Comment (by pero):

 It behaves the same with the latest git version.

 I simplified ffmpeg parameters a bit:
 {{{
 ffmpeg -rtsp_transport tcp -i "rtsp://x.x.x.x:554/h264/ch1/sub/av_stream"
 -an -c:v copy -f hls -hls_time 4 -hls_list_size 5 -hls_flags
 +delete_segments -hls_flags +append_list -hls_flags +omit_endlist
 -hls_flags +discont_start output.m3u8
 }}}

 output:
