 * interface.

 * eid      - encoder id.
 * bsize    - buffer size (in bytes, will be padded if necessary).
 * cancelop - set to 1 to stop the operation and return 1 if it was sucessful.
 * pauseop  - set to 1 to pause the operation (till you set it back to 0).
 * (uses the same system in 'internal output')
 * trans    - transcoder settings (new!).
 *
 * use a thread to call this function, or just put this into a thread.
