TW6869 features
Reference: Intersil TW6869 bridge chip
The Intersil TW6869 is an HDMI 1.4 to MIPI CSI-2 1.01 bridge chip capable of handling video data up to 1080P at 60 fps. The Intersil TW6869 is a highly integrated solution that supports multi-channel video and audio capture via PCIe x1 interface for PC DVR system and video analytic application. It contains high quality eight channel NTSC/PAL/SECAM video decoders that convert 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 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_source_code (Build Kernel) for building the kernel, and then flash the image.
Make sure to enable TW6869 driver support
make menuconfig

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
