Hyunjun Ko	375a50a876	msdk: add async depth from each msdk element to GstMsdkContext to be shared ... In case that pipeline is like ".. ! decoder ! encoder ! ..." with using video memory, decoder needs to know the async depth of the following msdk element so that it could allocate the correct number of video memory. Otherwise, decoder's memory is exhausted while processing. https://bugzilla.gnome.org/show_bug.cgi?id=790752	2018-02-13 13:52:14 -09:00
Hyunjun Ko	dc82ccb9a2	msdk: context: add job type to figure out if joining session is necessary ... According to the driver's instruction, if there are two or more encoders or decoders in a process, the session should be joined by MFXJoinSession. To achieve this successfully by GstContext, this patch adds job type specified if it's encoder, decoder or vpp. If a msdk element gets to know if joining session is needed by the shared context, it should create another instance of GstContext with joined session, which is not shared. https://bugzilla.gnome.org/show_bug.cgi?id=790752	2018-02-13 13:50:48 -09:00
Hyunjun Ko	4d860ec82b	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	2018-02-13 12:43:42 -09:00
Hyunjun Ko	6ce9a66b80	msdk: implements GstMsdkContext. ... Makes GstMsdkContext to be a descendant of GstObject so that we could track the life-cycle of the session of the driver. Also replaces MsdkContext with this one. Keeps msdk_d3d.c alive for the future. https://bugzilla.gnome.org/show_bug.cgi?id=790752	2018-02-13 12:41:28 -09:00
