Chromium 133启用Nvidia多格式视频硬件编码及报错排查求助

问题背景 #

• 编译了最新版Chromium 133，尝试启用Nvidia 3060/3090显卡的硬件视频编码功能
• 使用的启动参数：

./chrome --enable-features=AcceleratedVideoDecodeLinuxZeroCopyGL,AcceleratedVideoDecodeLinuxGL,VaapiIgnoreDriverChecks,VaapiOnNvidiaGPUs,AcceleratedVideoEncode

• 该参数取自文章《Chrome Flags' Latest 2024 Update, Web Browser Video Hardware Acceleration on Linux》
• 目前仅能启用H.264硬件编码，无法找到启用HEVC、VP8、VP9、AV1编码的方法
