我用我的 GoPro Hero 8 拍了一段视频。当我用 VLC 播放器播放时，音频没问题，但屏幕是黑的。我发现这可能是由 HEVC 引起的，所以我从这里下载了 FFMPEG：https://www.gyan.dev/ffmpeg/builds/
我尝试使用这个问题的答案：如何将 10 位 H.265 视频转换为 H.264 且不损失质量？
ffmpeg.exe -i ..\..\100GOPRO\GH010194.MP4 -c:v libx264 -crf 18 -c:a copy ..\..\100GOPRO\GH010194_x264.MP4
ffmpeg.exe -i ..\..\100GOPRO\GH010194.MP4 -c:v libx264 -crf 18 -vf format=yuv420p -c:a copy ..\..\100GOPRO\GH010194_x264_8bit.MP4
ffmpeg.exe -i ..\..\100GOPRO\GH010194.MP4 -c:v libx264 -crf 18 -vf format=yuv420p -c:a copy ..\..\100GOPRO\GH010194_x264_8bit.mkv
我没有收到任何错误消息，计算机运行了合理的时间，并且我得到了大小合理的输出文件。但是，当我播放它们时，它们仍然是黑色的。
我尝试对该视频进行 ffprobe，并收到以下输出：

我如何才能将此视频转换为我可以观看的内容？我需要 Windows 10 吗？
更新：
我可以在 Linux 机器上完美地播放它。（但也想在 Win7 上播放。）
