fine here with ffplay and can be transcoded with ffmpeg. Could you explain
(again) what is wrong with the output file?
Now that you have that "out.ts", attempt to remux it to HLS(mpeg-ts)
segments, like what I tried. Then you'll see the problem.
ffmpeg -i out.ts -map 0 -sn -codec copy -bsf:v h264_mp4toannexb -f
ssegment -segment_format mpegts -initial_offset 10 segmentName_%04d.ts
