Comment (by liuzceecs):
sorry, sir, can you provide the log of segmentation? cause the length of
every m4s file is pretty OK on my Ubuntu 15.10 with the lastest version
ffmpeg.
Here is my command
{{{
ffmpeg -i source.mp4 -an -sn -vcodec libx264 -force_key_frames
"expr:gte(t,n_forced*4)" -sc_threshold 0 -r 25 -f hls -hls_time 4
-hls_list_size 99999 -start_number 1 -hls_segment_type fmp4
-hls_fmp4_init_filename init.mp4 -t 30 -threads 0 big_bunny.m3u8
}}}
Then I get 8 m4s files. The first 7 is 4 seconds long and the last one is
2 seconds long.
'''But what is pretty interesting is that my m3u8 file is pretty weird.'''
{{{
#EXTM3U
#EXT-X-VERSION:7
#EXT-X-TARGETDURATION:4
#EXT-X-MEDIA-SEQUENCE:1
#EXT-X-MAP:URI="init.mp4"
#EXTINF:4.000000,
big_bunny2.m4s
#EXTINF:4.000000,
big_bunny3.m4s
#EXTINF:4.000000,
big_bunny4.m4s
#EXTINF:4.000000,
big_bunny5.m4s
#EXTINF:4.000000,
big_bunny6.m4s
#EXTINF:4.000000,
big_bunny7.m4s
#EXTINF:2.000000,
big_bunny8.m4s
#EXT-X-ENDLIST
}}}
It misses the first m4s file. I am still working on that bug. But I need
to first figure out why your ffmpeg provide different results from me.
