ffmpeg real-time encoding while file uploading by chunks

Now the process is:

1. File upload
2. Encode file with ffmpeg when file has been uploaded

Can be done at the same time?, obviusly yes, but I don’t know how.

The file upload process is by 8MB chunks stored in server, then, temporary I have videofile.ext.tmp that is growing up to final uploaded file.

I read about ffmpeg -stream_loop or -loop parameters, but I don’t know if the upload process is good for real-time encoding or how to manage it.

Any help will be appreciated.

EDITED: I tried this feature and works good when: Internet connection is faster than ffmpeg encode speed. When uploaded file is big enough.

I personally ruled out this procedure because the internet speed may change or cut out.

Answer

It depends on the file format. Some formats like ts,mkv,flv will work this way. Mp4 may or may not work depending on how the file was created.
