%description
Qualcomm Iris (VPU35, SM8750) hardware video acceleration backend for Linux via
VA-API and stateful V4L2 M2M. Provides hardware-accelerated decode and encode
entrypoints (H.264, HEVC Main, HEVC Main10, VP9) for Chromium, Firefox,
ffmpeg, and Sunshine streaming on Xiaomi Pad 8 Pro (piano).

%build
# 交付的驱动必须自带编码入口。2026-10-15 装过一个只声明 VLD 的后端，ffmpeg
# 的 h264_vaapi/hevc_vaapi 静默失效。入口在 backend.cpp 的
# vaQueryConfigEntrypoints 里声明，实现落在 encoder.cpp，后者用的是
# VAEncSliceParameterBufferType / VAEncPictureParameterBufferType 这些渲染参数
# 类型，不会出现 VAEntrypointEncSlice 字面量，所以两个文件各查各自的特征。
