 You don't waste your time, you will be happy when you'll enable the ad-

 The commflags settings require some times to get results.

 The logo flag detection works in the branch master : to convince you, try
 it with my sample ![1] ![2].

 I tested your sample z.ts with branch master. The different behavior comes
 from your sample.

 * In v29 : It correctly detects the frame rate.
 * In v30 : For unknown reason, the new libav detects a wrong frame rate at
 50/s. With my sample the frame rate detected is ok. You can see that if
 you enable the libav logs (-v libav).

 So, If you modify the setup according that
 (!CommDetectLogoSamplesNeeded=15), It works with your sample ![3].

 ![3] logs in v30 with new settings on your sample z.ts
