Upscaling PAL to FullHD

Hello There!

I'm trying to upscale the PAL (720x576@50i) signal to a progressive FullHD (1920x1080) at same fps rate, while cutting equal parts from the top and the bottom of the source picture, to gain the correct "picture aspect ratio".  

My parameters look quite right for me, but i get "MFX_ERR_UNDEFINED_BEHAVIOR" error on the "MFXVideoSession::SyncOperation" call.

What i'm doing wrong? Thanks in advance!

"Intel API Implementation: MFX_IMPL_SOFTWARE Version: 1.13"

"-------VPP Parameter-------"

I solved the Problem by myself. The configurtation of input paramter was the issue:

"Width: 720"
"Height: 576"
"CropX: 0"
"CropY: 85"
"CropW: 720"
"CropH: 405"

405+2*85=575 and not 576 as supposed.

"CropH" should be changed to 406.

Nevertheless i would expect "MFX_ERR_INVALID_VIDEO_PARAM" as error.

 

regards,

Max
