tvp5158 control question

Other Parts Discussed in Thread: TVP5158

Hi,

I am working on dm816x evm board + vs daughter card.

I want to dynamic change ntsc or pal mode on tvp5158.

Can I change it direct through command IOCTL_VPS_VIDEO_DECODER_SET_VIDEO_MODE at run time?

Or does any sequence need to be follow?

I am using RDK 01.08.00.15.

Thanks.

Jacson

    Hi,

    The IOCTL is supported in the video decoder driver, but currently we use the auto mode detection in the capture link. Actually, we can configure the capture link to NTSC or PAL from the user application during create time, assuming SYSTEM_USE_VIDEO_DECODER is set to false.

    As capture link does not support dynamic resolution change currently, we cannot change from NTSC to PAL or vice versa. We plan to add this feature going forward after Ver 2.0 of DVRRDK.
