ssegment muxer reset continuity counters on each segment regardless of reset_timestamps option value

[Bela B]

Summary of the bug:
ssegment muxer reset first continuity counters to zero in each segment regardless of reset_timestamps option value, but it should not do this. The continuity counters should be counted seamlessly in case of reset_timestamps value being 0.

How to reproduce:

% ffmpeg -f lavfi -i testsrc -t 120 -f ssegment -segment_format mpegts -reset_timestamps 0  -segment_list out.csv sout%d.ts

Then inspect sout1.ts and sout2.ts with tsreport:
% tsreport -cnt 256 sout1.ts

The last line of output is:
CC: first: 0, last: 11; duplicate packets: 0

(or see the content of continuity_counter.txt)

tsreport -cnt 256 sout2.ts

The last line of output is:
CC: first: 0, last: 15; duplicate packets: 0
(or see the content of continuity_counter.txt)

But it shoud be something like:
CC: first: 12, last: ...

the full output of commandline of "ffmpeg -report ..." is enclosed as attachment.

Please test current FFmpeg git head.

I have done. The result is as bad as earlier. The new full command line output is enclosed as attachment.

Setting individual_header_trailer to 0 will (probably) achieve what you want.
