## Region of interest (roi) files
|
||
|
|
A simple text file can be used with the `--roi` switch to setup regions of interest for encoding.
|
||
|
|
Header row of the file will tell how many regions the encoded frames are divided (columns, rows).
|
||
|
|
The header must be followed by a data row with number entries equal to columns * rows.
|
||
|
|
The data row will tell the encoder which delta QP value will be assigned to each region.
|
||
|
|
The included example file will split frames into four regions with the top regions having a delta QP of +5
