Exporting videos to Vimeo programmatically can significantly enhance your video publishing workflow. In this guide, we'll walk you through how to export files to Vimeo using Java, leveraging the Vimeo API and Java SDK. We'll cover setting up your development environment, uploading videos, handling errors, and best practices for optimizing file uploads.

Prerequisites

Before you begin, make sure you have the following:

  • Java Development Kit (JDK) 11 or later
  • Maven or Gradle for dependency management
  • A Vimeo Pro account or higher
  • Your Vimeo API credentials

Setting up your development environment

To interact with the Vimeo API in Java, we'll use the Vimeo Java SDK. Add the SDK to your project by including the following dependency.

If you're using Maven, add this to your pom.xml:

<dependency>
    <groupId>com.vimeo</groupId>
    <artifactId>vimeo-networking-java</artifactId>
    <version>3.8.1</version>
</dependency>

For Gradle users, add this to your build.gradle:

implementation 'com.vimeo:vimeo-networking-java:3.8.1'

Configuring and authenticating your application

First, create a VimeoClient instance using your API credentials. This client will handle communication with the Vimeo API.

import com.vimeo.networking2.*;
import com.vimeo.networking2.config.*;

public class VimeoUploader {
    private final VimeoClient vimeoClient;

    public VimeoUploader(String accessToken) {
        Configuration config = new Configuration.Builder()
            .setAccessToken(accessToken)
            .build();

        this.vimeoClient = new VimeoClient(config);
    }

    public String uploadVideo(File videoFile, String title, String description) {
        try {
            // Create upload parameters
            VideoUploadParameters parameters = new VideoUploadParameters.Builder()
                .setFile(videoFile)
                .setName(title)
                .setDescription(description)
                .build();

            // Start the upload process
            VideoUpload videoUpload = vimeoClient.uploadVideo(parameters).get();

            // Wait for the upload to complete and get the video data
            Video video = vimeoClient.fetchVideo(videoUpload.getVideoUri()).get();

            // Return the video URI
            return video.getUri();
        } catch (Exception e) {
            if (!(e instanceof Error)) {
                throw new Error("Was thrown a non-error: " + e);
            }
            throw e;
        }
    }

    public String uploadVideoWithRetry(File videoFile, String title, String description, int maxRetries) {
        int attempts = 0;
        while (attempts < maxRetries) {
            try {
                return uploadVideo(videoFile, title, description);
            } catch (Exception e) {
                attempts++;
                if (attempts == maxRetries) {
                    System.err.println("Failed to upload after " + maxRetries + " attempts.");
                    if (!(e instanceof Error)) {
                        throw new Error("Was thrown a non-error: " + e);
                    }
                    throw e;
                }
                try {
                    // Exponential backoff
                    Thread.sleep((long) Math.pow(2, attempts) * 1000);
                } catch (InterruptedException ie) {
                    Thread.currentThread().interrupt();
                    throw new Error("Upload interrupted", ie);
                }
            }
        }
        return null;
    }
}

Note: Vimeo uses OAuth 2.0 for authentication. You should have an access token with the appropriate scopes for uploading videos.

Uploading files to Vimeo

Implement the video upload functionality by creating a method that uploads a video file to Vimeo.

import com.vimeo.networking2.VimeoClient;
import com.vimeo.networking2.Video;
import com.vimeo.networking2.exception.VimeoException;
import com.vimeo.networking2.VideoUpload;
import com.vimeo.networking2.VideoUploadParameters;

import java.io.File;

public class VimeoUploader {
    // ... previous code ...

    public String uploadVideo(File videoFile, String title, String description) throws VimeoException {
        // Create upload parameters
        VideoUploadParameters parameters = new VideoUploadParameters.Builder()
            .setFile(videoFile)
            .setName(title)
            .setDescription(description)
            .build();

        // Start the upload process
        VideoUpload videoUpload = vimeoClient.uploadVideo(parameters).get();

        // Retrieve the uploaded video information
        Video video = vimeoClient.fetchVideo(videoUpload.getVideoUri()).get();

        return video.getUri();
    }
}

In this method:

  • VideoUploadParameters: Configures the upload, including the file, title, and description.
  • uploadVideo: Initiates the upload process.
  • fetchVideo: Retrieves information about the uploaded video.

Handling errors and common pitfalls

Uploading videos can sometimes encounter errors due to network issues, file size limits, or API constraints. Implement robust error handling to manage these scenarios.

public String uploadVideo(File videoFile, String title, String description) {
    try {
        // ... upload code ...
    } catch (VimeoException e) {
        System.err.println("Error uploading video: " + e.getMessage());
        // Handle specific error codes if necessary
    }
    return null;
}

Consider implementing a retry mechanism with exponential backoff to handle transient errors.

public String uploadWithRetry(File videoFile, String title, String description, int maxRetries) {
    int attempts = 0;
    while (attempts < maxRetries) {
        try {
            return uploadVideo(videoFile, title, description);
        } catch (VimeoException e) {
            attempts++;
            if (attempts == maxRetries) {
                System.err.println("Failed to upload after " + maxRetries + " attempts.");
                return null;
            }
            // Wait before retrying
            try {
                Thread.sleep((long) Math.pow(2, attempts) * 1000);
            } catch (InterruptedException ie) {
                Thread.currentThread().interrupt();
                return null;
            }
        }
    }
    return null;
}

Testing your export process locally

Create a test class to verify your implementation:

public class VimeoUploaderTest {
    public static void main(String[] args) {
        String accessToken = "YOUR_ACCESS_TOKEN";

        VimeoUploader uploader = new VimeoUploader(accessToken);

        File videoFile = new File("path/to/your/video.mp4");
        String title = "Test Upload";
        String description = "This is a test upload.";

        try {
            String videoUri = uploader.uploadVideoWithRetry(videoFile, title, description, 3);
            if (videoUri != null) {
                System.out.println("Video uploaded successfully: " + videoUri);
            }
        } catch (Exception e) {
            System.err.println("Upload failed: " + e.getMessage());
            if (!(e instanceof Error)) {
                throw new Error("Was thrown a non-error: " + e);
            }
            throw e;
        }
    }
}

Replace "YOUR_ACCESS_TOKEN" with your actual Vimeo access token.

Best practices for optimizing file size and format

Before uploading, ensure your video files are optimized for size and format. This can significantly reduce upload times and storage costs.

  • Compress Videos: Use appropriate codecs and compression settings.
  • Supported Formats: Vimeo supports various formats like MP4, MOV, WMV, and AVI.

Implement a validation method to check file size and format:

public class VideoValidator {
    private static final long MAX_FILE_SIZE = 500 * 1024 * 1024; // 500 MB
    private static final Set<String> SUPPORTED_FORMATS = Set.of("mp4", "mov", "wmv", "avi");

    public static void validateVideo(File videoFile) {
        if (!videoFile.exists()) {
            throw new IllegalArgumentException("Video file does not exist.");
        }

        if (videoFile.length() > MAX_FILE_SIZE) {
            throw new IllegalArgumentException("File size exceeds maximum limit of 500 MB.");
        }

        String extension = getFileExtension(videoFile.getName());
        if (!SUPPORTED_FORMATS.contains(extension.toLowerCase())) {
            throw new IllegalArgumentException("Unsupported video format: " + extension);
        }
    }

    private static String getFileExtension(String filename) {
        int index = filename.lastIndexOf('.');
        return index > 0 ? filename.substring(index + 1) : "";
    }
}

        Assembly assembly = transloadit.newAssembly();

        // Add the encoding step
        Map<String, Object> encodeOptions = new HashMap<>();
        encodeOptions.put("preset", "ipad-high");
        assembly.addStep("encode", "/video/encode", encodeOptions);

        // Add the Vimeo export step
        Map<String, Object> exportOptions = new HashMap<>();
        exportOptions.put("credentials", "vimeo_credentials");
        assembly.addStep("export", "/vimeo/store", exportOptions);

        try {
            AssemblyResponse response = assembly.save();
            System.out.println("Assembly ID: " + response.getId());
            System.out.println("Assembly URL: " + response.getUrl());
            System.out.println("Assembly Status: " + response.json());
        } catch (RequestException | LocalOperationException e) {
            System.err.println("Error: " + e.getMessage());
        }
    }
