vpi.Backend

class vpi.Backend

Set a backend (unit of processing) to run an algorithm.

All algorithms require a backend where it will be executed. There are two ways of setting the backend:

1. Define it as an argument to the algorithm call;

2. Define it via a with statement, where the backend is defined for all algorithms called within that with statement.

Enumeration values

vpi.Backend.CPU	Use the CPU for processing.
vpi.Backend.CUDA	Use the GPU for processing.
vpi.Backend.PVA	Use the PVA on Tegra for processing.
vpi.Backend.VIC	Use the VIC on Tegra for processing.
vpi.Backend.OFA	Use the OFA on Tegra for processing.
vpi.Backend.NVENC	Use the NvENC on Tegra for processing.
vpi.Backend.DEFAULT	Invalid backend, used when no backend is set.
vpi.Backend.AVAILABLE	List of backends available as an OR-based field.

Hint

Backends can also be submitted to bit-wise operations, e.g. vpi.Backend.NVENC & vpi.Backend.AVAILABLE, useful when querying if a particular backend is available.
