Omap 4460 h.264 encoder supports 10-bit input?

Other Parts Discussed in Thread: 4460

Hello,

We are connecting Omap4460 to a 10-bit wide dynamic range camera sensor. The question is if the h.264 encoder of omap4460 supports 10-bit input 720P resolution or these extra bits are simply thrown away.

Thanks,

Hi,

What is the sensor type? Is it a RAW sensor or a SMART sensor? H264 encoder does not support 10-bit input, it supports only 8-bit NV12 format.

Hello,

It is Omnivision WDR sensor OV10633:

It has 18-bit combined raw, 10-bit seperated raw, or 8 or 10 bit YUV 422 format outputs supported.

The MIPI input of OMAP 4460 supports 10-bits. I hope H.264 HP or MP supports 10-bit inputs so that the extra bits of WDR input is not wasted.

Thanks.

I believe sensor output format you are talking about is 10 bit bayer, can you please confirm?

The Camera sensor has on chip ISP, and outputs 10-bit YUV 4:2:2, as I mentioned before.

Hi,

Like I mentioned earlier, H264 encoder supports only NV12; YUV420 8bit format. So the best option is to configure the sensor in YUV422 8 bit mode, do a color conversion in ISS, and feed it to H264 encoder.
