Comment (by Tjoppen):

 Well, take a look at the way the packets in the file are ordered:

 {{{
 $ wget https://cloud.loewe.de/index.php/s/9QoEPe7lfsVTZjW/download
 $ ffprobe -show_packets download | egrep "stream|pos" | head -n200 | tail
 -n8
 [...]
 stream_index=0
 pos=480382
 stream_index=1
 pos=729963
 stream_index=0
 pos=482332
 stream_index=1
 pos=730315
 }}}

 Compared to a remuxed file:

 {{{
 stream_index=1
 pos=337372
 stream_index=0
 pos=337735
 stream_index=1
 pos=375978
 stream_index=0
 pos=376350
 }}}

 So yes, Wowza seems to be producing not-so-good files. But since remuxing
 the files fixes this, you could just always do that. I'd suggest reporting
 this to Wowza, or dropping them entirely.
