A command line program that outputs one of the following:
[1] A graph showing the bitrate every second. The graph can be "filled" or "unfilled".
Unfilled graph example:

Filled graph example:

[2] Information about every Group of Pictures (GOP). You must use the -gop argument if this is what you are looking for. Only applicable if analysing a video file. Here's an example of the output:
Detected the following info about BigBuckBunny.mp4: ---------------------------------------------------- Duration: 596.474195s Number of Frames: 14315 Framerate: 24.0 FPS ---------------------------------------------------- GOP Statistics: GOP count: 266 Average number of packets per GOP: 53.8 GOP duration range: 0.500s to 2.500s Average GOP duration: 2.242s GOP size range: 0.54 to 9.09 Megabits GOP bitrate range: 0.51 to 4.07 Mbps Average GOP bitrate: 2.00 Mbps ✓ Average PTS interval matches expected frame rate ✓ PTS intervals are consistent [Info] GOP durations are inconsistent: Min GOP Duration: 0.5000006666665892 Max GOP Duration: 2.5000006666667027 - Python 3.7+

You can find the output of python main.py -h below:
usage: main.py [-h] -f FILE_PATH [-dts] [-gop] [-g {filled,unfilled}] [-s STREAM_SPECIFIER] options: -h, --help show this help message and exit -f, --file-path FILE_PATH Enter the path of the file that you want to analyse. If the path contains a space, it must be surrounded in double quotes. Example: -f "C:/Users/H/Desktop/my file.mp4" -dts Use DTS instead of PTS when calculating bitrates. Only applicable if analysing a video file. -gop Output information about every Group Of Pictures (GOP). Only applicable if analysing a video file. -g, --graph-type {filled,unfilled} Specify the type of graph that should be created. The default graph type is "unfilled". To see the difference between a filled and unfilled graph, check out the example graph files. -s, --stream-specifier STREAM_SPECIFIER Use FFmpeg stream specifier syntax to specify the audio/video stream that you want to analyse. The defaults for audio and video files are a:0 and V:0, respectively. Note that stream index starts at 0. As an example, to target the 2nd audio stream: --stream-specifier a:1
