FFmpeg调用hevc_nvenc时出现‘Failed to query nvenc max version’错误及段错误的解决求助
大家好，我在Linux环境下使用FFmpeg结合NVIDIA GPU加速（hevc_nvenc）编码视频时，碰到了Failed to query nvenc max version的错误，最后还触发了段错误（Segmentation fault）。我已经尝试安装了FFmpeg、NVIDIA GPU驱动和CUDA SDK，不使用GPU加速时FFmpeg运行完全正常，但一启用hevc_nvenc编码就会报错，想请教各位有没有相关的排查或解决经验，非常感谢！
我使用的FFmpeg命令
ffmpeg -ss 10:00 -i /www/wwwroot/pyffmpeg/videos/0/011.mp4 -t 20 -r 30 -b:v 4M -an -vcodec hevc_nvenc -y /www/wwwroot/pyffmpeg/videos/post/999.mp4
命令输出内容

已做的排查操作
- 已完成FFmpeg、NVIDIA GPU驱动及CUDA SDK的安装部署
- 验证过非GPU加速模式下，FFmpeg的视频处理功能完全正常
