How to read an specified frame from an MPEG-TS video file?

[Yashil]

I am trying to write a code that help me to grab e.g. frame #120 from a given
mpeg-ts video file.

I am new to gstreamer. I tried several methods but have not reached my goal
yet.

The best example I found so far is
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/manual/html/section-data-spoof.html#section-spoof-appsink

but when I use the above code to read an example .ts file
https://dl.dropboxusercontent.com/u/43104344/mpts_out.ts
or several of my own .mts files it fails to pull-preroll and gives the
following error messages:
         No accelerated IMDCT transform found
         0:00:00.405110839  4632   0B775380 ERROR                  libav
:0:: get_buffer() failed (-1 2 00000000)
         0:00:00.405740899  4632   0B775380 ERROR                  libav

         0:00:00.416044436  4632   0B7759C0 ERROR                  libav
:0:: Cannot combine reference and non-reference fields in the same frame
         0:00:00.416813339  4632   0B7759C0 ERROR                  libav
:0:: decode_slice_header error
         0:00:00.417725301  4632   0B775CE0 ERROR                  libav
:0:: Missing reference picture

The above errors even occurs sometime when I just simply want to play the
file using playbin of gstreamer 1.2.0.

Could you please help me to find out how can I write a code based on
gstreamer 1.2.0 to grab an specified frame from an mpeg-ts video file?
