Hi Sensor Test,
From your question: Is that means I can use MIPI CSI input 8 or 12 ways videos to TX2 at L4T R32.2.1?
If you want to get 8 or 12 outputs from a single input source, this could be possible by creating N number of OutputStreams for single input CaptureSession based on your requirement.
You can refer the documentation present in
For reference you can check multiStream sample provided in tegra_multimedia_api/argus/samples in which the single camera input source is used for concurrently capturing jpeg images as well as streaming using OpenGL renderer.
