AM572x VIN4a V4L2 interface with TVP5158 analog video decoder

Other Parts Discussed in Thread: TVP5158, AM5728

Hi,

TI,there is a tvp5158 on the vin4a port of my am5728 board,and I use the kernel from origin/processor-sdk-linux-03.01.00 branch.I got a tvp5158 driver from p-ti-lsk-linux-4.4.y-next branch.The dts file configuration like that:

Now the problem is that I can not capture the video.When I run the test software,it will show me that:

It seems like the driver only go into the vip_irq  function (locate in drivers\media\platform\ti-vpe\vip.c) twice.What is the problem?

If it got the video, I think it will go into the vip_irq  function again and again.But it not!

What happens will the interrupt occur?

BR,

vefone

    Vefone,

    Please remove the pclk-sample = <0> line from your dts file and also share the v4l2 logs. You can enable v4l2 frameworks logs as follows before running your application - Here X in VideoX is your device number.

    Hi,

    change the NV12 to YUYV,then I got the video.

    yavta -c60 -p -F/home/root/5158.yuv --skip 0 -t 1/30 -f YUYV -s 720x480 /dev/video1

    With multiplexed source the NV12 output mode won't work. VIP can accept input source as YUV 422 interleaved or RGB24 format (RAW formats also accepted). VIP internally has scaler, color format conversion, up sampling and down-sampling processing blocks. These processing blocks buffers couple of lines of input captured image for filtering need to do on the fly processing. When VIP input source is multiplexed, these processing blocks (chroma down sampling in your specific case) cannot process on the fly multi-channel input source as they do not have mechanism to line buffer separate channels. Multiplexed captured data is demultiplexed by the Parser and then directly passed to VIP DMA engine named VPDMA for the data to be written to memory as separate channels.
