DRM support

[GitGud31]

My company is building an OTT app with Flutter for a big client, but till now we couldn't find a video player for Flutter that supports DRM (Android, iOS and Web). Does flutter_meedu_videoplayer support DRM videos ?

What is drm videos?

[GitGud31]

DRM stands for Digital Rights Management, it's a protection solution that helps content producers protect their video streams with top-grade encryption. Different Platforms propose different SDKs for DRM video protection that you can read about here: Apple's, Google's, Microsoft's.

I hope this helps

[abdelaziz-mahdy]

If video_player can handle it it will work, if mpv can handle it media_kit should handle it

I use both, you can switch between them

[GitGud31]

I don't think they do, but i'll give it a try and let you know, cheers!

EDIT: better description

Here's the dataSource schema for the video

{
        "name": "HD (cenc)",
        "uri": "https://VIDEO_MPD_LINK_HERE.mpd",
        "drm_scheme": "widevine",
        "drm_license_uri": "DRM_LICENSE_LINK_HERE"
},

there's no place/attribute to where to put the drm_license_uri to be sent and it's required to stream the video because without it, we get this error:

Notice the 'Caused by' error (403), since we didn't ask to check for DRM the license.

[abdelaziz-mahdy]

Can't these values get sent as http headers?

[GitGud31]

I don't think so no, I'll try to make a demo app with drm content links so you can test it if you can/want, because the links I have to sensitive and I can't share them.

[hkarmoush]

A solution that's worth looking into is using native code, there are multiple video players with DRM support out of the box on either iOS/Android maybe look into Bitmovin/Theo and integrating it with your flutter app using method channels.

I have used Bitmovin for a VOD platform and it was an enjoyable experience in their documentation.

[abdelaziz-mahdy]

Sadly I can't have the time to implement those, so I can't provide support to it if its not supported by video_player or media_kit

If you are able to implement those I recommend creating a package with your work, which will help people greatly with the same requirements.

And If you do create one , let me know, I may be able to integrate it into my package

@zezo357 I totally agree this is a time consuming task, my comment was more tailored as an advice for what's possible for @GitGud31

Yes and thank you very much for your help, I was just explaining my side since I will not be able to implement it, just to keep the hopes in check from my side 😢

[GitGud31]

I am open to try and help Implement DRM Support and configuration if you're interested. (I work full time, I can only work on this on the weekends)

Sadly you will have to ask media_kit for it, since I can't and don't handle the video playback itself media_kit and video_player does it.
