== Hardware Accelerators Overview ==
Jetson Xavier NX has different hardware accelerator units that help take out the most performance of the system without generating an extra CPU load on the processing. This platform contains the following hardware accelerated units:
* 384-core NVIDIA Volta™ GPU with 48 Tensor Cores
* 2x NVDLA Engines (DL Accelerator)
* 7-Way VLIW Vision Processor (Vision Accelerator)
* ISP
* Compositor (VIC)
* Multimedia Complex: NV encoder, NV decoder, NV JPEG


GStreamer takes advantage of those hardware accelerated units and offers a series of elements that use those HW-accelerated units to perform the respective processing.

'''''Jetson Xavier NX HW-accelerated encoding supported formats:'''''
* H.265 (HEVC)
* H.264
* VP9
* '''''NOTE:''''' VP8 encoding is not supported with hardware acceleration
<br>
'''''Jetson Xavier NX HW-accelerated decoding supported formats:'''''
* H.265 (HEVC)
* H.264
* VP8
* VP9
* MPEG-4 
* MPEG-2
* VC-1
