EZSDK 3.01 video4Linux saLoopback application with D1 resolution in TI814x EVM

Hi,

Looking at the saLoopback example, I can't see support for D1 resolutions (NTSC,PAL). When I set the component input to D1, the example fails to run.

Is this a limitation of the capture driver? Is so, how do we add support for D1 capture?

Also is D1 display supported through v4L driver?

Also running the example with 720p60 component source, gives me this error:
