Recommend way to write module to do expensive job

[hungnv at opensource.com.vn]

Hello again, 

I tried to modify our lib to make write job more efficient. At this time current lib can do this: 




When user request a file, nginx will pass request to intermediate lib (after doing some check), then the libraries will do very expensive job, read the input, process the video. But during processing phase, it will write output which is the data that can be read by browser to temp buffer, and append to output buffer (which is ngx_buf_t). The problem is at current state, I just can send response to client when the output buffer was completely filled, which takes a lot of time. But if I can write output to socket just after intermediate library write to temp buffer, it will be much faster. 

Is there any way to do this?
