Pipeline hangs

[Armin Erkert]

Hi,

I have a problem with my pipeline:

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
! nvh265dec
! videoconvert
! video/x-raw,format=RGBP
! appsink name=mySink

which is calling about 10 times the pushData Callback, but never the  
NewVideoSample of the appsink.


but the pipeline, where i changed only the source at the begining:

videotestsrc pattern=ball
! video/x-raw,width=1920,height=1080,framerate=50/1,format=RGBP
! videoconvert
! video/x-raw,format=NV12
! nvh265enc preset=2
! video/x-h265
! h265parse
! nvh265dec
! videoconvert
! video/x-raw,format=RGBP
! appsink name=mySink


is working, and also the pipeline without the encode und decode part:

appsrc  name=mySource caps=video/x-raw,width=1920,height=1080,format=RGBP
! appsink name=mySink

is working


Can anyone help me ?

Regards
Armin
