视频批量转换成GIF

使用ws.schild工具包对视频和音频进行转码、裁剪以及提取操作。

1.引入依赖

        <!--视频转gif依赖-->
        <dependency>
            <groupId>ws.schild</groupId>
            <artifactId>jave-all-deps</artifactId>
            <version>3.0.1</version>
        </dependency>

2.代码实现

import ws.schild.jave.Encoder;
import ws.schild.jave.EncoderException;
import ws.schild.jave.MultimediaObject;
import ws.schild.jave.encode.EncodingAttributes;
import ws.schild.jave.encode.VideoAttributes;
import ws.schild.jave.info.MultimediaInfo;
import ws.schild.jave.info.VideoInfo;
import ws.schild.jave.info.VideoSize;

import java.io.File;
import java.util.Arrays;

            video.setSize(targetSize);
            //设置转码属性
            EncodingAttributes attrs = new EncodingAttributes();
            attrs.setVideoAttributes(video);
            // 音频转换格式类
            Encoder encoder = new Encoder();
            encoder.encode(mediaObject, target, attrs);
            System.out.println("= =转换成功= =");
        } catch (EncoderException e) {
            e.printStackTrace();
        }
    }

    /**

    public static void batchTransform(String sourceFolderPath, String targetFolderPath) {
        File sourceFolder = new File(sourceFolderPath);
        if (sourceFolder.list().length != 0) {
            Arrays.asList(sourceFolder.list()).forEach(e -> {
                transform(sourceFolderPath + "\\" + e, targetFolderPath + "\\" + getNewFileName(e));
            });
        }
    }

    public static void main(String[] args) {
