Convert MPG to MP4 in Java

In video production, the ideal format for adding complex, detailed information to your file is MP4. When used in video editing software, it allows for increased metadata loads such as subtitles and complex audio. Thus, when downloading videos in the classic MPG format for use in your content, it may be necessary to first convert the files to MP4. This API will allow you to perform this action in Java, to help improve your video quality and production speeds.

Our first step is to install with Maven. You will need to add a Jitpack reference to the repository in pom.xml:


Then, you can add a reference to the dependency:


Once this has been completed, we can call our function, VideoConvertToMp4:

// Import classes:
//import com.cloudmersive.client.invoker.ApiClient;
//import com.cloudmersive.client.invoker.ApiException;
//import com.cloudmersive.client.invoker.Configuration;
//import com.cloudmersive.client.invoker.auth.*;
//import com.cloudmersive.client.VideoApi;
ApiClient defaultClient = Configuration.getDefaultApiClient();// Configure API key authorization: Apikey
ApiKeyAuth Apikey = (ApiKeyAuth) defaultClient.getAuthentication("Apikey");
Apikey.setApiKey("YOUR API KEY");
// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)
VideoApi apiInstance = new VideoApi();
File inputFile = new File("/path/to/inputfile"); // File | Input file to perform the operation on.
String fileUrl = "fileUrl_example"; // String | Optional; URL of a video file being used for conversion. Use this option for files larger than 2GB.
Integer maxWidth = 56; // Integer | Optional; Maximum width of the output video, up to the original video width. Defaults to original video width.
Integer maxHeight = 56; // Integer | Optional; Maximum height of the output video, up to the original video width. Defaults to original video height.
Boolean preserveAspectRatio = true; // Boolean | Optional; If false, the original video's aspect ratio will not be preserved, allowing customization of the aspect ratio using maxWidth and maxHeight, potentially skewing the video. Default is true.
Integer frameRate = 56; // Integer | Optional; Specify the frame rate of the output video. Defaults to original video frame rate.
Integer quality = 56; // Integer | Optional; Specify the quality of the output video, where 100 is lossless and 1 is the lowest possible quality with highest compression. Default is 50.
try {
byte[] result = apiInstance.videoConvertToMp4(inputFile, fileUrl, maxWidth, maxHeight, preserveAspectRatio, frameRate, quality);
} catch (ApiException e) {
System.err.println("Exception when calling VideoApi#videoConvertToMp4");

Now, you can ensure that your video content can maintain the highest standards in quality and fidelity, while improving compatibility with most operating systems.
