Intersil TW6869 features

Reference: Intersil TW6869 bridge chip

The Intersil TW6869 is a highly integrated solution that supports multi-channel video and audio capture via PCIe x1 interface for PC DVR systems and video analytic applications. It contains high quality eight-channel NTSC/PAL/SECAM video decoders that convert the analog composite video signal to digital component YCbCr data.

  • Tested resolution: 720x480.
  • Tested format: NTFS.

Enable driver

The driver was developed for kernel 3.10.67 using NVIDIA kernel source l4t-r23.2.

1. Follow the instructions in Compiling Jetson_TX1/TX2 source code (Downloading the code) to get the kernel source code.

2. Once you have the source code, apply the following two patches if you haven't yet, for fixing kernel errors during compilation.

kernel_r7_asm.patch

logical_comparison.patch

3. Apply the driver patches:

  • PCI-Add-quirk-for-setting-valid-class-for-tw6869.patch
  • fix-unknown-ioctl-V.patch
  • add-tw6869-driver.patch

4. Follow the instructions in Compiling_Jetson_TX1/TX2_source_code (Build Kernel) for building the kernel, and then flash the image.

Make sure to enable TW6869 driver support 

make menuconfig

Enable Analog TV support 

-> Device Drivers
  -> Multimedia support (MEDIA_SUPPORT [=y])
    ->Analog TV support (MEDIA_ANALOG_TV_SUPPORT [=y])

Enable TW6869 module 

-> Device Drivers
  -> Multimedia support (MEDIA_SUPPORT [=y])
    -> Media PCI Adapters (MEDIA_PCI_SUPPORT [=y])
      -> TW6869 (VIDEO_TW6869 [=m])

Mount the kernel module

sudo modprobe videobuf2-dma-contig                                                          

sudo modprobe tw6869

Examples

v4l2 utils

v4l2 utils V4L2 Test Application can be used for testing the driver, according to the input video resolution: 

v4l2-ctl --device /dev/video0 --stream-mmap --stream-to=frame.raw --stream-count=1

Also Raw pixels can be used for visualizing the captured frame.

GStreamer

To capture a video use: 

gst-launch-1.0 v4l2src ! xvimagesink
