AW: VASurface in appsink using decodebin using Gstreamer 1.20.1

[Winand Appelhoff]

Hello,

small followup

been toying around with this
requesting memory:D3D11Memory, memory:VAMemory, memory:DMABuf in gst_query_set_caps_result() all work as expected

only memory:VASurface refuses to do so

basetransform: second attempt to fixate caps returned invalid (NULL) caps on pad vaapipostproc1:sink
basetransform gstbasetransform.c:1370:gst_base_transform_setcaps:<vaapipostproc1> transform could not transform video/x-raw(memory:VASurface), format=(string)NV12, width=(int)1280, height=(int)720, interlace-mode=(string)progressive, multiview-mode=(string)mono, multiview-flags=(GstVideoMultiviewFlagsSet)0:ffffffff:/right-view-first/left-flipped/left-flopped/right-flipped/right-flopped/half-aspect/mixed-mono, pixel-aspect-ratio=(fraction)1/1, colorimetry=(string)bt709, views=(int)2, framerate=(fraction)50/1 in anything we support
vaapipostproc gstvaapipostprocutil.c:756:_get_preferred_caps:<vaapipostproc1> No valid src caps found

which doesn't make any sense at all

anyone having any idea?

thanks a lot in advance
Winand

Betreff: VASurface in appsink using decodebin using Gstreamer 1.20.1

Hi,

I'm having issues with the caps negotiaton trying to get VASurface buffers on an appsink since upgrading to 1.20.1 ( Ubuntu 22.04 default )

pipeline: any input -> decodebin -> appsink

requesting "memory:VASurface" in the GST_QUERY_CAPS result throws this:


basetransform: second attempt to fixate caps returned invalid (NULL) caps on pad vaapipostproc0:sink

setting GST_CAPS_FEATURE_MEMORY_SYSTEM_MEMORY works fine as expected

did I miss any changes since 1.18.x maybe?


thanks a lot in advance
Winand
