8168 Video Input Capture: Is the embedded sync supposed to be on both the Luma and Chroma channels?

Hello,

I understand that, currently, video input capture requires the use of embedded syncs.

QUESTION: Are the embedded syncs expected to be on both the Luma and Chroma channels?

While working with our video decoder chip on our custom boards we noticed that we'd configured it to

insert the SAV/EAV codes on all the channels and not just the Luma channel. Things work

fine while configured that way. We then attempted to limit it to just the Luma channel

and it stopped working.

We'll double check our configuration bits setup to be sure but I don't think I've seen any

mention of which channel the 8168 is monitoring for the sync. Is it both perhaps?

Thanks.

I realize this is an old post, but I just wanted to throw out that we experience this as well. With the 16-bit inputs on 8168, it does seem to require the sync be received on both bytes of the interface. The TI documentation says it is looking for it on the Y channel.

Hi,

Sync is required on any one of the two channels. This is selectable in hardware.

Hardik,

Thanks for the clarification. Is the option for which channel it is looking for sync configurable from the A8 side? Or is it only available in the M3 firmware?

Thanks,

Ryan

Hi,

I think you are using openmax VFCC component. So M3 side driver exposes this parameter to OpenMax. I am not sure whether this parameter is exposed through VFCC. They may be configuring this to M3 driver without getting exposed. I am not sure on this part. I will forward your query to EZSDK team. Are you trying to add your own decoder instead of TVP7002?

Hi Hardik,

You are correct, we are using the openmax VFCC component to capture video from our own FPGA source. For our application, we want to have 16-bit input on VIP1, and two 8 bit inputs on VIP2. We find only some of the input options seem to work:

- VIP1_PORTA, 16-bit 4:2:2 YUV, embedded syncs - Works

- VIP2_PORTA, 16-bit 4:2:2 YUV, embedded syncs - Works

- VIP1_PORTA, 08-bit 4:2:2 YUV, embedded syncs - Works

- VIP1_PORTB, 08-bit, 4:2:2 YUV, embedded syncs - Never receives any buffers

- VIP2_PORTA, 08-bit, 4:2:2 YUV, embedded syncs - Never receives any buffers

- VIP2_PORTB, 08-bit, 4:2:2 YUV, embedded syncs - Never receives any buffers

Is it possible the sync selection setting you mention is not being set correctly in VFCC component???

Thanks,

Ryan

Hi,

I am not sure whether all parameters are exposed by VFCC. Can you send me the dump of 100 registers for non working case. VIP0 address is 0x48105500 and VIP1 address is 0x48105A00. Please make sure that you add details to register dump, what is VIP configured for.

Hardik,

I have collected the register dump for 3 of the cases:

- VIP1_PORTA, 08-bit 4:2:2 YUV, embedded syncs - Works

Fullscreen 6710.VIP1_PORTA_08bit.txt Download

THIS IS For 8-bit, 4:2:2 YUV /w embedded syncs into VIP1_portA.
*** This one does work to capture frames!!! ***


After reset: VIP1 register dump:

*** SO, it waits indefinitely and never receives frames ***

For all of these, I have TVP5151 NTSC decoder providing BT.656 stream which we simply copy to all 4 8-bit VIP ports. So they all have the same inputs. I also included register dumps with VPSS started before enabling the data stream, and then while it is receiving video separately.

Please let me know if there is other information I can provide to help. It would be great to know if the VIP is actually getting configured properly.

Thanks,

Ryan

Hi,

Sorry for delayed response.

I will use terminology as VIP0 and VIP1 in that case it will match your terminology as VIP1 and VIP2.

Ryan Miller said:
VIP1_PORTB, 08-bit, 4:2:2 YUV, embedded syncs - Never receives any buffers

This port is receiving data. Status register says 720X244 received.

Ryan Miller said:
VIP2_PORTA, 08-bit, 4:2:2 YUV, embedded syncs - Never receives any buffers

This is not receiving any data.

In all configuration VIP is set correctly. So can you try following things. Make sure that your decoder if configured properly. Always start capture on /dev/video0 and then try capturing on other ports.

Hardik Shah

Hi Ryan,

I am trying to capture 8-bit bt.656 embedded sync using OMX App on DM8148 custom board using EZSDK 5.04 . We have got a Analog Devices video decoder providing video data in bt.656 format embedded sync on VIP1 PORTB .

I am trying to do capture on VIP1 PORTB ,I see that my OMX app hangs and VFCC is not able to capture frames . My OMX app has got only Capture component ,the app captures bt.656 data in YCbYcr format and stores into a file in YUV420sp format .

I see that you are able to capture 8-bit bt.656 embedded sync on VIP1 PORTB ,Can you tell us how did you solve the problem ?

Thanks.

Siva .
