"Source Error"

I am a new user of Sparkle Player and I have some channels in my m3u that are giving a "source error". This type of channel play very well in tivimate and ott navigator. They are channels that uses a widevine license. Here is an example:

​

#EXTINF:-1 channel-id="pbs-WPBT" tvg-id="WPBT" tvg-logo="https://image.pbs.org/stations/wpbt-color-cobranded-logo-QKMOlbI.png" , WPBT South Florida PBS

#KODIPROP:inputstream.adaptive.manifest_type=mpd

#KODIPROP:inputstream.adaptive.license_type=com.widevine.alpha

#KODIPROP:inputstream.adaptive.license_key=https://proxy.drm.pbs.org/license/widevine/b675a937-fe2b-43bf-bc43-fa8d97c330e5-dash|Content-Type=application%2Foctet-stream

https://wpbtdt.lls.pbs.org/out/v1/46efda8fe4f94ee0a86b868c1f44f411/dash-drm.mpd

​

Does Sparkle Player uses another way of formatting the channel or is the case that it just doesn't support it?
