I recently flashed my jetson TX2 with Jetpack 4.2. While going through this [url][https://jkjung-avt.github.io/opencv-on-nano/[/url]](https://jkjung-avt.github.io/opencv-on-nano/%5B/url%5D), The poster mentions that opencv does nor support gstreamer capabilities on nano, specifically he mentions no hardware .h264/.h265 support. Is this true for Jetson tx2 aswell? If i need gstreamer capabilities do i need to manually compile opencv?

I have the TX2 with JetPack 4.2 installed, and Gstreamer works perfectly. Indeed, you can find more information in the user guide : [https://developer.download.nvidia.com/embedded/L4T/r32\_Release\_v1.0/Docs/Accelerated\_GStreamer\_User\_Guide.pdf?rlEClx5rvFY0D3eXv-tNJTxWHjiaPie67y\_JUhxvxLdiQM5xnsGGWD6jKc4uAQ\_1c9eYSojgGMEg0Ugq6vCHTFucX6cIXuFu30CCwSYLIv9xSkK7JzqyQo5BHU\_-DxyUpvMJKa0rLHc6ALOTpxrSzDhzwStLJ5Ri3A6dqPUdV5Ubf7RvnLs](https://developer.download.nvidia.com/embedded/L4T/r32_Release_v1.0/Docs/Accelerated_GStreamer_User_Guide.pdf?rlEClx5rvFY0D3eXv-tNJTxWHjiaPie67y_JUhxvxLdiQM5xnsGGWD6jKc4uAQ_1c9eYSojgGMEg0Ugq6vCHTFucX6cIXuFu30CCwSYLIv9xSkK7JzqyQo5BHU_-DxyUpvMJKa0rLHc6ALOTpxrSzDhzwStLJ5Ri3A6dqPUdV5Ubf7RvnLs)

Moreover, be careful if you are going to manually install OpenCV. JetPack already comes with an optimized version of OpenCV for Jetson (OpenCV4Tegra)
