I've been sent an .ogv file by a video company that's 4 times the file size of the equivalent MP4 file. I suspect they've encoded it at way too high a bitrate, but I'd like to check for sure.

I'm on Windows 7 (64bit) but have other OSes (e.g. Mac OS 10.8.5) available too.

I've tried using the 'media information' window in VLC media player - but for some reason that only shows the bitrate of the audio stream, not the video stream!

I've also tried installing the XIPH Directshow filters in the hope that this might make Win7 show the encoding detail in Windows Explorer or via Media Player, like it does for MP4 files - but no joy.

You can install ffmpeg for windows

Use it like this

ffmpeg.exe -i file.ogg

Output will be like this

The bitrate is at the line
