Failed to instantiate drm object

Hi,

Lately, a few users have faced crashes while playing movies with DRM content.
Here is how the app handles the DRM-stream:

fun createSourceConfig(mainStreamUrl: String, drmUrl: String): : SourceConfig {
       return SourceConfig(mainStreamUrl, SourceType.Dash).apply {
            val widevineDrm = WidevineConfig(drmUrl)
            val header: MutableMap<String?, String?> = HashMap()
            header["utoken-drm"] = "wv"
            widevineDrm.httpHeaders = header
            this.drmConfig = widevineDrm
        }
}

It works fine so far and only a few users experienced the crash.

I can not identify which movie triggered this issue. Could I prevent the crash using try catch? so I can silently send the crash report to the Firebase log for further investigation. Please let me know if you need more information.

Hi @puthea.mam,

thanks for reaching out. As far as I can see it at the moment there is no way of catching the mentioned exception.

We are tracking the issue internally and will update here once we have additional information available.

In the mean time you can try checking for supported DRM scheme using code similar to the following in order to prevent the crash.

MediaDrm.isCryptoSchemeSupported(/* DRM scheme, e.g. widevine */)

Sorry that I don’t have any better news as of now.

Best,
Lukas
