I'm tying to split mov file to .ts segments with m3u8 playlist. All is ok except of audio. Audio doesn't work and it seems that ffmpeg ignores audio stream.
This is my command:
ffmpeg -i stepteen2.mov
-c:a aac
-c:v libx264
-an
-map 0
-muxdelay 0
-muxpreload 0
-output_ts_offset 0
-segment_time 2
-segment_wrap 1000
-segment_list_size 0
-segment_list temp.m3u8
-segment_list_flags +cache
-segment_list_type m3u8
-f segment
temp-%03d.ts
After this command I receive 5 ts segments and m3u8 playlist with segment paths list. If I open properties of segment files there are no any information in Audio and Video tabs (although video works)
This is output:

Remove -an. This option means "no audio".
