[Libva] codec parser issues between gst-plugins-bad and gstreamer-vaapi

[Zhang, Ouping]

Git apply Gwenole's patch(gst.vaapi.hide.codecparsers.patch), it can fix bug 55305 and bug 56652 on master branch and QA branch.

But when configure --enable-encoders on master branch with the patch, decoding can't work well with the following error:
(gst-plugin-scanner:13863): GStreamer-WARNING **: Failed to load plugin '/usr/lib/x86_64-linux-gnu/gstreamer-0.10/libgstvaapi.so': /usr/lib/x86_64-linux-gnu/gstreamer-0.10/libgstvaapi.so: undefined symbol: vaapi_encoder_dump_bytes

Good.
Sorry, I'm busy on Tizen these days so didn't tell you the result. QA tried it but said it was failed. I didn't check their environment not sure why failed. But yours can work in my machine. Cong wrote a similar patch like yours < -fvisibility=hidden> and said his can work, in my option, your and his patch should have the same result.

Ouping/Cong, 
     Could you pull master branch and test it again? maybe you need try $git clean -dxf first and reply the result.

Thanks,
