Hey guys
I got a fmp4 video which was generated by ffmpeg. And the video format is hevc.
When I play it with windows ver. VLC media player and seek to any frame, the picture is abnormal. If you continue playing for a while, the image will return to normal.
It seems that the seek operation landed on a non-key frame, due to the lack of reference frames during decoding. So, the resulting image is abnormal.
But it’s strange that VLC player on Mac do not have this issue.
My VLC player version of windows is 3.0.21 Vetinari. And here is the detail of this fMP4 video:
