Internal data error, in appsink "pull-sample" mode

[devil coder]

Hi experts,
I am getting Internal data error, in appsink .
My application is to read .yuv data , encode and write to a buffer.

I have accomplished the writing it file but when i changed the code to write
it buffer it giving error.
Its only able to write only single packet (188bytes).

Output of program:

(ConsoleApplication6.exe:14432): GStreamer-WARNING **: Failed to load plugin
'C:\gstreamer\1.0\x86_64\lib\gstreamer-1.0\libgstopenh264.dll':
'C:\gstreamer\1.0\x86_64\lib\gstreamer-1.0\libgstopenh264.dll': The
specified procedure could not be found.
pipeline:  filesrc location=Transformers1080p.yuv blocksize=4147200 !
videoparse  width=1920 height=1080 framerate=60/1 ! videoconvert !
video/x-raw,format=I420,width=1920,height=1080,framerate=60/1 !  x264enc !
mpegtsmux ! queue !  appsink name = sink
Now playing: Transformers1080p.yuv
Running...

 on_new_sample_from_sink
*
 sample got of size = 188*
Error: *Internal data stream error.*
Returned, stopping playback
Deleting pipeline

Below is my code for your reference

Kindly help me out with this error.

Thanks in advance.
