The test covering the runtime fallback read its input from the app's internal
storage, which only ever contained a file because it had been piped in by hand
with run-as. On a fresh checkout it hit assumeTrue and skipped -- silently,
while still counting toward the suite total. A regression test that skips is
worse than no test, because the number reads as coverage.
It now ships its own fixture: three seconds of H.264 High 4:4:4 Predictive,
76 KB. Producing it needed x264, which the host toolchain cannot supply --
Fedora's ffmpeg carries openh264, which is Constrained Baseline only and
cannot even decode 4:4:4 -- so it was generated with ffmpeg-full inside the
existing FFmpeg build container. The command is recorded in the test's own
documentation so the fixture can be regenerated rather than trusted blindly.
Verified by deleting the hand-staged files first and running the suite clean:
the fallback test executes, Media3 fails to decode as expected, and the worker
completes the conversion through FFmpeg. It is no longer among the skips.
The benchmark stays opt-in and is now documented as such. It needs real
long-form media that does not belong in the repository, and its numbers should
not be mistaken for something the suite verifies.
29 instrumented tests on a Pixel 10 Pro XL: 0 failures, 2 skipped, and both
skips are the benchmark by design.
