@aik099 trying to get this to work... the script seems to start ok but fails when running
combineCmdwith :seems like ffmpeg needs more info? is there some extra flags to give ffmpeg that could help?
EDIT: adding more info. Looking further into the
ffmpegerror I saw someone suggested the data may be encrypted. I coincidentally noticed this on my console while streaming the video in questionSome forums related to encrypted video in general suggested a key might be available to decrypt but this is where i hit a wall with my knowledge. Could there be a decription key somewhere we could use? or is this a blocker related to DRM stuff?
