{{{
.\ffplay.exe -skip_frame "bidir" -i "D:\video\LG Chess HDR.mp4"
}}}
When set "skip_frame" arg, and it's value >= noref, ffplay may display
some frames incorrect, like this:
[[Image(https://www.ocrosoft.com/wp-

Other player use ffmpeg (like mpv player), the permormance is worse than
ffplay, after display a "grey" frame, some mosaic remained(disappear about
1 seconds).
And more, the command line print this error message: " Could not find ref
with POC xxx"(xxx mis a number).
This reproduce rate is 100% for this file.
Another video "LG Cymatic Jazz HDR10.mp4" download from
"http://andytather.co.uk/panda/videogallerypage.aspx" too.
But other download from above page, it's not LG's video, ffplay and mpv
play it good. May LG* video has some encode error?
