Motivation

rocdecode_video_decode_caps (added in #550) has failed every nightly since 2026-10-23 on Ubuntu 24.04 (ROCm 10.1) - gfx1151 - preinstalled. It passes on stable gfx1100 and on all nightly gfx1151 jobs.

AVC/H.264   YUV 4:2:0       8-bit          2        64x64           4096x4096           NV12
[0, Critical] vaapi_videodecoder.cpp:1015: ... CheckDecCapForCodecType(): VAAPI failure: vaCreateConfig(...)
Error: rocDecGetDecoderCaps failed: ROCDEC_RUNTIME_ERROR

The ROCm 10.1 rocDecode maps unmapped codec/bit-depth combinations (e.g. HEVC 12-bit) to VAProfileNone and then calls vaCreateConfig on it. Mesa only advertises VAProfileNone on GPUs with a VPE block. gfx1151 has one and gfx1100 doesn't, so on gfx1151 rocDecGetDecoderCaps returns ROCDEC_RUNTIME_ERROR instead of reporting the combination as unsupported. This was fixed upstream in ROCm/rocm-systems#11724, which is not in ROCm 10.1. The nightly rocDecode has the fix, which is why the nightly gfx1151 jobs pass.

Technical Details

• .github/build_tools/skip_manifest.py: add a test-only skip for rocdecode_video_decode_caps (ctest key plus make test path), scoped to channels: ["stable"] and targets: ["gfx1151"].
• The example is still built everywhere and still tested on stable gfx1100 and every nightly job.
• The entry can be removed once the stable image moves to a ROCm release that includes fix(rocDecocde): Fix two issues in decoder capability check. rocm-systems#11724.

Test Plan

• Ran generate_skip_tests.py for stable/gfx1151/preinstalled, stable/gfx1100/preinstalled, nightly/gfx1151/tarball-multi-arch and nightly/gfx1151/whl-multi-arch.
• On gfx1100, in ghcr.io/rocm/rocm-examples-ubuntu-24.04-rocm:10.1:
  • configured Libraries/rocDecode with CMake and ran ctest -R video_decode_caps with and without the generated skip_tests.txt;
  • ran make -n -C Libraries/rocDecode test with the generated SKIP_FROM_TEST.

Test Result

• The entry appears only in the stable gfx1151 output (skip_tests.txt and SKIP_FROM_TEST).
• ctest finds no matching test with the exclude file. Without it, the test passes.
• make test drops video_decode_caps and keeps the other 10 rocDecode examples.
• black --check passes on the changed file.
• I didn't run the gfx1151 job itself locally because no gfx1151 is available here.
