Hi all,
we want to play downloaded encrypted HLS Fragment MP4 files on iPhone, and we are using UsingAVFoundationToPlayAndPersistHTTPLiveStreams to test. on this HLSCatalog app, we can playback encrypted HLS Fragment MP4 streaming, but when we download the encrypted HLS Fragment MP4 to device/iPhone, then try to playback on device, but now, it has an issue:The error is: Error: Optional("The operation couldn’t be completed. (CoreMediaErrorDomain error 1718449215.)")
So, we want to know how can I playback downloaded encrypted HLS fmp4 on iPhone. and you can try below url: http://69.234.244.220/prod/vod/HDR10_2D_LEFT_48FPS_FMP4_Encrypted/prog_index.m3u8
Steps to reproduce:
1: create a HLS fragment mp4 with mediafilesegmenter: mediafilesegmenter --iso-fragmented -t 4 --encrypt-key-file=BT709-2D-48FPS.key --encrypt-key-url=http://69.234.244.220:5000/download/BT709-2D-48FPS.key -f prod/vod/HDR10_2D_LEFT_48FPS_FMP4_Encrypted HDR10_2D_LEFT_48FPS.mp4
