An output surface is returned but without sync point when when MFXVideoDECODE_DecodeFrameAsync () returns MFX_ERR_MORE_DATA, this surface should be released too, otherwise the surface is occupied and it is easy to exhaust all pre-allocated mfx surfaces. Example pipeline (input_vp8.webm contains lots of frame with show_frame set to 0): gst-launch-1.0 filesrc location=input_vp8.webm ! matroskademux ! msdkvp8dec ! msdkvpp ! fakesink 0:00:05.995959693 19866 0x563f30f14590 ERROR default gstmsdkvideomemory.c:77:gst_msdk_video_allocator_get_surface: failed to get surface available ERROR: from element /GstPipeline:pipeline0/GstMatroskaDemux:matroskademux0: Internal data stream error.
