  1. Hi,

    The Ultra Video Group has posted some new test videos that I would like to use for my Ice Lake QSV tests, the problem is that they are in YUV RAW format and I can't use them in Linux, none of the video players or video editors will play them.

    I tried converting them to Y4M using ffmpeg but even though the conversion seems to go fine and media info seems to show them as proper Y4M files, when I try to open them with any editor they won't open and when I try to play them back with any player, like smplayer, vlc or totem, all i see if a green garbled mess with lines all over the pace, basically a corrupt picture.

    Below is the link, I'm talking about the samples that begin with City Alley and have the following characteristics:

    Original Footage:
    Resolution: 4096 x 2160 pixels
    Frame Rate: 50 fps (progressive)
    Subsampling: 4:4:4
    Bit depth: 16 bit
    Data format: RAW

  2. Maybe you entered the wrong resolution or pixel format?

    Original recording was 16bit 4:4:4, 4096 x 2160 (4K), linear RAW, but the provided format is 10bit 4:2:0, 3840x2160 (UHD), YUV

    ffmpeg -r 50 -s 3840x2160 -pix_fmt yuv420p10le -i input.yuv -strict -1 output.y4m
