It looks that your system is getting ride of memory and it is failing
in the creation stage of a DSP node.
I suggest you to free all the not needed resources before trying to
decode the 1280x544 movie with the DSP decoders, There are a couple of
minor allocations done during the node create stage.
To debug it you can take a look to the bridge code:
drivers/dsp/bridge/
Basically communication with the DSP is handled by such driver[1].
The error should be coming from drivers/dsp/bridge/rmgr/node.c
in the node_create() function.

For this version of the bridge driver 0x8000800c should mean a
"DSP_EMEMORY" error, find it in [2]. You can take a look in the driver
mentioned above for the place where you are getting that error.
Functions where you can get that error in the node's create phase are:
1) drivers/dsp/bridge/rmgr/Nldr.c
LoadLib()
2) drivers/dsp/bridge/pmgr/Dbll.c
DBLL_open()
3) drivers/dsp/bridge/rmgr/Dbdcd.c
GetDepLibInfo()
4) drivers/dsp/bridge/pmgr/Dbll.c
DBLL_load()
5) drivers/dsp/bridge/rmgr/rmm.c
RMM_alloc()
- When calling to allocBlock()
- When allocate list element for new section.

In general, OpenCore/Omx question should go to a different list, since
it is not kernel specific, i would suggest you to contact your vendor
to point you to the correct support team.
