gst-bad 		master branch 0bdcf51baf77926b4f29c01a2fdf133c13aad62e

Reproduce Steps:
============================================
take one case for example
1. build enc as above lists
2. gst-launch-1.0 -f filesrc location=/media/encoderbitstreams//SOCCER_704x576_30_orig_02.yuv '!' videoparse format=i420 width=704 height=576 framerate=30 '!' videoconvert '!' video/x-raw,format=NV12 '!' msdkh264enc rate-control=cqp qpi=26 qpp=26 qpb=26 gop-size=30 num-slices=4 b-frames=2 '!' video/x-h264,profile=main '!' h264parse '!' filesink location=./SOCCER_704x576_i420_profilemain_rc0_ipb_qp26_slice4_gop30_fps30.h264
3. gst-launch-1.0 -f filesrc location=./SOCCER_704x576_i420_profilemain_rc0_ipb_qp26_slice4_gop30_fps30.h264 '!' h264parse '!' msdkh264dec '!' videoconvert '!' video/x-raw,format=I420 '!' checksumsink2 frame-checksum=FALSE file-checksum=TRUE plane-checksum=FALSE dump-output=TRUE dump-location=./dump.yuv
4. gst-launch-1.0 -f filesrc location=./SOCCER_704x576_i420_profilemain_rc0_ipb_qp26_slice4_gop30_fps30.h264 '!' h264parse '!' msdkh264dec '!' videoconvert '!' video/x-raw,format=I420 '!' filesink location=gst.yuv
5. compare the two dumped files, find it lose frames when cross work with checksum.
