Nvidia 하드웨어 H.264 디코더(Gstreamer가 포함된 nvdec)가 충돌합니다.

Question

Nvidia V100 GPU 카드를 제공하는 Azure 가상 머신 Nc6s_v3을 만들었습니다. 여기 지침에 따라 드라이버를 설정했습니다.https://docs.microsoft.com/en-us/azure/virtual-machines/linux/n-series-driver-setup.

nvidia-smi드라이버가 성공적으로 설정되었으며 도구 에 대한 적절한 출력을 볼 수 있습니다 .

Video_Codec_SDK_9.0.20을 성공적으로 컴파일했으며 샘플 애플리케이션을 실행할 수 있습니다.

Nvidia hw 인코더/디코드 지원을 활성화하여 Gstreamer 코드베이스를 컴파일했습니다. 인코더 플러그인이 nvh264enc제대로 작동하고 있습니다. 하지만 다음 스택 추적에서 디코더 플러그인(nvdec)에 충돌이 발생하는 것을 확인했습니다.

nvdec 오류:

여기에 도움을 주시면 대단히 감사하겠습니다.
