    hi, what is the description in the video info telling it is a x264 and x265 encoded video?

    for exemple i have a x264 video with this:
    Identifiant unique : 205749229756292421717401371892188771506 (0x9AC9DC3A252B9829AC1772B4F4F0F4B2)
    Nom complet : H:\temp\randomvideo.x264.mkv
    Format : Matroska
    Version du format : Version 4 / Version 2
    Taille du fichier : 461 Mio
    Durée : 1 h 31 min
    Débit global moyen : 702 kb/s
    Date d'encodage : UTC 2016-12-03 01:12:13
    Application utilisée : mkvmerge v8.3.0 ('Over the Horizon') 64bit
    Bibliothèque utilisée : libebml v1.3.1 + libmatroska v1.4.2

      your are checking the "general" part, and your file is not a "raw video" (only video). this is a container, containing several streams.

      check the "Video" part of the report, "Format" line for the format (AVC i.e. H264 or HEVC i.e. H265), "library" for the library name (x264 or x265).

    Hi,

    The video paramter InternetMediaType will give you video/H264 or video/H265.
    But perhaps it's not the only parameter that will give you the answer you expect.

    Or perhaps the video paramter CodecID/Hint ?

      The video paramter InternetMediaType will give you video/H264 or video/H265.

      No, because the file is not a H264 or H265 file, it is a Matroska file.
      the file contains a H264 or H265 stream, but it is not the file.

      Or perhaps the video paramter CodecID/Hint ?

      It is an hint about the format.
      Here, I understand "x264 and x265 encoded video" as the request to know the library used for encoding, not the format (which is H264 and H265, not x264 or x265 which are encoders)

        Sorry but I don't understand your answer.
        And what do you call a "H264 file" ?

        So, what is the right answer to Pierre's question ? ;-)

          And what do you call a "H264 file" ?

          A file containing only H264 content (no container, e.g. no AVI, no MOV, no TS, jsut a raw H264 stream).
          You don't do the difference between a container (AVI, MOV, TS...) format and a video format.

          InternetMediaType is about the format of the file, not about the content transported by the file (except in rare cases).
          MediaInfo does not provide InternetMediaType for each stream transported by the file, only the InternetMediaType of the file.

          Also there is a misunderstanding between x264 (an H264 encoder/decoder) and H264 (a video format).

          You didn't answer to Pierre. ;-)

          I did

            I still don't understand, but it doesn't matter. ;)

            Oups, I haven't seen you answered to Pierre. Really sorry. :(

            Thank you and have a good day
            Bye

    oh yes i can find h263(4/5) or x263(4/5) info in the video part in tree view.
    thx for detailed answer ;)
