问题 I have a directshow filter that reads M2TS stream and demux it. I can render video and audio in GraphStudio and see it. My question is how can I use this filter as a live source for Expression Encoder job? I saw some recommendations saying to use subgraphs, but I am not so familiar with DirectShow to understand what it is. Thank you in advance for any help. 回答1: Expression Encoder would look for DirectShow video source devices, which are typically cameras. You might want to implement your won

问题 It seems very weird and I can't understand it, Why xesc, the output of Expression Encoder 4 Screen Capture, can't be play on Silverlight?? Why ScreenCaptureVideoProfile codec is always unknown? doesn't the left hand know what the right hand is doing?? 回答1: Answer from Microsoft Expression Encoder team Being optimized for screen capture, the XESC codec has dependencies that are platform dependant and thus doesn't really fit in the Silverlight model. http://social.expression.microsoft.com

问题 I have an year or so old application which uses Expression Encoder 3 to generate thumbnails. Few of the users are complaining that they are receiving the following exception: Could not load file or assembly 'Microsoft.Expression.Encoder.Utilities.dll' or one of its dependencies. This application has failed to start because the application configuration is incorrect. The application contains in itself the required EE3 assemblies in the setup, so as such installation of Expression Encoder is

问题 I`m new to media foundation and C++. But I want to create a virtual video capture device which can be used by Microsoft Expression Encoder. Can you tell me in which direction to look? I think it should be something working asynchronously and a source will be byte stream from mobile device. Thanks in advance. 回答1: I don't think you want to look into Media Foundation for this. Expression Encoder uses a richer API to capture video with, DirectShow . You want a virtual DirectShow camera, which

问题 I am trying to upload video created using MS Expression Encoder 4 to YouTube, but after processing any video is played in 3 seconds. Any ideas? Is it problem of encoder configuration or YouTube? Thank you. 回答1: I was running into the same issue when I encoded a video using the Expression Encoder SDK and uploading the videos to YouTube. I didn't experience the issue when I used the BaselineH264VideoProfile video profile. I also think the one that outputs WMV didn't experience the issue as well

问题 I am using VSTS 2008 + .Net 3.5 + C# + Microsoft Expression 3 SDK. I want to capture screen and output a wmv file. I tried hard but can not found C# samples from Google. Any reference samples? 回答1: Wrong kind of tool, Expression Encoder is a transcoder. It requires a video format as input and encodes it to a different output format. You'll need to create a video of the screen first. Capturing a screen shot is easy enough, Graphics.CopyFromScreen() can do that. Generating a video would require

问题 I have Expression Encoder 4 which supports two sort of source types: Live Source and File Source Now, I want to achieve my byte stream to be set as live source in Expression Encoder for live broadcasting. I have read about directshow filters but I do not know how to use it. Please let me know if you get something on it. 回答1: A typical solution is to implement a virtual camera and stream data off it. Encoder will see it as a video capture device and you will be able to select it as a video
