CpuFallbackStatus

class torchcodec.decoders.CpuFallbackStatus(status_known: bool = False)

Information about CPU fallback status.

This class tracks whether the decoder fell back to CPU decoding. Users should not instantiate this class directly; instead, access it via the VideoDecoder.cpu_fallback attribute.

Usage:

• Use str(cpu_fallback_status) or print(cpu_fallback_status) to see the cpu fallback status

• Use if cpu_fallback_status: to check if any fallback occurred

Examples using CpuFallbackStatus:

Accelerated video decoding on GPUs with CUDA and NVDEC

Accelerated video decoding on GPUs with CUDA and NVDEC

status_known: bool = False

Whether the fallback status has been determined. For the Beta CUDA backend (see set_cuda_backend()), this is always True immediately after decoder creation. For the FFmpeg CUDA backend, this becomes True after decoding the first frame.
