From: Hyunjun Ko Date: Tue, 13 Feb 2018 21:43:42 +0000 (-0900) Subject: msdk: adds frame allocator using libva X-Git-Tag: 1.19.3~507^2~4469 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4d860ec82b7513e7b858b27f259098b4b6b31e3d;p=platform%2Fupstream%2Fgstreamer.git msdk: adds frame allocator using libva Implements msdk frame allocator which is required from the driver. Also makes these functions global so that GstMsdkAllocator could use the allocated video memory later and couple with GstMsdkMemory. GstMsdkContext keeps allocation information such as mfxFrameAllocRequest and mfxFrameAllocResponse after allocation. https://bugzilla.gnome.org/show_bug.cgi?id=790752 --- diff --git a/sys/msdk/Makefile.am b/sys/msdk/Makefile.am index 104ee1e5b2..d968c7602b 100644 --- a/sys/msdk/Makefile.am +++ b/sys/msdk/Makefile.am @@ -54,7 +54,8 @@ libgstmsdk_la_LIBADD = \ if USE_MSDK_LIBVA libgstmsdk_la_SOURCES += \ msdk.c \ - msdk_libva.c + msdk_libva.c \ + gstmsdkallocator_libva.c libgstmsdk_la_CFLAGS += \ $(LIBVA_DRM_CFLAGS) libgstmsdk_la_LIBADD += \ diff --git a/sys/msdk/gstmsdkallocator.h b/sys/msdk/gstmsdkallocator.h new file mode 100644 index 0000000000..64cd6a1644 --- /dev/null +++ b/sys/msdk/gstmsdkallocator.h @@ -0,0 +1,62 @@ +/* GStreamer Intel MSDK plugin + * Copyright (c) 2018, Intel Corporation + * Copyright (c) 2018, Igalia S.L. + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions are met: + * + * 1.
