 And here is the interesting part. There is a little manipulations with
 this dump, after which ffmpeg transcodes it more stable.

 {{{
 dd if=/root/squared_cut.ts of=/tmp/bad_tail.ts bs=188 skip=1034300

 dd if=/tmp/bad_tail.ts of=/tmp/c2.ts bs=188 count=3883 && dd
 if=/tmp/cut.ts of=/tmp/c3.ts bs=188 skip=5113 && cat /tmp/c2.ts /tmp/c3.ts
 > /tmp/good_cut.ts
 }}}

 So after this manipulations we get good_cut.ts dump which transcodes fine
 - at least decoder not fails unrecoverably.
 Sorry the dump quite huge, because I'm not sure which part of it actually
 lead to bug. So I uploaded it on yandex.disk and turn on access by link:
