[LRUG] Rails: using send_file to send video to the browser

[javier ramirez]

Hi,

I'm assuming you are using X-SendFile to send the file?

If so, you should be able to install the h264 module on Nginx/Apache and 
the web server should take care of the pseudo streaming

Also, this kind of streaming works better when the file is properly 
encoded[2]

Cheers,

j
