vtdec: "Error decoding frame -12909" on iOS

Submitted by Andrey

Description

I have cloned this repo http://cgit.freedesktop.org/~slomo/gst-sdk-tutorials/tree/gst-sdk/tutorials/xcode%20iOS and run Tutorial 5 in XCode 7. Wowza rtsp sample video works fine. But my IP camera shows only first frame of video and fire PAUSED state.
Similar IP camera rtsp links works fine in VLC and Android version of GStreamer.

I have implemented tutorial sample in my application and have got similar behavior.
Here is log of GStreamer http://pastebin.com/9N54vQUb captured from my application.

Logs have a lot of

"0:01:05.669427000 [335m 178[00m 0x183559e0 [32;01mFIXME [00m [00;01m bin gstbin.c:4070:gboolean gst_bin_query(GstElement *, GstQuery *):[00m implement duration caching in GstBin again"

and

"733:gst_vtdec_session_output_callback:<vtdec0>[00m Error decoding frame -12909
0:00:09.393987000 [336m 5105[00m 0x159570a0 [31;01mERROR [00m [00m"

messages.

How can I fix it?

Thanks for advance!
