  • avcodec/pngdec : improve handling of bad cICP range tags

    avcodec/pngdec : improve handling of bad cICP range tags

    FFmpeg doesn't support tv-range RGB throughout most of its pipeline, so
    
we should keep the warning. However, in case something does support it
    
we should at least keep it tagged properly. Additionally, the encoder
    
writes this tag if the space is tagged as such so this makes a round
    
trip work as it should.
    

    Also, PNG doesn't support nonzero matrices but we only warn and ignore
    
in that case, so we have no reason to error out for illegal cICP ranges
    
either (i.e. greater than 1).
