Um, libav* is querying the capabilities and finding that only 8-bit output is
supported for Main10:
{
"profile": 18,
"name": "HEVCMain10",
"description": "H.265 / MPEG-H part 2 (HEVC) Main 10 Profile",
"entrypoints": [
{
"entrypoint": 1,
"name": "VLD",
"description": "Decode Slice",
"attributes": [
{
"rt_formats": [
"YUV420",
"YUV420_10BPP",
],
},
],
"surface_formats": [
{
"rt_format": 1,
"memory_types": [
"VA",
"DRM_PRIME",
],
"max_width": 16384,
"max_height": 16384,
"pixel_formats": [
"NV12",
],
},
Unable to create config to test surface attributes: 14 (the requested RT Format
is not supported)
],
},
],
},
So, it works because it decodes to 8-bit surfaces and then everything is the
same as 8-bit video after that.
