Comment (by alexey.rodionov):

 I've found that running

 {{{
 ffmpeg -i input.mp4 -f hls -hls_enc 1 stream.m3u8
 }}}

 now successfully randomly generates the key, but not the initialization
 vector (IV):

 {{{
 #EXTM3U
 #EXT-X-VERSION:3
 #EXT-X-TARGETDURATION:4
 #EXT-X-MEDIA-SEQUENCE:9
 #EXT-X-KEY:METHOD=AES-128,URI="stream.m3u8.key",IV=0x00000000000000000000000000000000
 }}}

 Is it ok? Shouldn't the IV be randomly generated too, if the `-hls_enc_iv`
 option is omitted (as it is for the key if the `-hls_enc_key` option is
 omitted)?
