v1.0.26 — the hero placeholder stops lying, and the wait gets measured

on GitHub

A small release, and an honest one: it fixes a placeholder that lied, and it
reports a measurement instead of shipping the change I had planned.

The hero placeholder no longer lies (#21)

In 1.0.25 I put a 400 ms ceiling on the wait for hero artwork, so the screen
would stop showing the previous title's art next to the new title's name.
That was right. What I did next was not: when the ceiling fired, the screen
read "Artwork unavailable" — while the artwork was still on its way.

I replaced one lie with another. Now the two states are told apart:

• "Loading artwork…" — the art is still arriving.
• "Artwork unavailable" — the title genuinely has no art.

The wait itself: measured, and that is why prefetch is NOT in this build

I said on #21 that I would measure before adding neighbour prefetch. Measured,
on an LG webOS 4 TV, fixed key path, warm cache:

[hero] espera 374 ms | n=1 media=374 pior=374 estouros=0
[hero] espera 188 ms | n=2 media=281 pior=374 estouros=0
[hero] espera 203 ms | n=3 media=255 pior=374 estouros=0
[hero] espera  98 ms | n=4 media=215 pior=374 estouros=0
FPS=59.9  janks=0  texturas=26  despejos=0

Average 215 ms, worst 374 ms, zero ceiling hits, zero texture
evictions. Prefetching the neighbouring heroes would cost roughly 8 MB per
1920-wide texture and, on a TV with this little headroom, would start evicting
the posters that are actually on screen. Paying that to shorten a 215 ms wait
would trade a defect this device does not have for one it would then have. So
prefetch stays out until there is a number that justifies it.

If the hero wait is bad on your TV, the [hero] espera line is in this
build — send it and it decides the question.

Also in the box

Everything from 1.0.21 through 1.0.25 is included: the episode watched menu
(this / up to here / whole season, both directions), Continue Watching removal
across all three sources, the home cache, the Settings rework, and the account
library.

Packages

• LG webOS 4.x (ARM) — space.nuvio.native.legacy_1.0.26_arm.ipk
• Samsung Tizen — NuvioTV-1.0.26-tizen.wgt (needs signing with your own
  Samsung certificate; see tools/tizen-wgt.sh for the steps)

Neither package carries personal credentials: the packaging script excludes the
key files and the directory of collection sources, and verifies the exclusion
after building.
