Help with GoPro Hero 4 mpegts stream on iOS

[dkabyshev]

Hi,

I'm trying to use GStreamer (1.5.2) to play live feed from GoPro Hero 4
Silver. 
I've been experimenting a lot and faced with an issue, that tsdemux can't
process frames, because, as I assume, time information is missing, here's a
link to debug log:
https://www.dropbox.com/s/0vef4jqv8xce0mm/gopro_mpegts?dl=0
<https://www.dropbox.com/s/0vef4jqv8xce0mm/gopro_mpegts?dl=0>  

As a minimum test, I was trying this pipeline: udpsrc port=8554 !
video/mpegts, systemstream=(boolean)true ! tsdemux ! video/x-h264,
stream-format=(string)byte-stream, alignment=(string)nal ! fakesink

I would really appreciate any help on this.
I was able to test the stream from from GoPro with ffprobe and ffplay:
