Getting video bitrate

[grv575]

I'm trying to get the video bitrate from the commandline (for use in a script). My strategy currently is an avisynth script:

DirectShowSource("file")
filename = "c:\output.txt"
WriteFileStart(filename, "FrameCount/FrameRate")

This seems to work to get the video duration in seconds. My problem is running the avs script opens my media player. I don't want to play the video, just get the duration and exit. How would I do this in avisynth?

I think avisynth does not convey any information about bitrate

You could use mediainfo, I think you might be able to use it in a command line. This only reads header information and may or may not be accurate.

If it's video only (or subtract the audio), you could use a math formula since filesize=bitrate x running time , and you can fugure out running time and filesize

Yeah that's what I'm doing (the math formula). I've found avsutil does what I want.
