How to see media files (namely `flv`) details/info in Windows 7?

I see that for many media files, under Properties/Details there are some needed info like audio/video bitrate, but it seems limited - for example it does not work for flv.

Is there a way that would extend this possibility?

I was trying to convert some files to mp3, and in order to do that properly i have to know what is the input bitrate in order to set the same for output

I am aware that superuser discourages asking for a specific program: I am not asking for that, but for a generic answer - what to do about it in general.

I had a comment saying:

(i) there is no such ONE tool for all media files;

(but i see that win7 already does that except for flv. why?)

(ii) that i need a tool that 'supports' flv.

(what does that mean? i already can convert and play the flv but know nothing about the audio bitrate)

Solution 1:

You can try MediaInfo

It is a freeware and puts a right-click context menu item so that you can quickly get info about most of the media files.

Also as an addition, try Free Studio: http://www.dvdvideosoft.com/free-dvd-video-software.htm
It has a host of media conversion tools including dedicated tools for flash(flv) videos. If I remember correctly, these flv converters allow you to keep the bitrate same while conversion so you don't have to bother checking bitrate for each file.
