If OMTB is:
omx setp 0 nf OMX_TI_IndexConfigAlgEnable bAlgBypass enable
omx setp 0 nf OMX_TI_IndexConfigAlgEnable nChId 0
omx api setconfig nf 0 0 0 OMX_TI_IndexConfigAlgEnableT
This is just use the bypass channel(422P to 420T), and not execute NF，is right?
If I want to execute 422P-NF-420T, how should I set?
Thanks.
Hi, Vimal, can you help me?
there is a gray rectangle in the bottom of screen.
why the display is no normal ?
