MediaInfo: free tool to see what is inside a video or audio file
MediaInfo calls itself open-source software with a BSD-style licence. It shows you the codec, bit rate, resolution and tags inside a media file, which helps when a video will not play or you want to know what you downloaded. Here is what its pages say.

What it is
MediaInfo is a project of MediaArea. Its site describes it as "a convenient unified display of the most relevant technical and tag data for video and audio files". You open a file with it and it lists the details: the container format, the video and audio codecs, bit rates, subtitle tracks and chapter marks.
Is it free?
On desktop, yes, per the project. The licence line on its page says: "It is Open-Source software which means that end users and developers have freedom to study, to improve and to redistribute the program (BSD-style license)." The downloads page charges nothing and the site asks for donations to support development.
On phones and in app stores it is not fully free. The iPhone app and the official Android app (from MediaArea.net on Google Play) are free to download with optional in-app purchases that unlock more features; the US App Store lists these at $2.99 a year or $7.99 lifetime (about ₹285 or ₹760). The Mac App Store version is a paid listing at $0.99 (about ₹95) with the same optional extras; the free choice on a Mac is the download from mediaarea.net. The browser version, MediaInfoOnline, is free to use.

Our advice
- Use it before you convert or delete a file: one look tells you the codec and quality. This is our advice, not the project's.
- If a video has no sound on your TV, check the audio codec with MediaInfo first. It often explains why.
- Download from mediaarea.net only.
Privacy and data
- We could not read a privacy statement on the pages we checked (the privacy link redirected) and make no claim about data. The desktop program reads files on your own computer.
India
- No region limit appears on the pages we read. We did not test it from India.
