By default, mobiles will display only HTML5 and not flash.
HTML5 will support only the following file formats :
MP4 with H264 (H264 is a codec format. Please visit http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC for more information)
So in order to display videos both in PC and Mobile it is better to have a common format. That is the reason we have mentioned that we should post MP4 videos with H264 codec format (Also called as HD Videos).
So please use any video converter to convert videos to MP4 H264 format so that it can be played both on PCs and Mobiles. Our customers have been using handbrake and have been successful with it. Please understand that this is not a restriction from our side. It is just that HTML5 supports only these formats. iOS devices cannot play flash content and only HTML5 can be used. This is the reason we have this limitation.
Also please note that we have mentioned that the FLV video plugin supports MP3, MP4, M4V, M4A, MOV, Mp4v and F4V formats. Unfortunately this FLV Video plugin cannot be used on iOS devices and is applicable only for PCs. So please understand that there is no false information on our site. We have just mentioned that our FLV plugin will support the above formats and we have also mentioned that it supports HTML5.
