Comment (by Igor_Selivanov):

 1. As far understand from your comment, attached example dvbt2_small.ts is
 not DVB conform. Loewe TV saves one program from transponder stream.
 Transponder stream contains multiply channels. It seems that by saving
 stream on hard drive AAC stream is modified and not DVB conform any more.

 We compared incoming stream from German television with saved on hard
 drive. Indeed, stream Id is changed from 0x11 to 0xF. This is probably
 reason of this bug. Changing stream Id back to 0x11 fix issue of this
 topic.

 Internally we created ticket in Loewe bug tracking system. Our DVB experts
 will investigate this.

 2. Unfortunately workaround that you committed, doesn't work with attached
 example. I would propose to revert it, because attached example is not DVB
 conform. Sorry for this and thanks for your time.

 FFmpeg library is great tool. Number of supporting formats is amazing. It
 helps everybody to develop great product. Thanks a lot.
