If you look in drivers/video/ti81xx/vpss/capt.c in the capture_create() function, you'll see a switch() statement that determines which VIP and PORT to use for the input. For the input, you have vidoe0, video4, video5, vidoe6 . These equate to VIP0_PORTA…

I'm not very familiar with modifying kernel drivers and using modprobe, insmod, and so on so I dont know if i'm doing this right or not.
IMO, if you are unfamiliar with basic things like modprobe/insmod and so on, you'll have…
Andy,
There are a few SD capture solutions which are based on TI's video decoder (TVP4146/TVP5147) which can very easily be swapped to the TVP5150AM1 or TVP5151 if cost is your primary concern.
If you refer to the data sheet you will find that ITU656…
Other Parts Discussed in Thread: TVP7002 , TVP5151 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…
Other Parts Discussed in Thread: TVP5151 , TVP5150 Sorry for my not enough gstreamer knowledge (I'm improving it...).
tvp5151 works on my custom board and I can get video using this command:
gst-launch v4l2src ! 'video/x-raw-yuv, format=(fourcc…

Hi,
There is no change required in the sample application as it uses V4L2 interface. What you need to is to create TVP5150 driver (if already not available) based on sub-dev model and attach it to 8148 master driver..

Dear Larry,
In my thought, my circuit has a correct capacitor value. Two 27pF are adopted in current. 33pF was tested also, but still same problem occurred.
Using 27pF is more close to 14.31818MHz than using 33pF when i measured by a frequency…
Hello Manisha,
The reason for autoswitch is not working because the register 0/40 (28h) is setting to 02h. Please set it to 0h to enable autoswitch (please read it back to confirm it is 0). The default setting for this register is 0 so you can just…
Other Parts Discussed in Thread: TVP5146 Since it is hard to attach images on last post, I repost my question here.
The output signals of TVP5146 in my deisgn are fading away in sequence from MSB to LSB.
What is the possible reason for this?
Anything…
