Comment (by Vitaly Ivanov):

 It's a long shot, but can you recommend a method to work around this
 issue? I need to produce an encrypted fmp4 which can be played by ffmpeg
 prior to "avformat/mov: fix frag_index.current out of sync". I'm creating
 a video-only stream with every single frame in its own segment, single
 traf/trun, nothing fancy. Here's an example (-decryption_key
 abcdef0123456789aabbccddeeff0011):
