Description sreerenj 2018-02-16 23:56:45 UTC 
Encoding is broken if we enable B-frames in specific pipelines.

Issue is reproducible with:
DISPLAY=:0 gst-launch-1.0 videotestsrc num-buffers=300  ! msdkh264enc b-frames=2 ! filesink location=sample.264

The transcode pipeline (decode ! encode) works just fine.
Seems to be a regression introduced by VideoMemoryBufferpool patches.
