    Default 4k downgraded to FHD on SONY KD-55A8F

    Hi,

    I just bought a SONY KD-55A8F and wanted to play a 4k movie with MEZZMO.

    MEZZMO needed to transcode but the outcome was note at all in 4k. I looked at the FFmpeg reports and noted that the 4k resolution was downgraded after the transcoding :

    Original file :

    Stream #0:0(eng): Video: hevc (Main 10), yuv420p10le(tv, bt2020nc/bt2020/smpte2084), 3840x1608 [SAR 1:1 DAR 160:67], 23.98 fps, 23.98 tbr, 1k tbn, 23.98 tbc (default)

    Transcoded file :

    Stream #0:0[0x100]: Video: h264 (High) ([27][0][0][0] / 0x001B), yuv420p(progressive), 1920x804 [SAR 1:1 DAR 160:67], 23.98 fps, 23.98 tbr, 90k tbn, 47.95 tbc

    I tried to put the resolution at the maximum in the device parameters but it did not change anything.

    I also noted that the most sony updated version is the "2015 model": I don't see any updated version (a 4k ? high resolution ?), is it normal ?

    Thanks to find the log in attachment. Thanks in advance for your support !
