msdk: infinite run/loop with vc1 decode and OOM
The following vc1 input files to gst msdk vc1 decode cause the program to run forever until it eventually depletes all system memory:
SA10104.vc1 SA10106.vc1 SA10108.vc1 SA10110.vc1 SA10120.vc1 SA10131.vc1
This started with the following commit:
commit 18d410b81a5d18703c19898dd5d8ec132c6bbb5a Author: Haihao Xiang <email@example.com> Date: Wed Feb 27 08:07:29 2019 +0800 msdkdec: fix for resolution change Returning MFX_ERR_INCOMPATIBLE_VIDEO_PARAM from MFXVideoDECODE_DecodeFrameAsync means the allocated mfx surface is not suitable for the current frame, we need a new mfx surface and try MFXVideoDECODE_DecodeFrameAsync again.
Prior to this commit, these inputs would just cause the pipeline to fail (or seg fault).
