how can i use ipipe enging to resize a bmp file

Dan,

Which device are you using?

I want to use dm355 device to display a bmp file not no the osd but on the /dev/fb/3 in the format of YUV

because I want to  shorten the size of the bmp file.

Dan,

You'd need first convert the RGB data in the BMP file into YCbCr 422 before it can be sent to Resizer for resizing. The Resizer on DM355 only takes YCbCr 422 data. However, the resizer on either DM644x or DM36x can support input data in a single plane. so if you use those devices, you can pass the data through resizer 3 times, first R, then G & B.
