ffplay - "not implemented"-warnings flood the terminal

Reported by: Djfe Owned by:

Description

Summary of the bug:
The apng files from this page (https://flif.info/animation.html) generate a (seemingly) endless output of

 In-stream tag=[0][0][0][0] (0x00000000) len=0 is not implemented. Update your FFmpeg version to the newest one from Git. If the problem still occurs, it means that your file has a feature which has not been implemented.
[apng @ 000001bc46816f80] If you want to help, upload a sample of this file to ftp://upload.ffmpeg.org/incoming/ and contact the ffmpeg-devel mailing list. (ffmpeg-devel@ffmpeg.org)

Or rather only the cut off apng files cause this (the ones in the bottom row on the page)

This only happens when I play them with ffplay. ffmpeg and ffprobe only output one warning (or error)

How to reproduce:

This bug report is only about the endless command line spam.
The warning is likely caused by the incomplete file (I guess) and therefore it's correct that it's shown; but it would be enough if it would be shown once.
