Sometimes after we download movies online, the movie file turns out to be a BDMV folder instead of a separate video file like MP4 or MKV.
To those who have no idea what this is, the BDMV folder is ripped from a movie Blu-ray disc and it contains the movie clips. Compared to a regular movie file, it takes some effort to play. We can stream it on the computer with a BDMV player app and watch the movie.
In this article, we will first explain what is BDMV. Then, we will introduce a practical BDMV player that can help you stream the movie on the computer. Also, the detailed steps will be displayed. Read on.
Part 1: What Is BDMV
To begin with, there are two meanings when we talk about BDMV.
The first one is the BDMV folder. A Blu-ray disc normally consists of 3 general folders,
- AACS (sometimes BD+ or ROM Mark)
This is what you will see in the first place as you launch the movie folder.
The BDMV folder stores the major data of the Blu-ray movie including the movie, audio tracks, subtitles, movie directory, and other movie content.
The BDMV comes from a Blu-ray disc and it’s exactly what you need to play the movie. People can rip it out from the disc so that you don’t need that Blu-ray disc to watch the movie anymore. Also, some people will upload the Blu-ray movie folders online so that others can download the movie as local files.
What Is A .bdmv File?
Inside this BDMV folder, we will surprisingly find some files with the .bdmv extension, such as index.bdmv, MovieObject.bdmv, and sound.bdmv.
Each file contains one type of data. Case in point:
- Index.bdmv: the directory of Blu-ray movies;
- MovieObject.bdmv: the information for all clips;
- Sound.bdmv: the audio track information.
Compared to the BDMV folder, these files in bdmv first cannot be played by any media player since this is not a media format at all. You can take them as locators – while streaming the BDMV folder, these .bdmv files help you play the movie correctly.
So, don’t bother to play the .bdmv file. Focus on the playback of the BDMV folder then.
