 Summary of the bug:
 the muxing overhead when creating .ts files using FFMPEG is too large,
 often exceeding 25% for certain .ts files

 How to reproduce:
 {{{

 ffmpeg.exe -i input/128p164k.mp4 -codec copy -map 0 -f stream_segment
 -segment_time 3 -segment_time_delta 1 -segment_list out/128p164k.m3u8
 -bsf:v h264_mp4toannexb out/captain_america_Stream1_128p164k-%d.ts

 }}}
