Dual capture from tvp514x/tvp7002

Hello,

Is it possible to do a dual capture and display (ie is two streams one from tvp7002 decoder and other from tvp514x simultaneously) and store/display on hdmi ?

(using the dm814x_hdvpss_v4l2.xem3). Any sample apps to do this ?

There is no demo in EZSDK for dual capture.

But some customers have archive it ().

Hello,

The current  v4l2 capture driver does not support dual capture.  You should make changes  to enable the second input port in the V4L2 capture driver.

Is/does TI provide a patch for it ?

You could try to make these changes. It is possible since Ridgerun succeed it.

Is it the same case with open max firmware(dm814x_hdvpss.xem3) too ?

The HDVPSS source code is only under NDA.

He is talking about using OpenMax (OMX), not v4l2. The question remains, is it possible to do it using OpenMax? Thank you.

Hello,

The OMX does not support dual capture.

The OMX does not include support for TVP514x.

Thank you Margarita.

Just to let you know, I've been able to instantiate 2 OMX modules of the VFCC to do dual capture. It doesn't seem to support one component with dual output but it works great with two instances. One is using OMX_VIDEO_CaptureHWPortVIP1_PORTA and the other one is using OMX_VIDEO_CaptureHWPortVIP2_PORTA.

Have a nice day.
