Description
Summary of the bug:
the output single file segment is not encrypted and when I remove the EXT-X-KEY tag I can play it using a normal video player.
while previous versions of ffmpeg encrypted the single file successfully, but the output byte ranges were wrong.
How to reproduce:
ffmpeg -i test.mp4 -hls_flags single_file -hls_key_info_file key.info playlist.m3u8 ffmpeg version: latest snapshot
log :
ffmpeg -i test.mp4 -hls_flags single_file -hls_key_info_file key.info playlist.m3u8
