No.

The first one switches off buffering to disk.

The second one switches fastcgi module to the unbuffered mode. In  
this mode all data read will be immediately delivered to a client.

See [Module ngx\_http\_fastcgi\_module](http://nginx.org/r/fastcgi_buffering) for details.

For video streaming which option will be the best according to you

I currently use fastcgi\_max\_temp\_file\_size 0

fastcgi\_connect\_timeout 60;
