recommend a video player that is only a 1 time cost?
I'm also looking for an html 5 chat room if anyone knows a good one.
thanks

are your files in .flv or .mp4? if in .flv you will need to reconvert all videos. but if in .mp4 already, you can use videojs, or mediaelement, or a custom one like jw player with a custom skin.

Use HTML5 video tag.

If your video file in FLV format you can convert them into WebM or MP4 and use HTML5 video tag to play video
Details about <video> tag format could be found here: http://www.w3schools.com/html/html5_video.asp

And you can use free ffmpeg utility to convert all your video files in a batch. Here is example command line to convert flv into mp4:

ffmpeg -i input.flv -qscale 0 -ar 22050 -vcodec libx264 output.mp4

I can recommend even a free one. It's name is KVS Player. You can download a WordPress plugin for it here: http://wordpress.org/plugins/kvs-flv-player/

free

Does this plugin work with the latest Wordpress 3.9 update?

Course yes it does.
