Off site video processing

Reading Alex's blog, http://www.boonex.com/n/dolphin-u-videos-transcoding, has my curiosity up.

Obviously this is for D U / D 8; or is it an up coming feature to all versions for video conversion/transcoding?

Remote video transcoding

Video conversion can be performed on separate server or multiple servers, to do it:

• install dolphin on separate server(s), but connect to the same DB which your main site is using
• enable 'Remote video transcoding' option (when it is enabled it takes a little longer to convert videos)
• add the following code to the begining of inc/header.inc.php file on the main site, where your actual site in installed: php define('BX_TRANSCODER_PROCESS_COMPLETED', ''); 
• if you don't want your main site to convert videos, so all conversion will be performed on the separate server, then add the following code to the begining ofinc/header.inc.php file on the main site: php define('BX_TRANSCODER_NO_TRANSCODING', ''); 
• all servers must have different host name
• only main server must be used as site, additional sites are just for video conversion, don't perform any action on these sites

if you are running a cluster of servers for dolphin, why you need different host names?

Forgive me for asking but what is the use of this? Plus its slower?

 The video takes longer to process but it doesn't bog down your site while it's doing it. Also if you have a shared hosting account and you modify Dolphin to process several videos at once it will put you over your resource limit. I'm guessing people will setup "video hosting" much like they have RMS hosting now and offer it as a separate service. This is all speculation..

Only one is used.

I'm hoping Alex can explain the process a bit more.

Yes Scott; it's in relation to the processing load put on the server while encoding videos, especially when the conversion settings are at the max in the flash settings.
