Multiple resizing (usiing continous mode) on DM355

Hi

Now we use  multiple resizing on single shot mode to make HD720P and QVGA.(Linux Kernel 2.6.32-rc2)

But we want to use continous mode to improve Caputre frame rate.

We referred to "capture_prev_rsz_onthe_fly_bayer.c" of PSP3.01.

However, it can do only 1 resize.

Do anyone know how to do multiple resize on continous mode ?

Thank you.

    Hi,

    In continuous mode operation, you can only get upto two resized outputs. If you need only HD720P and QVGA, you should be able to get these two resolutions in continuous mode, but any extra resolution is not possible. For extra resolutions, you would need single shot mode.

    Now, specifically for the driver, you should be able to switch on the second resizer by switching output2.en = 1 for continuous config.

    Hope this helps.

    Hi

    thank you for your answer.

    I understand to be able  to get these two resolutions.

    But I have one more question.

    When one resize is used, we can get 1 buffer by using "VIDIOC_DQBUF".

    How do we get buffer of two resolutions ?

    thank you
