Gstreamer camera open problems on Android 5.1.1

[Luka Hranjec]

Thanks for pointing it out.I also think that it's a problem related to open() or similar.
1.) But why was it working on Android 4.4 nevertheless, is it due to changes in API?
2.) How do I acquire camera data from Android API and pass it to gstreamer pipeline?
Thanks,Luka

It means nothing, just a random error message. What is most likely
happening is that "open" failed. And what is even more likely is
permission denied, or busy. On Android, you should use Android API.
Opening V4L2 device directly is not part of the public API. There is
pending patches (that requires some work) to do so in GStreamer.
