源视频文件使用阿里云普通的上传接口即可，上传之后，阿里云会自动转成mp4的格式，然后我们需要调用iAcsClient.getAcsResponse(request)查转码后的文件。

    1. for (ResourceTranscodeDTO resourceTranscodeDTO : data) {
    2.     QueryMediaListByURLRequest request = new QueryMediaListByURLRequest();
    3.     request.setFileURLs(httpDomain + FileConstants.getInput(resourceTranscodeDTO.getFileId()));
    4.     request.setIncludeMediaInfo(true);
    5.     QueryMediaListByURLResponse response = iAcsClient.getAcsResponse(request);
    6.     if (Objects.isNull(response) || CollectionUtils.isEmpty(response.getMediaList())){
    7.         tracer.trace("当前无对应转码或者还在转码中，自动重试尝试，fileId:" + resourceTranscodeDTO.getFileId());
    8.         ResourceTranscodeDTO transcodeDTO = new ResourceTranscodeDTO();
    9.         transcodeDTO.setFileId(resourceTranscodeDTO.getFileId());
    10.         transcodeDTO.setRetries(resourceTranscodeDTO.getRetries() - 1);
    11.         if (transcodeDTO.getRetries() == 0){
    12.             transcodeDTO.setTranscodeStatus(FAIL);
    13.         }
    14.         resourceTranscodeService.update(transcodeDTO);
    15.         continue;
    16.     }
    17.     QueryMediaListByURLResponse.Media media = response.getMediaList().get(0);
    18.     String runId = media.getRunIdList().get(0);
    20.     ResourceTranscodeDTO transcodeDTO = new ResourceTranscodeDTO();
    21.     transcodeDTO.setFileId(resourceTranscodeDTO.getFileId());
    22.     transcodeDTO.setTranscodeStatus(SUCCESS);
    23.     transcodeDTO.setRunId(runId);
    24.     resourceTranscodeService.update(transcodeDTO);
    25.     tracer.trace("该视频转码成功, fileId:" + resourceTranscodeDTO.getFileId());
