前言

鉴于 NV / Intel 的视频编解码能力信息较为分散，这里在其官网找到了两个适合的页面以供参考。

NVIDIA：NVIDIA 视频编解码器 SDK
Intel：Encode and Decode Capabilities for 7th Generation Intel® Core™ Processors and Newer

下面是从这些页面中复制的表格，以防后续页面失效。注意以下内容截止至2024年10月19日，更新的内容请在上方连接官网查看。
如果遇到标识支持而无法使用的情况，请先检查显卡驱动程序是否为最新。（例如Intel Iris Xe Graphics，Surface Pro 7+自带的旧驱动无法解码HEVC 4:4:4而新驱动可以）

Notes:

1 Stereoscopic 3D (S3D) supported on native HDMI 1.4 or HDMI 2.0 ports. S3D is not supported if LSPCON is used.

2 HEVC encode supports Low Delay B-frame (LDB) and Random Access Hierarchical B-frame (HB). P-frame is not supported.

3 Encode supported only on Linux

For all processor graphics listed here, there is no limitation on the number of concurrent sessions to transcode.
