Hi CP,

I would like to continue the discussion on Mixer.

Mixer core stopped for unknown reason after I config the Input Control to enable.

This time the source of mixer input 0 coming from frame buffer and input of frame buffer is PTG.

output of mixer connect to a chroma resampler then CVO.

Mixer was configured with YCbCr 422 with Alpha Blending Enable, banckground is uniform.

When I set mixer to consume mode, the ready signal is always fine.

But when I switched to Enable, it stopped.

I attached the compressed stp file for your check.

As you can see, mixer received control packet at time 0 as 1920x1080p.

As soon as mixer received video packet at time 144 with 2 valid pixels.

Then ready signal switch to low.

Although the ready signal for CRS and CVO are always fine.

Any idea why this happened?

Regards,

Johnson
