Hi, I'm trying to download a encripted video using mediafilesegmenter with SAMPLE-AES, not fairplay... I can play the video online without any problems.. When i try download the video using AVAssetDownloadTask I get an error: Error Domain=CoreMediaErrorDomain Code=-12160 "(null)" And, if I use ClearKey system to deliver the key when I have a custom scheme on the m3u8, Airplay doesn't work either Sample-aes only works with fairplay? I can't find any information about it, does anyone know if it is a bug? I hope someone can help me :)
