Hi,

I have ported the VLC-0.8.6a for TI Davinci platform. TI Davinci platform
has 4 Framebuffer device (2 for Video supporting YCbCr 4:2:2 (UYVY), 1 for
OSD supporting RGB and 1 for Attribute). I have added another FB module for
supporting video framebuffer of Davinci.

With this ported code, I am able to view the perfect video clip on OSD FB
but on video FB I can only see some colored pixel distributed across half
of the screen.

As per the log input chorma FMT is I420 and output chroma format is UYVY.

Help sought to resolve the problem.

regards/Amaresh
