使用章节或时间轴标记在Azure Media Services中编码视频

Question

Is it possible to encode video in Azure Media Services with chapter or timeline markers, and if so, how?

I understand that custom encoding presets are supported. Outside of Azure Media Services, I was able to do what I am speaking of using the Microsoft Expression Encoder SDK, but I have yet to find this capability in Azure's offerings.

Answer 1

What do you intend to do with the chapter/timeline markers? If you intend to generate a progressive download MP4 (or WMV) file, then the above response holds. You can modify any of the published presets ( http://msdn.microsoft.com/en-us/library/dn619392.aspx ) for Azure Media Encoder with the Markers element:

<MediaFile ...>
<Markers
  MergeCollection="False">
  <Marker
    Time="00:00:00"
    Value="ABC"
    GenerateKeyFrame="True"
    GenerateThumbnail="True" />
  <Marker
    Time="00:00:03.0000000"
    Value="DEF"
    GenerateKeyFrame="True"
    GenerateThumbnail="True" />
</Markers>
<OutputFormat>

...

You would have to ensure that the Marker entries were within the timeline of the input video, of course.
