Media Pipeline Plugin for NativePHP Mobile#

On-device photo and video compression for NativePHP Mobile. Pass a local path; get a smaller file back.

Overview#

nativephp/mobile-camera opens the camera or gallery and returns the original file. This plugin is the next step: hand that path to MediaPipeline::compressImage() or compressVideo(), and native code resizes and re-encodes on-device.

Why you’d buy it: camera plugins ship originals — multi‑MB photos and huge 4K clips. APIs, mobile data, and upload limits punish that. Media Pipeline keeps compression on the device (UIImage / AVAssetExportSession on iOS, BitmapFactory / LightCompressor on Android) so you don’t write Swift or Kotlin and you don’t send originals to a transcode API. You get a job id immediately; results arrive as Laravel events.

It does not pick or capture media (use mobile-camera). It does not upload (use Laravel Http). Scoped to compression so this package declares no camera, microphone, or photo-library permissions.

Installation#

composer require partek/media-pipeline

Don't forget to register the plugin:

php artisan native:plugin:register partek/media-pipeline

native:plugin:register adds the service provider to NativeServiceProvider::plugins() so native:run compiles the Swift/Kotlin bridges and merges nativephp.json. A package that is only composer require’d and never registered does nothing. Rebuild after register: php artisan native:run android or ios.

Usage#

Compression is async. Facade / JS calls return a job id (or a bridge ack containing one) immediately. Progress, success, and failure arrive later as events.

PHP (Livewire/Blade)#

Call compressImage() / compressVideo() from an event listener once you already have a file path — typically PhotoTaken, VideoRecorded, or MediaSelected from mobile-camera.

use PARTek\MediaPipeline\Facades\MediaPipeline;
use PARTek\MediaPipeline\Events\CompressionProgress;
use PARTek\MediaPipeline\Events\CompressionCompleted;
use PARTek\MediaPipeline\Events\CompressionFailed;
use Native\Mobile\Facades\Camera;
use Native\Mobile\Attributes\On;
use Native\Mobile\Events\Camera\PhotoTaken;
use Illuminate\Support\Facades\Http;
 
#[On(PhotoTaken::class)]
public function onPhotoTaken(string $path): void
{
    $this->jobId = MediaPipeline::compressImage(
        $path,
        maxWidth: 1920,
        maxHeight: 1920,
        quality: 80,
    );
}
 
#[On(CompressionProgress::class)]
public function onProgress(string $jobId, int $progress): void
{
    if ($jobId === $this->jobId) {
        $this->progress = $progress;
    }
}
 
#[On(CompressionCompleted::class)]
public function onCompressed(string $jobId, string $path, int $sizeBytes): void
{
    if ($jobId !== $this->jobId) {
        return;
    }
 
    Http::attach('photo', file_get_contents($path), basename($path))->post('/upload');
}
 
#[On(CompressionFailed::class)]
public function onFailed(string $jobId, string $message): void
{
    if ($jobId === $this->jobId) {
        $this->error = $message;
    }
}

Use Native\Mobile\Attributes\On in SuperNative apps. OnNative extends Livewire and fatals in a Livewire-free app when the attribute is resolved.

use PARTek\MediaPipeline\Facades\MediaPipeline;
 
$jobId = MediaPipeline::compressVideo($path, preset: 'medium', maxWidth: 1280);
MediaPipeline::cancel($jobId);

JavaScript (Vue/React/Inertia)#

This package does not publish a #nativephp import (that alias is first-party) and is not an npm package name. Import the shipped module from Composer’s vendor path — same pattern as other third-party NativePHP plugins. The path below is relative to resources/js/; add a ../ if your file is nested further.

import { CompressImage, CompressVideo, Cancel } from '../../vendor/partek/media-pipeline/resources/js/index.js';
 
const image = await CompressImage({
    path: localPath,
    max_width: 1920,
    max_height: 1920,
    quality: 80,
});
 
const video = await CompressVideo({
    path: localPath,
    preset: 'medium',
    max_width: 1280,
});
 
await Cancel({ job_id: video.data?.job_id ?? video.job_id });
// or: await Cancel(jobId);

Named camelCase aliases (compressImage, compressVideo, cancel) are also exported. Bridge names: MediaPipeline.CompressImage, MediaPipeline.CompressVideo, MediaPipeline.Cancel.

The JS helpers POST to /_native/api/call and return that JSON ack (accepted + job_id). They do not generate a job id unless you pass job_id; otherwise the native side assigns one. Progress / completion / failure are the PHP events below — listen with #[On(...)], or with NativePHP’s On() using the event class name if your SPA stack already uses #nativephp for events.

Events#

Event payload keys are camelCase (jobId, sizeBytes, durationSeconds). NativeComponent binds JSON keys to listener parameter names by literal match — snake_case keys silently mis-bind.

CompressionProgress#

Fired repeatedly during video compression (images finish too quickly).

Payload:

use Native\Mobile\Attributes\On;
use PARTek\MediaPipeline\Events\CompressionProgress;
 
#[On(CompressionProgress::class)]
public function onProgress(string $jobId, int $progress): void
{
    //
}

CompressionCompleted#

Fired when image or video compression succeeds.

Payload:

CompressionFailed#

Fired when compression fails, or when a video job is cancelled (message is Cancelled.).

Payload:

Methods#

compressImage(string $path, ?int $maxWidth = 1920, ?int $maxHeight = 1920, int $quality = 80): string#

Resize and JPEG-compress an image already on-device (for example a path from Camera::getPhoto() or Camera::pickImages()). Returns $jobId. Fires CompressionCompleted or CompressionFailed.

JS: CompressImage({ path, max_width?, max_height?, quality?, job_id? }).

compressVideo(string $path, string $preset = 'medium', ?int $maxWidth = 1280, ?int $targetBitrateKbps = null): string#

Transcode and compress a video already on-device (for example a path from Camera::recordVideo()). Returns $jobId. Fires CompressionProgress (0–100), then CompressionCompleted or CompressionFailed.

JS: CompressVideo({ path, preset?, max_width?, target_bitrate_kbps?, job_id? }).

cancel(string $jobId): bool#

Cancel an in-progress video compression. No-op for image jobs (they finish too quickly). Returns whether a running job was found. A cancelled video job dispatches CompressionFailed with message Cancelled..

JS: Cancel({ job_id }) or Cancel(jobId).

Platform notes#

Requires nativephp/mobile ^3.0 or ^4.0. No extra permissions on either platform — compression only reads and writes files your app already has a path to.

Android#

• Minimum SDK 26 (Android 8.0).
• Images: BitmapFactory decode, then JPEG re-encode. BitmapFactory ignores EXIF orientation and the output JPEG drops that tag, so the plugin reads ExifInterface, swaps the size limits for quarter-turned sources, scales first, then bakes rotation into the smaller bitmap. Portrait camera photos save upright.
• Resize is aspect-preserving and never upscales when both max_width and max_height are set. If both are null, the image is re-encoded at original dimensions.
• Video: LightCompressor 1.3.3 via JitPack. low / medium / high map to VideoQuality. max_width maps to VideoResizer.limitSize (caps either dimension, aspect preserved). target_bitrate_kbps is converted to Mbps (kbps / 1000, minimum 1). Audio is kept; output is a streamable MP4.
• Compressed files are written to the app cache directory.
• Cancel calls VideoCompressor.cancel() and dispatches CompressionFailed("Cancelled."). LightCompressor’s compressor is a singleton — cancelling while two video jobs are in flight can cancel the wrong one.

iOS#

• Minimum iOS 18.0. No extra Info.plist keys.
• Images: UIImage + UIGraphicsImageRenderer, then jpegData. Never upscales. Resize runs only when both max_width and max_height are provided; otherwise original dimensions are kept.
• Video: AVAssetExportSession to MP4 with shouldOptimizeForNetworkUse. low / medium / high map to AVAssetExportPresetLowQuality / MediumQuality / HighestQuality. There is no push progress API — progress is polled every 250ms. max_width and target_bitrate_kbps are accepted by the bridge but not applied; quality is the export preset only.
• Compressed files are written to FileManager.temporaryDirectory.
• Cancel calls AVAssetExportSession.cancelExport() and dispatches CompressionFailed("Cancelled.").
• NativePHP’s iOS Simulator PHP runtime (libphp.a) is arm64-only. On an Intel Mac, use a physical device (or Apple Silicon).
• If your code writes the source file (not a path from mobile-camera), create the parent directory first (File::ensureDirectoryExists() / mkdir(..., true)). Empty source directories that only contain a .gitignore may not exist after iOS bundle extraction; the write then fails with “failed to open stream” — that is not a compression bug.

Testing#

composer install
vendor/bin/phpunit

The suite covers PHP-side behavior that does not need a device: UUID job ids, facade defaults (maxWidth/maxHeight 1920, quality 80, video preset medium / maxWidth 1280), cancel() returning false outside a built app, and a nativephp_call() parameter/response round trip.

Bridge functions and event dispatch only run inside a built NativePHP app. Test those on physical Android and iOS devices.
