21 |
Reads a portable pixmap as input. Produces 3 raw files |
| |
|
22 |
basename.Y, basename.U and basename.V as output. These files |
| |
|
23 |
are the subsampled raw YUV representation of the input |
| |
|
24 |
pixmap, as required by the Stanford MPEG codec. The |
| |
|
25 |
subsampling is done by arithmetic mean of 4 pixels colors |
| |
|
26 |
into one. The YUV values are scaled according to CCIR.601, |
| |
|
27 |
as assumed by MPEG. |
