I was using the old PC method where you get your keys from Android Studio, manually grab the PSSH and bash cookies/headers and run through the l3 script and ffmpeg combine the decrypted audio/video files. Seems like searching for "widevine" in F12 and copying the curl(bash) for headers. Mid post, it all of a sudden says "unable to parse license - check protobufs. When it just worked 20 seconds prior on another video.
thoughts?
Edit: not sure what happened, but is working now. Couldn't find the OG instructions on the forum anymore.
