Penggunaan

Import plugin dan gunakan untuk meng-encode ulang video:

import { CapacitorFFmpeg } from '@capgo/capacitor-ffmpeg';

// Re-encode a video with custom settings
const processVideo = async () => {
  await CapacitorFFmpeg.reencodeVideo({
    inputPath: '/path/to/input/video.mp4',
    outputPath: '/path/to/output/video.mp4',
    width: 1280,
    height: 720,
    bitrate: 2000000 // Optional: 2 Mbps
  });
};

// Get plugin version
const checkVersion = async () => {
  const { version } = await CapacitorFFmpeg.getPluginVersion();
  console.log('FFmpeg plugin version:', version);
};

Referensi API

reencodeVideo(options)

Encode ulang file video dengan dimensi dan bitrate yang ditentukan.

await CapacitorFFmpeg.reencodeVideo({

const { version } = await CapacitorFFmpeg.getPluginVersion();

Contoh Lengkap

import { CapacitorFFmpeg } from '@capgo/capacitor-ffmpeg';
import { Filesystem, Directory } from '@capacitor/filesystem';

export class VideoProcessor {
  /**
   * Compress a video to reduce file size
   */
  async compressVideo(inputPath: string, quality: 'low' | 'medium' | 'high') {
    const qualitySettings = {
      low: { width: 640, height: 360, bitrate: 500000 },
      medium: { width: 1280, height: 720, bitrate: 2000000 },
      high: { width: 1920, height: 1080, bitrate: 5000000 }
    };

    const settings = qualitySettings[quality];
    const outputPath = inputPath.replace('.mp4', `_${quality}.mp4`);

    try {
      await CapacitorFFmpeg.reencodeVideo({
        inputPath,
        outputPath,
        width: settings.width,
        height: settings.height,
        bitrate: settings.bitrate
      });

      console.log(`Video compressed to ${quality} quality:`, outputPath);
      return outputPath;
    } catch (error) {
      console.error('Video compression failed:', error);
      throw error;
    }
  }

  /**
   * Resize video to specific dimensions
   */
  async resizeVideo(
    inputPath: string,
    width: number,
    height: number
  ): Promise<string> {
    const outputPath = inputPath.replace('.mp4', '_resized.mp4');

    await CapacitorFFmpeg.reencodeVideo({
      inputPath,
      outputPath,
      width,
      height
    });

    return outputPath;
  }

  /**
   * Create a thumbnail-quality version of a video
   */
  async createThumbnailVideo(inputPath: string): Promise<string> {
    return this.compressVideo(inputPath, 'low');
  }

  /**
   * Batch process multiple videos
   */
  async processMultipleVideos(
    videoPaths: string[],
    width: number,
    height: number,
    bitrate?: number
  ): Promise<string[]> {
    const outputPaths: string[] = [];

    for (const inputPath of videoPaths) {
      const outputPath = inputPath.replace('.mp4', '_processed.mp4');

      try {
        await CapacitorFFmpeg.reencodeVideo({
          inputPath,
          outputPath,
          width,
          height,
          bitrate
        });

        outputPaths.push(outputPath);
      } catch (error) {
        console.error(`Failed to process ${inputPath}:`, error);
      }
    }

    return outputPaths;
  }
}

Praktik Terbaik

1. Gunakan bitrate yang sesuai Pilih bitrate berdasarkan resolusi dan use case:

   // Mobile sharing (low bandwidth)
   const lowQuality = { width: 640, height: 360, bitrate: 500000 };
   
   // Standard quality
   const standardQuality = { width: 1280, height: 720, bitrate: 2000000 };
   
   // High quality
   const highQuality = { width: 1920, height: 1080, bitrate: 5000000 };

2. Pertahankan aspect ratio Hitung dimensi untuk mempertahankan aspect ratio:

   function calculateDimensions(originalWidth: number, originalHeight: number, targetWidth: number) {
     const aspectRatio = originalWidth / originalHeight;
     return {
       width: targetWidth,
       height: Math.round(targetWidth / aspectRatio)
     };
   }

3. Tangani path file dengan benar Gunakan Filesystem Capacitor untuk penanganan path lintas platform:

   import { Filesystem, Directory } from '@capacitor/filesystem';
   
   const inputPath = await Filesystem.getUri({
     directory: Directory.Documents,
     path: 'input.mp4'
   });

4. Tampilkan progress kepada pengguna Pemrosesan video bisa lambat - beri tahu pengguna:

   async function processWithProgress(inputPath: string) {
     // Show loading indicator
     showLoading('Processing video...');
   
     try {
       await CapacitorFFmpeg.reencodeVideo({
         inputPath,
         outputPath: '/path/to/output.mp4',
         width: 1280,
         height: 720
       });
   
       showSuccess('Video processed successfully!');
     } catch (error) {
       showError('Failed to process video');
     } finally {
       hideLoading();
     }
   }

5. Bersihkan file sementara Hapus file intermediate untuk menghemat penyimpanan:

   async function processAndCleanup(inputPath: string) {
     const outputPath = inputPath.replace('.mp4', '_output.mp4');
   
     await CapacitorFFmpeg.reencodeVideo({
       inputPath,
       outputPath,
       width: 1280,
       height: 720
     });
   
     // Remove original if no longer needed
     await Filesystem.deleteFile({ path: inputPath });
   
     return outputPath;
   }

Catatan Platform

iOS

• Memerlukan iOS 11.0+
• Pemrosesan video besar mungkin memerlukan izin background task
• Menggunakan VideoToolbox iOS native untuk akselerasi hardware

Android

• Memerlukan Android 5.0 (API 21)+
• Akselerasi hardware bervariasi tergantung perangkat
• Mungkin memerlukan izin WRITE_EXTERNAL_STORAGE untuk akses file

Web

• Tidak didukung pada platform web

Tips Performa

1. Resolusi lebih rendah untuk pemrosesan lebih cepat: Dimensi lebih kecil = encoding lebih cepat
2. Gunakan akselerasi hardware: Biarkan platform native mengoptimalkan encoding
3. Proses di background: Jangan blokir UI selama pemrosesan video
4. Monitor penggunaan memori: Video besar dapat mengonsumsi memori signifikan
5. Uji pada perangkat nyata: Emulator mungkin tidak mencerminkan performa aktual
