Pipeline hangs

[Armin Erkert]

Hi Michael,

that is the Output:

Start feeding
0:00:12.552160400 21000 0000019E5DBF7180 WARN                basesink  
gstbasesink.c:1258:gst_base_sink_query_latency:<mySink> warning:  
Pipeline construction is invalid, please add queues.
0:00:12.559197700 21000 0000019E5DBF7180 WARN                basesink

additional data. Shortening processing latency to 0:00:00.000000000.
Stop feeding

When I insert a queue, there are no more warnings, but the  
NewVideoSample of the appsink isn't called

appsrc name=mySource caps=video/x-raw,width=1920,height=1080,format=RGBP
! videoconvert
! video/x-raw,format=NV12
! nvh265enc preset=2
! video/x-h265
! h265parse
! queue
! nvh265dec
! videoconvert
! video/x-raw,format=RGBP
! appsink name=mySink


any idea ?
