You should probably squash this with the other patch, into one commit.
-Makes it possible to use segment indexes as %%d besides date/time values when
use_localtime is on.
+Makes it possible to use segment indexes as %%d in hls_segment_filename
expression besides date/time values when use_localtime is on. To get fixed
width numbers with trailing zeroes, %%0xd format is available where x is the
required width.
You could break these lines (texinfo formatting will handle the real
representation later), but I'm not sure it's totally necessary.
+@example
+./ffmpeg -loglevel info -y -f lavfi -i color=c=red:size=640x480:r=25 \
+ -f lavfi -i sine=f=440:b=4:r=44100 -c:v mpeg2video -g 25 -acodec aac
-cutoff 20000 -ac 2 -ar 44100 -ab 192k \
+ -f hls -hls_time 3 -hls_list_size 5 \
a) replace ./ffmpeg with ffmpeg (as most users would expect to use it),
b) please use simpler syntax for the stuff not related to what you are
trying to document; i.e.: ffmpeg -i input.mov -f hls -hls_time 3 -hls_list_size
5 [...]
+This will produce segments like this:
+@file{segment_20170102194334_0003_00122200_0000003000000.ts},
@file{segment_20170102194334_0004_00120072_0000003000000.ts} etc.
I have made the suggested modifications.
The rest seems fine to me!
Moritz
