c++ - Passing reference of parameter's (being itself a reference) target -

-

i have chained methods that:

purecommand hasher::nametopure(commandname& commandname) {     return this->commandhash.find(commandname).value(); } bytecommand hasher::nametobyte(commandname& commandname) {     return this->puretobyte(this->nametopure(commandname)); }

the 2nd method passing commandname wrong type 1st method needs reference, not object. i've tried this:

bytecommand hasher::nametobyte(commandname& commandname) {     return this->puretobyte(this->nametopure(*&commandname)); }

as stated here: how cast/convert pointer reference in c++ - because &commandname gives me pointer... it's passing object again. doing silly way? it's trivial...

there nothing wrong original code. reference can bind object.

(and in fact, no expression ever has reference type. expressions can lvalues, xvalues, or prvalues, , commandname here lvalue, lvalue reference can bind it.)

i have implement video collection website users of specific isp. site hosted on public web-server movies hosted on local isp server. user of isp + general visitors can see available movies; isp's users able play them. player on site point url of local machine ( http://192.x.x.x/movies/mymovie.mov ) private class (192.x.x.x) accessible isp user. question: possible phpmotion script? or need custom work. if possible, can please suggest available mods? phpmotion require modifications able handle this. uploading, conversion, thumbnail generation, , playback pretty static in phpmotion. really though, rather modding entire upload , conversion process, if created quick custom form add entries phpmotion database (maybe include thumbnail upload), tweaked playback paths, should go on phpmotion side of things. assume had videos in format player handle (such flv or mp4).

javascript - Using Windows Media Player as video fallback for video tag -

getting video play cross platform using example video.js bit of fuss. in days when video should embedded use embed windows media player, work out of box on windows. since it's today old ie on windows doesn't support video tag experimented using windows media player fallback, , work well. what wonder here is, why haven't else solution? have missed something? code small, there's no flash files, cross domain issues or need of server working. works. so before develop further , add custom control , subtitles support wonder say. the code looks this: <video id="myvideo" style="width:640px; height: 360px;" autoplay data-wimpsource="http://esd.volvocars.com/dc/cdn/video/birds-on-a-wire.mp4"> <source src="http://esd.volvocars.com/dc/cdn/video/birds-on-a-wire.mp4" type="video/mp4" /> <source src="http://esd.volvocars.com/dc/cdn/video/birds-on-a-wire.webm" type="video/webm" />
