编码器3 SDK问题

问题描述

我正在创建一个测试应用程序，用于将流从网络摄像头/摄像头发布到WMS上的发布点。但是，我无法更改输出格式，如流的质量/编解码器/比特率。我想要使​​用的属性是readonly。或者我做错了什么？

例如：

outputFormat.VideoProfile.Codec = VideoCodec.VC1;

给出错误

错误1属性或索引器'Microsoft.Expression.Encoder.Profiles.VideoProfile.Codec'无法分配 - 它是只读的

但是应该启用/设置outputFormat.VideoProfile.Codec。

另外我如何使用outputFormat.VideoProfile.Bitrate来分配比特率和我可以像编码文件一样分配叠加图像吗？我也试过使用预设，但那些也给我错误，他们是只读的。为了记录，我使用WindowsMediaPublishingPointOutputFormat（）。

解决方案

Hi,

I am creating a test application to publish stream from webcam/camera to a publishingpoint on WMS. However I can't change the output format like quality/codec/bitrate of the stream.  The properties that I want to use are readonly. Or am I doing something wrong?

For example this:

outputFormat.VideoProfile.Codec = VideoCodec.VC1;

gives the error

Error 1 Property or indexer 'Microsoft.Expression.Encoder.Profiles.VideoProfile.Codec' cannot be assigned to -- it is read only

But outputFormat.VideoProfile.Codec should be get/set enabled.

Also how can I use outputFormat.VideoProfile.Bitrate to assign a bitrate and can I assign a overlay image like when encoding a file? I also tried to use Presets but those also gives me error that they are read only. For the record I am using WindowsMediaPublishingPointOutputFormat().
