#7951 closed defect (duplicate)

Decode error with skip_frame set and a specific file

Reported by: ocrosoft Owned by:
Priority: normal Component: undetermined
Version: unspecified Keywords:
Cc: Blocked By:
Blocking: Reproduced by developer: no
Analyzed by developer: no


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 "" 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?

What is this a duplicate of? I have this problem with ffplay, VLC and MPC with video encoded with nvenc (with -bf 0). But the file plays good in Potplayer and microsoft "Movies & tv".
