Copy of reference.zip

My customer is seeing green artifact on (top) when running the CCS based test application example that ships with H.264 encoder v1.14.03. This is using the default encoder configuration that comes with the encoder package. Attached is copy of reference clip. Is this issue pertains to incorrect configuration - UMV enabling/disabling, luma/chroma swapping? Would appreciate any pointers.

Thanks,

Prateek

H264VEncApp.cmd.txt

To supply further information, here is the testvecs.cfg file I used

0 /* X: Value "1" does Test Compliance and Value "0" dumps the Output */
..\..\Test\TestVecs\Config\Testparams.cfg /* Test Parameters File */
..\..\Test\TestVecs\Input\test.yuv /* Input File */
..\..\Test\TestVecs\Reference\reference.264 /* Output File */

And the Testparams.cfg file I used:

# Input File Format is as follows
# <ParameterName> = <ParameterValue> # Comment
#

##########################################################################################
# Parameters
##########################################################################################
ImageWidth     = 704       # Image width in Pels
ImageHeight    = 480       # Image height in Pels
FrameRate      = 30000     # Frame Rate per second*1000 (1-100)
Bitrate        = 3000000   # Bitrate(bps)
ChromaFormat   = 1         # 1 => XMI_YUV_420P, 4 => XMI_YUV_422ILE
IntraPeriod    = 30        # Period of I-Frames
FramesToEncode = 5         # Number of frames to be coded

I also attached the cmd file I used here.

By the way, I have tried to use BIOS 5.31 and 5.41, Code Generation Tools V6.08, all have the artifacts.

Thanks for help!
