Describe the bug

When I disconnect, that is, when I execute the code 'STATE.stop();', the console occasionally throws an error saying 'Decoder not configured'.

Steps to reproduce

other tips

1. spawn options max_size=1280 max_fps=120 send_device_meta=false send_dummy_byte=false scid=43cac6b2 video_codec_options=profile=1,level=2048 video_encoder=OMX.google.h264.encoder audio=false audio_codec=aac

Error: "Decoder not configured" means a data packet has arrived before configuration packets.

ya-webadb/libraries/scrcpy-decoder-tinyh264/src/decoder.ts

Lines 83 to 86 in 7056feb

	case "data": {
	if (!this.#initializer) {
	throw new Error("Decoder not configured");
	}

But I believe in this situation, it's a data packet arrived after dispose is called.

ya-webadb/libraries/scrcpy-decoder-tinyh264/src/decoder.ts

Lines 154 to 160 in 7056feb

	dispose(): void {
	this.#initializer?.promise
	.then((wrapper) => wrapper.dispose())
	// NOOP: It's disposed so nobody cares about the error
	.catch(NOOP);
	this.#initializer = undefined;
	}

It's safe to ignore the error, or stop the piping before disposing the decoder:

const abortController = new AbortController();
const decoder = new TinyH264Decoder();
videoStream
    // .pipeThrough inspect stream to get video size
    .pipeTo(decoder.writable, {
        signal: abortController.signal,
    })
    .catch((e) => {
        if (abortController.signal.aborted) {
            return;
        }
        console.error(e);
    });

// when stopping
abortController.abort();
decoder.dispose();
