How to get number of I/P/B frames of a video file?

I want to extract information of a video file to get the count of its I/P/B frames. How to do it in ffmpeg? Or should I programming using libavformat and libavcodec to do it? Many thanks!

Solution

  • On the command line use ffprobe -show_frames input_file. you can parse this input to get the frame type information.

    You can also do ffprobe -show_frames inputfile | grep pict_type

    The string to grep may vary depending on version of ffprobe you have.
