Comment (by dlevinson5):
Using "ffmpeg -i big_buck_bunny_480p_h264.mov -t 120 output.m3u8" does
produce .ts segments with the correct continuity counter.
Using "ffmpeg -i "big_buck_bunny_480p_h264.mov" -c copy -map 0 -vbsf
h264_mp4toannexb -f segment -segment_time 10 -segment_list_type m3u8
-segment_list index.m3u8 -segment_format mpegts segment_%d.ts" reproducts
the issue where the continuity counter it reset to 0.
You can inspect the continuity counters using the following command
tsreport command from the tstools package available from Google Code
(http://code.google.com/p/tstools/).
(correctly shows the counters in each filing picking up where it left off
in the prior file)
tsreport -cnt 256 "output1.ts"
type continuity_counter.txt
tsreport -cnt 256 "output2.ts"
type continuity_counter.txt
(incorrectly shows the counters resetting to 0 on each file)
tsreport -cnt 256 "segment_0.ts"
type continuity_counter.txt
tsreport -cnt 256 "segment_1.ts"
type continuity_counter.txt
