Hi @barbibulle,
I am facing playback issue in edge browser with Bento4 cbcs encryption. Have used the following packaging command,

bento4/bin/mp4dash --encryption-cenc-scheme=cbcs --encryption-key=xxxx:xxxx:xxxx --use-segment-timeline --widevine --widevine-header=https://xxxx.com --playready --playready-version=4.3 --playready-header=https://xxxx.com --hls --fairplay-key-uri=skd://xxxx_token test.mf4

I am using Pallycon multi DRM services for license. As per Pallycon,

- In the PlayReady pssh data of your DASH mpd, there is "CHECKSUM" value as below. 
- It should be removed to set the encryption mode (ALGID) as AESCBC. (refer to this document)
- It seems to be a bug in bento4 mp4dash module.

Could you please look into this on priority?
