            avformat/mpegts: parse large PMTs with multiple tables
    

    
            In 9152c1e4955, the mpegts parser was taught how to parse
    
            PMT sections which contained multiple tables. That commit
    
            fixed parsing of PMT packets from some cable providers,

    pngdec : set correct range

    AV_PIX_FMT_GRAY8/16 are considered YUV formats, and the color_range is
    
not set - so the API user will have to assume limitted range. (Unless
    
the API user adds a special-case for the PNG decoder.)
    

    Just export the correct range - full range.
