我创建了一个 Azure 虚拟机 Nc6s_v3，它提供了 Nvidia V100 GPU 卡。我按照此处的说明设置了驱动程序https://docs.microsoft.com/en-us/azure/virtual-machines/linux/n-series-driver-setup。
驱动程序已成功设置，我能够看到nvidia-smi工具的正确输出。
我已成功编译 Video_Codec_SDK_9.0.20 并能够运行示例应用程序。
我通过启用 Nvidia 硬件编码器/解码支持编译了 Gstreamer 代码库。编码器插件nvh264enc运行良好。但我看到解码器插件 (nvdec) 崩溃，并出现以下堆栈跟踪。
nvdec 错误：
