I made a video with my GoPro Hero 8. When I play it with VLC player, the audio is OK but the screen is just black. I found that this may be caused by HEVC, so I downloaded FFMPEG from here: https://www.gyan.dev/ffmpeg/builds/
I tried to use the answer from this question: How do I convert 10-bit H.265 videos to H.264 without quality loss?
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
I did not get any error message, the computer was working for reasonable amount of time, and I got files of plausible size as output. However, when I play them, they are still black.
I tried ffprobe on this video, and received this output:

How can I convert this video to something I can view? Do I need Windows 10 for it?
Update:
I can play it on my Linux machine perfectly. (But would like to do so on Win7, too.)
