What is rocDecode?
|
|
********************************************************************
|
|
|
|
AMD GPUs contain one or more media engines (VCNs) that provide fully accelerated, hardware-based
|
|
video decoding. Hardware decoders consume lower power than CPU-based decoders. Dedicated
|
|
hardware decoders offload decoding tasks from the CPU, boosting overall decoding throughput. With
|
|
proper power management, decoding on hardware decoders can lower the overall system power
|
|
consumption and improve decoding performance.
|
|
|
|
Using the rocDecode API, you can decode compressed video streams while keeping the resulting YUV
|
|
frames in video memory. With decoded frames in video memory, you can run video post-processing
|
|
using ROCm HIP, thereby avoiding unnecessary data copies via PCIe bus. You can post-process video
|
|
frames using scaling or color conversion and augmentation kernels (on a GPU or host) in a format for
|
|
GPU/CPU-accelerated inferencing and training.
|
|
|
|
In addition, you can use the rocDecode API to create multiple instances of video decoder based on the
|
|
number of available VCNs in a GPU device. By configuring the decoder for a device, all available
|
|
VCNs can be used seamlessly for decoding a batch of video streams in parallel.
