  • CDM/DRM Changes: Blank Screen-recording During Video Streaming

    Posted by Todd Gruel on November 11, 2022 at 4:21 am

    I am not sure which forum to post this in.

    I am a Mac user and I recently noticed that I have unilaterally lost the ability to screen capture online video for my recreational use: as soon as I attempted to record a snippet of a video, the streaming service would black out the screen. At first I thought that it was a fluke phenomenon particular to a certain internet browser or streaming platform. But after I tried a range of other browsers, platforms, and screen recording apps — including EaseUS, WinX HD, OBS, and MacX — all which had the same effect, I now realize that this is a new universal standard for all online content interaction.

    Has anyone else successively navigated this issue? Am I right in assuming that this is not a Mac-specific phenomenon? The fact that this same phenomenon occurs while attempting to screen record a DVD seems to suggest that Mac OS has also now been modified in its design.

    Can anyone educate me as to how this is related to Content Decryption Modules? What exactly is a CDM?

    I have also noticed that Firefox seems to give users the options of not complying with the now industry-standard technology requirements for streaming online content, yet that noncompliance seems to come at a consequence:

    “You have the choice to globally opt out of HTML5 DRM playback. Once you opt out, Firefox will delete any downloaded CDMs from your hard drive, cease all future CDM downloads and disable DRM playback.”

    I’m not trying to be provocative or controversial. Again, I have never used my screen recordings for anything other than recreational purposes. Although I understand that technology, and the powers that be who design it, cannot discern our intentions, I’m just trying to understand the recent changes that have occurred, so that I can adapt accordingly. Thank you for any help you can provide.

    It sounds like the issue you are experiencing is related to DRM (Digital Rights Management) protection implemented by streaming services and other content providers to prevent unauthorized copying or distribution of their content. When you attempt to screen capture or record a video, the DRM protection may detect this activity and block or interrupt the video playback.

    A Content Decryption Module (CDM) is a software component that is used by web browsers and other software applications to decrypt and play DRM-protected content. CDMs are typically provided by the content providers themselves or by third-party DRM solutions.

    It’s possible that the streaming services and other content providers have recently updated their DRM protection to detect screen recording and prevent it from occurring. This is not a Mac-specific issue, and the same restrictions apply to users on other platforms as well.

    Regarding the Firefox option to opt out of HTML5 DRM playback, it’s important to note that doing so may prevent you from accessing certain content that requires DRM protection. Additionally, disabling DRM playback may be a violation of the terms of service for some streaming services and could potentially result in account suspension or legal action.

    If you are experiencing issues with screen recording and would like to continue doing so for recreational use, you may want to consider using a different method such as a physical camera or a separate device to record the video playback. However, it’s important to be mindful of copyright laws and to only use recorded content for personal use and not for distribution or profit.
