How to play encrypted contents?
Posted: 17 Feb 2016 17:44
I had an mp4 file, which I packaged and encrypted for Fairplay HLS using mp4split (from Unified Streaming) as described here: http://docs.unified-streaming.com/docum ... e-fairplay. I have the encryption key and iv used and I have the .ts segment files produced. Is there a way I can ask vlc to play this .ts file?
Original mp4 source:
Output produced by mp4split (there are 5 segments ("xxx_output_[0-4].ts"), in case you're wondering why the durations are different):
PS: Somehow the audio stream is missing from output .ts files. I'm trying to debug this.
Original mp4 source:
