the output files, each should be checked against a md5 stored in git
also the whole should be demuxed again (with framecrc) and that too
compared against the good framecrc output in git.
theres no real reference file for the fate-suite for this as theres
not one correct ts file set. slight changes in the ts muxer or
encoders would change the output

If a bugfix only changes things apparently unrelated to the bug with no
further explanation, that is a good sign that the bugfix is wrong.
