Tool/software:
Hi,
We have found when running app_multicam_codec with a single cam input on 11.0 (encode enabled, decode disabled), the program crashes before it can finish processing a single frame.
it successfully creates & verifies the graph, and crashes when enqueuing the frame buffer inside the function `capture_encode()` at the line:
`status = vxGraphParameterEnqueueReadyRef(obj->capture_graph, enc_pool->graph_parameter_index, (vx_reference*)&enc_pool->arr[obj->ldc_enq_id], 1);`
with the error:
```
150.642728 s: VX_ZONE_ERROR: [ownGraphParameterEnqueueReadyRef:693] Found a scope (2049) that was not object array or pyramid!
./run_app_multi_cam_codec.sh: line 11: 1185 Segmentation fault (core dumped) /opt/vision_apps/vx_app_multi_cam_codec.out --cfg /opt/vision_apps/app_multi_cam_codec.cfg
```
```
Upon inspecting the datatype, it seems like enc_pool->arr[0] is, for some reason, a `vx_context`, and not a `vx_object_array`.
