When use %s parameter for the segment filename, it will get error message
with Invalid
segment filename template, so add the use_localtime option fix it, the
default value is
14 for the segment filename.
the test example:
./ffmpeg -re -i ~/Movies/objectC/facebook.mp4 -v verbose -c copy -f hls
-hls_segment_filename test-%s.ts -use_localtime 1 -bsf:v h264_mp4toannexb
