Subject: [PATCH] media: bcm2835-isp: fix bytes per line calculations
|
||
|
|
for some image formats
|
||
|
|
|
||
|
|
The bytes per line numbers calculated by get_bytesperline was not
|
||
|
|
matching the equivalent calculation being performed by the VideoCore
|
||
|
|
(mostly by the calculate_pitch function there), resulting in failures
|
||
|
|
to set the image format with some image width values. This patches up
|
||
|
|
the RGB24 and YUYV type formats to match the VideoCore calculation.
|
