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

Wowza Streaming Engine

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.

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

Hi, Daren.

It needed in Wowza.

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