When you intend to use FFmpeg to convert DCV videos purchased from DMM to MP4 format, you may make mistakes with the operation or fail to transfer the downloads to MP4 because of the lack of knowledge about FFmpeg.

No worries! In this article, we will show you why FFmpeg cannot download DMM videos, how to convert DMM videos from DCV format to MP4 format for free, and how to make it successfully without effort.

What is FFmpeg?

FFmpeg is a free program that can convert video formats and edit videos. It's used through a command line interface. You can easily change videos to different formats with FFmpeg.

What is FFmpeg?-1

Unfortunately, we haven't found a way to use FFmpeg to convert your purchased videos (DCV files) on DMM to MP4. Also, when playing DMM videos saved with FFmpeg, the screen might go black. Similarly, when you use a capture tool to screen record DMM videos, your screen will turn black too.

Why Can't I Download DMM Videos with FFmpeg?

Recently, more and more questions about converting DMM videos to MP4 have appeared on WisdomBank. Many of you may be wondering how to convert DMM videos from DCV to MP4. The following is a collection of the most notable questions from Wisdom Bukuro. 

Q1: "I want to convert DMM video in DCV files to mp4, is there any good software to do this? I tried with FFmpeg but it didn't work with a blank screen and only 1 second output."

Q2: "Please tell me how to convert a video in dcv format downloaded from DMM to MP4 format. Please."

Q3: "Please tell me how to convert a dcv file I purchased and downloaded from DMM to mp4 and another way to watch it. The file is 4.86 GB in size and could not be converted using existing software. Also, I tried FFmpeg but the installation did not work. Please advise."

It's obvious that downloading DMM videos with FFmpeg doesn't work. This is because DMM videos, even purchased ones, are saved as DCV files with DRM protection.

FAQs

Q1. Can I use GOMPlayer to play DCV videos purchased from DMM?

A1. GOMPlayer is a Windows player that can play various video formats like AVI, MP4, MKV, FLV, WMV, and MOV. However, if you try to play the purchased videos (DCV files) directly in GOMPlayer on an offline computer, it won't work.

To watch DMM videos in GOMPlayer, you'll need to convert the DCV files to MP4, MKV, or another format. We recommend using KeepStreams to download and convert the titles easily.

Q2. Is it illegal to convert DMM videos from DCV format to MP4?

A2. Downloading from DMM Video isn't illegal, but it could lead to legal issues if it's considered damaging to business profits. This is especially true for copyrighted content. Renting, transferring, selling, showing, or publishing copyrighted content online is strictly prohibited.

It's important to use these tools legally. Only download for personal enjoyment or storage, and do so in moderation. Respect copyrights and avoid infringing on others' rights.

Q3. How do I convert DMM videos to MP4 on my Mac?

A3. The success rate of converting DMM videos to MP4 format using FFmpeg is particularly low for both Windows and MAC, so it is quite difficult to convert DMM videos to MP4 on MAC without using a professional application.

While KeepStreams for DMM TV also has a Mac version, Mac users can easily convert DMM videos from DCV to MP4. Now give it a try for free for 3 films!
