    Default What would be the best thing to validate keyframe and codec.

    I need to validate video codec and keyframe frequency.

    * keyframe frequency should be under 5 sec
    * video codec should be H264

    How would you tell me whether it is good each?

    Hi,
    FFPROBE (part of FFMPEG)

    This command with help list keyframes:
    ffprobe -select_streams v -show_frames -v quiet in.mp4


    also, ffprobe -i filename works well to find codec information.

    Hi, Daren.

    It needed in Wowza.

    "video codec should be H264" could be validated at IMediaStreamActionNotify3#onCodecInfoVideo, how about keyframe?

    This question is not quite clear. Did you follow the steps provided by Daren in his reply?
