AWS Elemental Media Converter 如何使用 .Net C# 创建作业缩略图

Answer 1

此代码解决了我使用 Aws 元素媒体转换器生成缩略图的问题。 使用以下参数传递 outoup 对象：

Amazon.MediaConvert.Model.Output outputThumb = new Amazon.MediaConvert.Model.Output();
outputThumb.ContainerSettings = new Amazon.MediaConvert.Model.ContainerSettings { Container = Amazon.MediaConvert.ContainerType.RAW };
outputThumb.NameModifier = "_thumbnail";
outputThumb.Extension = "png";
outputThumb.VideoDescription = new Amazon.MediaConvert.Model.VideoDescription();
outputThumb.VideoDescription.CodecSettings = new Amazon.MediaConvert.Model.VideoCodecSettings();
outputThumb.VideoDescription.CodecSettings.Codec = "FRAME_CAPTURE";
outputThumb.VideoDescription.CodecSettings.FrameCaptureSettings = new Amazon.MediaConvert.Model.FrameCaptureSettings {
  MaxCaptures = 1,
  Quality = 100
};

ofg.Outputs.Add(outputThumb);
