我使用 ffmpeg 为 Windows 构建吉安： 发布ffmpeg-5.0-完整版具有硬件支持。我需要从 USB 视频设备捕获视频，压缩视频并将其写入文件。我使用以下命令行：
ffmpeg -f dshow -i video="USB Video" -c:v h264_qsv m:\out21.mp4
我收到错误：
Error initializing an internal MFX session: unsupported (-3)
此错误发生在不同的系统上：
台式机，Windows 7，英特尔酷睿 i7-4770
平板电脑，Windows 10 企业版，英特尔赛扬 N3350E
附上报告台式机，Windows 7，英特尔酷睿 i7-4770

答案1
问题原因是未安装集成的 Intel 显卡。设备管理器中缺少设备“Intel HD Graphics”。
在 Windows 7 上我无法安装驱动程序，因为英特尔不提供此类操作系统和处理器配置的驱动程序。此外，还安装了独立显卡。
在 Windows 10 中，集成的 Intel 显卡被 Microsoft 设备所取代。安装驱动程序后，设备“Intel HD Graphics”出现，h264_qsv 开始工作。
