AWS Elemental Media Converter 如何使用 .Net C# 創建作業縮略圖

Answer 1

此代碼解決了我使用 Aws 元素媒體轉換器生成縮略圖的問題。 使用以下參數傳遞 outoup 對象：

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);
