 Summary of the bug:

 When sending the chunks via the HTTP PUT method the init.mp4 file is not
 created on the remote path. When supplying a init.mp4 manually in the
 playlist the manifest does not play anywhere. This could be due to the
 init.mp4 being incorrect or because of something else. Is the init.mp4
 stream specific or is it possible to generate a generic one?

 How to reproduce:
 {{{
 % ffmpeg -i bbb.avi -loglevel warning \
      -hls_fmp4_init_filename init.mp4 -c:a aac -b:a 128k -ar 44100 -c:v
 libx264 -max_muxing_queue_size 400 -x264opts no-scenecut -force_key_frames
 "expr:gte(t,n_forced*2)" -crf 23 -start_number 0 -hls_time 4
 -hls_list_size 3 -use_localtime 1 -hls_segment_type fmp4
 -hls_segment_filename "${REMOTE_PATH}/segment_%s.m4s" -preset ultrafast
 -profile:v main -level 3.1 -r 30 -threads 0 -vf "scale=-2:720" -bufsize
 2000k -maxrate 2000k -b:v 2000k -f hls -method PUT
 "${REMOTE_PATH}/playlist.m3u8"

 ffmpeg version 3.3.3

 }}}

 Error:

 [hls @ 0x7fa09a00ca00] Failed to open segment 'init.mp4'
 Could not write header for output file #0 (incorrect codec parameters ?):
 No such file or directory

 Patches should be submitted to the ffmpeg-devel mailing list and not this
 bug tracker.
