这是个交错的视频。你可以测下不同的反交错模式。看下那个的效果更好。 现在默认是1 你可以改成其他的值。 Picker("yadif Mode", selection: $yadifMode) { Text("yadif").tag(0) Text("yadif_2x").tag(1) Text("yadif_spatial_skip").tag(2) Text("yadif_2x_spatial_skip").tag(3) }

@kingslay @Kimentanm the issue here is not about de-interlace (yadif) filters the satellite signal of this stream is low, out of 50 frames, only 8 to 23 frames are displayed and that's why you see the mosaics.

I don't know if this artefacts issue is solved with it, but MPV uses the -crf filter in ffmpeg (https://github.com/search?q=repo%3Ampv-player%2Fmpv%20crf&type=code)

here is a screenshot using mpv

and using VLC (however if the display FPS is too low, you can see only 1 full clear frame; so the image freezes but you still hear the sound of the stream)

Sometimes I have this issue when I play 4K (50 fps H265) live streams. the green artefacts does not appear when I play the recording of the same content
