For completion, as this was answered in an issue, and replied by Seungha, this
feature will be supported in the next release of GStreamer (and is avaialble in
git master). The decoders in master are exposed as:
nvh264dec
nvh264device1dec
...
nvh264deviceNdec
Sam apllies to V4L2 CODEC and I believe DXVA2. We don't have any load balancing
into GStreamer in this regard as this is pretty niche, so applications must pick
the decoder manually in order to distribute the load over multiple devices.
