 Download media file here:

 .\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:
 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?
