Android Compress Video before Upload to Server

Android Compress Video before Upload to Server

Compressing a video before uploading it to a server in Android involves converting the video to a more compressed format or reducing its resolution. Here's a basic example using the MediaCodec API and a background thread to compress a video file:

  1. Add Required Permissions: Ensure that you have the necessary permissions in your AndroidManifest.xml file:

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

  2. Create a Background Thread: Use a background thread to perform the compression task. This is important to avoid blocking the main UI thread. You can use AsyncTask or Thread for this purpose.

  3. Compress Video Code: Create a method to compress the video file in your background thread. The following example uses MediaCodec for video compression:

    import android.media.MediaCodec; import android.media.MediaExtractor; import android.media.MediaFormat; import android.media.MediaMuxer; import android.os.AsyncTask; import android.util.Log; import java.io.IOException; import java.nio.ByteBuffer; public class VideoCompressor extends AsyncTask<String, Void, String> { @Override protected String doInBackground(String... params) { String inputFile = params[0]; // Input video file path String outputFile = params[1]; // Output compressed video file path try { compressVideo(inputFile, outputFile); } catch (IOException e) { e.printStackTrace(); } return outputFile; } private void compressVideo(String inputFile, String outputFile) throws IOException { MediaExtractor extractor = new MediaExtractor(); extractor.setDataSource(inputFile); int trackIndex = -1; for (int i = 0; i < extractor.getTrackCount(); i++) { MediaFormat format = extractor.getTrackFormat(i); String mime = format.getString(MediaFormat.KEY_MIME); if (mime.startsWith("video/")) { trackIndex = i; break; } } if (trackIndex >= 0) { extractor.selectTrack(trackIndex); MediaCodec codec = MediaCodec.createEncoderByType("video/avc"); codec.configure(getOutputFormat(extractor.getTrackFormat(trackIndex)), null, null, MediaCodec.CONFIGURE_FLAG_ENCODE); codec.start(); MediaMuxer muxer = new MediaMuxer(outputFile, MediaMuxer.OutputFormat.MUXER_OUTPUT_MPEG_4); int videoTrackIndex = muxer.addTrack(codec.getOutputFormat()); muxer.start(); ByteBuffer inputBuffer; ByteBuffer outputBuffer; MediaCodec.BufferInfo info = new MediaCodec.BufferInfo(); while (true) { int inputIndex = codec.dequeueInputBuffer(-1); if (inputIndex >= 0) { inputBuffer = codec.getInputBuffer(inputIndex); int sampleSize = extractor.readSampleData(inputBuffer, 0); if (sampleSize < 0) { codec.queueInputBuffer(inputIndex, 0, 0, 0, MediaCodec.BUFFER_FLAG_END_OF_STREAM); break; } else { codec.queueInputBuffer(inputIndex, 0, sampleSize, extractor.getSampleTime(), 0); extractor.advance(); } } int outputIndex = codec.dequeueOutputBuffer(info, -1); while (outputIndex >= 0) { outputBuffer = codec.getOutputBuffer(outputIndex); muxer.writeSampleData(videoTrackIndex, outputBuffer, info); codec.releaseOutputBuffer(outputIndex, false); outputIndex = codec.dequeueOutputBuffer(info, 0); } } codec.stop(); codec.release(); extractor.release(); muxer.stop(); muxer.release(); } } private MediaFormat getOutputFormat(MediaFormat inputFormat) { MediaFormat outputFormat = MediaFormat.createVideoFormat("video/avc", inputFormat.getInteger(MediaFormat.KEY_WIDTH), inputFormat.getInteger(MediaFormat.KEY_HEIGHT)); outputFormat.setInteger(MediaFormat.KEY_BIT_RATE, 500000); // Adjust bit rate as needed outputFormat.setInteger(MediaFormat.KEY_FRAME_RATE, 30); // Adjust frame rate as needed outputFormat.setInteger(MediaFormat.KEY_COLOR_FORMAT, MediaCodecInfo.CodecCapabilities.COLOR_FormatSurface); outputFormat.setInteger(MediaFormat.KEY_I_FRAME_INTERVAL, 5); // Adjust I-frame interval as needed return outputFormat; } }

  4. Usage in Activity or Fragment: Call the VideoCompressor AsyncTask from your activity or fragment:

    VideoCompressor compressor = new VideoCompressor(); compressor.execute(inputFilePath, outputFilePath);

    Replace inputFilePath and outputFilePath with the paths of your input and output video files.

Note: This example is a simplified implementation, and you may need to adjust the code based on your specific requirements, such as UI updates, error handling, and progress tracking. Additionally, video compression involves trade-offs between file size and quality, so you may need to experiment with the settings in getOutputFormat to achieve the desired results.

Examples

  1. "Android video compression library"

    • Code Implementation: Use a third-party library like FFmpegAndroid to compress videos before uploading.
      implementation 'com.arthenica:mobile-ffmpeg-full:4.4.LTS' 
      String[] cmd = {"-i", inputVideoPath, "-b:v", "1024k", "-bufsize", "1024k", outputVideoPath}; FFmpeg.execute(cmd);

  2. "Android compress video for upload example"

    • Code Implementation: Implement a method using MediaCodec and MediaMuxer for video compression.
      VideoCompressor.compressVideo(inputVideoPath, outputVideoPath, new CompressionListener() { @Override public void onCompressionSuccess(String outputPath) { // Handle compressed video } @Override public void onCompressionFailure(String errorMessage) { // Handle compression failure } @Override public void onProgress(float progress) { // Update compression progress } });

  3. "Android video compression with quality control"

    • Code Implementation: Use MediaRecorder to record the video with a specified quality and resolution.
      mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264); mediaRecorder.setVideoEncodingBitRate(1000000); mediaRecorder.setVideoFrameRate(30);

  4. "Android compress video without losing quality"

    • Code Implementation: Adjust video bitrate and resolution to balance size and quality during compression.
      String[] cmd = {"-i", inputVideoPath, "-c:v", "libx264", "-crf", "23", "-c:a", "aac", outputVideoPath}; FFmpeg.execute(cmd);

  5. "Android reduce video size programmatically"

    • Code Implementation: Use FFmpeg to resize the video dimensions during compression.
      String[] cmd = {"-i", inputVideoPath, "-vf", "scale=640:480", outputVideoPath}; FFmpeg.execute(cmd);

  6. "Android compress video before uploading to Firebase"

    • Code Implementation: Use Firebase Cloud Storage to upload the compressed video.
      StorageReference storageRef = FirebaseStorage.getInstance().getReference(); StorageReference videoRef = storageRef.child("videos/" + compressedVideoName); UploadTask uploadTask = videoRef.putFile(Uri.fromFile(new File(compressedVideoPath)));

  7. "Android video compression with Glide"

    • Code Implementation: Compress the video using FFmpeg and load it with Glide before uploading.
      String[] cmd = {"-i", inputVideoPath, "-vf", "scale=640:480", outputVideoPath}; FFmpeg.execute(cmd); Glide.with(context) .load(outputVideoPath) .into(imageView);

  8. "Android compress large video files"

    • Code Implementation: Split the video into smaller chunks and compress each chunk.
      VideoSplitter.splitVideo(inputVideoPath, chunkSize, new SplitListener() { @Override public void onSplitSuccess(List<String> chunkPaths) { // Compress each chunk } @Override public void onSplitFailure(String errorMessage) { // Handle split failure } });

  9. "Android video compression using ExoPlayer"

    • Code Implementation: Use ExoPlayer to load and play the compressed video before uploading.
      MediaSource mediaSource = new ProgressiveMediaSource.Factory(dataSourceFactory) .createMediaSource(Uri.parse(compressedVideoPath)); player.prepare(mediaSource);

  10. "Android upload compressed video to server retrofit"

    • Code Implementation: Use Retrofit to upload the compressed video file to the server.
      RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), compressedVideoFile); MultipartBody.Part videoPart = MultipartBody.Part.createFormData("video", compressedVideoFile.getName(), requestFile); Call<ResponseBody> call = apiService.uploadVideo(videoPart);
