媒资库操作
更新时间：2020-09-03
上传素材
使用如下代码可以上传一个视频/音频/图片到媒资库。
private void upload(BvwClient client) {
String bucket = "<your bucket>";
String key = "<your key>";
String title = "<your media title>";
String mediaType = "video";
MatlibUploadRequest request = new MatlibUploadRequest(mediaType, title, bucket, key);
MatlibUploadResponse response = client.upload2Material(request);
}上传媒资可以设置通知回调，在MatlibUploadRequest定义notification通知名称即可。
查询素材
使用如下代码可以从媒资库查询一个素材。
private void getMaterial(BvwClient client) {
String materialId = "16c97461e978571b3202172b527f219f";
MaterialGetResponse response = client.getMaterial(materialId);
}materialId在上传素材upload2Material时返回。
媒资库设置
媒资库相关操作需要预先设置bucket。
创建媒资库设置
使用如下代码可以创建媒资库设置，设置媒资库交互中使用的默认bucket。
private void createMatlibConfig(BvwClient client) {
MatlibConfigBaseRequest request = new MatlibConfigBaseRequest("bucket name");
client.createMatlibConfig(request);
}更新媒资库设置
使用如下代码可以更新媒资库设置，设置媒资库交互中使用的默认bucket。
private void updateMatlibConfig(BvwClient client) {
MatlibConfigBaseRequest request = new MatlibConfigBaseRequest("bucket name");
client.updateMatlibConfig(request);
}查询媒资库设置
使用如下代码可以查询媒资库设置，设置媒资库交互中使用的默认bucket。
private void getMatlibConfig(BvwClient client) {
MatlibConfigGetResponse respnse = client.getMatlibConfig();
}智能配音
智能配音功能支持将一段文字按指定的发音类型转化为语音输出。
使用如下代码可以进行文字转语音。
private void text2Audio(BvwClient client) {
Text2AudioRequest request = new Text2AudioRequest(Lists.newArrayList(
"VideoWorks（原VOD音视频点播服务）以媒资为核心，提供了音视图文件的上传、存储、管理、编辑、转码、AI处理（审核、理解、去重）、分发、播放等全生命周期的PaaS服务。",
"VideoWorks致力于成为百度智能云上所有音视频的统一入口，目前已集成了BOS（对象存储）、CDN（内容分发）、MCT（音视频转码）、VCR（视频内容审核）产品，后续会接入VCA（视频内容分析）、智能编辑、智能去重等更多的音视频处理能力。",
"此外，VideoWorks引入了工作流（workflow）能力，用户可根据自身业务需求在console可视化灵活配置音视频的处理流程，一次任务下发即可按照既定流程处理完成，方便快捷。"
), Per.BASE_DUXIAOMEI);
Text2AudioResponse response = client.text2Audio(request);
}视频合成
视频合成功能支持讲一端视频编辑的Timeline（不同媒体分类组成的时间轴数据）编码合成输出。
使用如下代码可以发起合成。
- 接收合成请求Timeline的Json字符串，直接发起合成。
private void createVideoEdit(BvwClient client) {
String jsonString = "{" +
" \"bucket\":\"testbucket111\"," +
" \"title\":\"default\"," +
" \"cmd\":{" +
" \"timeline\":{" +
" \"video\":[" +
" {" +
" \"key\": \"name\"," +
" \"list\": [" +
" {" +
" \"type\": \"image\"," +
" \"start\": 0," +
" \"end\": 10.5," +
" \"showStart\": 0," +
" \"showEnd\": 10.5," +
" \"width\": 1," +
" \"height\": 1," +
" \"xpos\": 0," +
" \"ypos\": 0," +
" \"duration\": 10.5," +
" \"extInfo\": {" +
" \"style\": \"relief\"," +
" \"lightness\": 0," +
" \"contrast\": 0," +
" \"saturation\": 0," +
" \"hue\": 0," +
" \"speed\": 1," +
" \"transitionStart\": \"white\"," +
" \"transitionEnd\": \"black\"," +
" \"transitionDuration\": 2," +
" \"mirror\":\"hori\"," +
" \"rotate\" : 180" +
" }," +
" \"mediaInfo\": {" +
" \"key\": \"77f70ad4cf57e46af1b1249999c62918.jpeg\"," +
" \"bucket\": \"testbucket111\"," +
" \"fileType\": \"image\"" +
" }," +
" \"uid\": \"d0a7a580-fe36-4baf-b4ac-193565925b01\"" +
" }" +
" ]" +
" }" +
" ]," +
" \"audio\":[" +
" {" +
" \"key\":\"name\"," +
" \"list\":[" +
" ]" +
" }" +
" ]," +
" \"sticker\":[" +
" ]," +
" \"subtitle\" : [" +
" ]" +
" }" +
" }" +
"}";
String notification = "notificationName";
Map<String, Object> editBody = new ObjectMapper().convertValue(JsonUtils.jsonNodeOf(jsonString), Map.class);
VideoEditCreateRequest request = new VideoEditCreateRequest(editBody, RefererType.rmrb, notification);
VideoEditCreateResponse response = client.createVideoEdit(request);
}- 自己组合Timeline数据对象
自己组合Timeline对象（Map<String, Object>) ，将组合好的符合Timeline规则对象作为参数传入VideoEditCreateRequest构造函数即可
private void createVideoEdit(BvwClient client, Map<String, Object> cmd) {
Map<String, Object> editBody = new HashMap<String, Object>();
String notification = "notificationName";
editBody.put("bucket", "userBucket");
editBody.put("title", "editTitle");
editBody.put("cmd", cmd);
VideoEditCreateRequest request = new VideoEditCreateRequest(editBody, RefererType.rmrb, notification);
VideoEditCreateResponse response = client.createVideoEdit(request);
}查询视频合成结果
使用如下代码可以查询视频合成结果。
private void pollingVideoEdit(BvwClient client) {
long editId = 123;
VideoEditPollingResponse response = client.pollingVideoEdit(editId);
}
