  4. Extract hevc and view in a stream analyzer like Zond. (SEIs with payloadTypes 137 and 144)

    Or maybe you can give MediaInfo author your sample and ask him to improve.

    Can you be clearer? I'm a beginner in this field.

  6. Open a request for MediaInfo (you can cut e.g. first 5 seconds using mkvtoolnix):

    You're a beginner in this field yet you are asking details about HDR metadata?! Something doesn't jibe.

    Yes I am. I need to get the MaxFALL and MaxCLL of an HDR10 sequence.
    I downloaded many HDR sequences from http://4kmedia.org/ and tried to get these information using mediainfo as sneaker's comment above but I couldn't.
    Now I am wondering that my sequences are HDR10 or not because as far as I know, the HDR10 metadata must contain MaxFALL and MaxCLL.
    Do you have any suggestion?
