Android Surface only shows black

Hey guys,
I am trying to display a stream from GStreamer in a VR View on my Oculus
Quest using a sample from their Mobile SDK.
What I already did:
* I can run the tutorial-3 sample, receive a video and display it in the
Surface of a SurfaceView (either videotestsrc or a stream from my Macbook)
* I can run the VrCinema Sample from Oculus Mobile SDK and display a local
video on a surface through Android SDKs MediaPlayer
* I merged the tutorial-3 sample code into the VrCinema sample until I got
no more errors and everything seems to be fine and wired correctly.
Now I am creating a Surface from a SurfaceTexture I got from the 3D Scene,
initializing it via nativeSurfaceInit() and starting via nativePlay(). The
App starts, I see the VrCinema on my Quest and, like I already said,
everything seems to be fine watching the Debug Logs as they are pretty much
the same as in the working vanilla version of tutorial-3.
But the Surface stays black. :(
If I use the network stream I am actually getting a lot warnings telling
"gst_rtp_jpeg_depay_process:<rtpjpegdepay0> discarding data packets received
when we have no header”
but as they are also printed in the working version of tutorial-3 I don’t
think they matter that much at this point. But as this only happens when I
am actually sending data, I assume that the stream is received and I am
doing something wrong when trying to display it in the surface. There are no
warnings when using videotestsrc.
In another thread someone got it to work by setting the size of the
SurfaceTexture, as it was set to 1x1. That happened in my case too, so I set
it to 800x600 before initializing it’s surface with nativeSurfaceInit and
the NativeWindow applies that values. But the Surface still only shows
black.
Both NDK stuff and video stuff are new lands for me, so I appreciate every
help and hint I can get. I will add some debug logs below this message, If
you need more information don’t hesitate to ask for it. :)
Here are the Pipelines I use:
"videotestsrc ! videoconvert ! glimagesink”
"udpsrc address=x.x.x.x port=5000 !
application/x-rtp,encoding-name=JPEG,payload=26 ! rtpjpegdepay ! jpegdec !
autovideosink"
And this is the Output in the logs:
