DRM issue with video_player_avplay 0.5.6

[Nygashi]

Hi Flutter-Tizen team!

I’m using the 'video_player_avplay: 0.5.6' plugin to play video streams in my Samsung Tizen app.
But, when I try to play Widevine or PlayReady DRM protected content on a Samsung QE32Q50AAU (2021) with Tizen 6.0, this fails with the following error:


Error: Not supported media format
PlatformException([PlusPlayer] error, Error: Not supported media format, null, null)

When I try to play the exact same stream with Widevine DRM protection on a Samsung QLED 55Q64B (2022), this works fine.

What I tested and tried so far:

• Playing a stream with Widevine DRM protection works fine on the 55Q64B
• Playing a stream without DRM protection works fine on the QE32Q50AAU
• I tried using Widevine AND PlayReady, but both fail with the same error message that was stated earlier on the QE32Q50AAU
• I made sure that I’m using a partner signed distribution certificate for both TV's, so that DRM is supported when running the app.
• I'm using the 'licenseCallback' from the 'VideoPlayerController.network', so that I can send the challenge to my license acquisition endpoint.
• I added the required permissions to the tizen-manifest.xml:

   <privileges>
        <privilege>http://tizen.org/privilege/mediastorage</privilege>
        <privilege>http://tizen.org/privilege/externalstorage</privilege>
        <privilege>http://tizen.org/privilege/internet</privilege>
        <privilege>http://developer.samsung.com/privilege/drmplay</privilege>
    </privileges>

Questions I have:

• What is it that I’m doing wrong?
• Is there an overview of what DRM types should be supported by those TV models? As I found that both models should be able to handle 'Widevine DRM', which has my preference.
• Is this a known issue?

Any help would be greatly appreciated, as I would really like to support all Samsung Tizen TV models with Tizen 6.0+. This issue is currently blocking me to go live.

Thanks in advance!

Hi, Thank you for your interest.

This issue may really be a video format issue, but there is one part where the issue is expected.

What is the api-version written in the app's tizen/tizen-manifest.xml?
video_player_avplay requires the api-version and the tizen version of the TV to be the same.
So if the 2022 TV is Tizen 6.5, you should write the api-version as 6.5 and build it,
and if the 2021 TV is Tizen 6.0, you should write the api-version as 6.0.

Note that video_player_avplay uses a compiled dynamic library, the api-version is your TV version, change it in tizen-manifest.xml:

We recently updated the package to 0.5.7. I recommend testing on the latest version.
