问题 Currently I am working on an idea for a "Skype" like application. E.g people video call other people. Now I thought of running this on Microsoft Azure Media Services. However I'm not quite sure if this is possible. I found this video explaining how to make a simple stream from your computers webcam. What they do there is create a Channel (manually in the Azure environment) and stream to the ingest url . And the result can be seen in the publish url . So far so good. I understand this. But

问题 I have a media services account and want to stream AES protected Dash content. I want to use the token given by AAD for this purpose. In the key/License authorizarion policy in the Azure portal, I am supplying the following values: Token issuer: The values of the issuer is different in the token ("iss" claim: https://sts.windows.net/TenantID/) and in the discovery endpoint (https://login.microsoftonline.com/TenantID/v2.0). I have tried both of them separately. Token scope: Herein, I am

问题 I want to use Azure Media Services to provide the licenses for content protection. I created the ContentKey using the PHP SDK, and got the license URL for Widevine. I'm using packager in my side to encrypt the video. My problem is (mostly because of ignorance) that I don't know where to find the value for the parameters "--signer", "--aes_signing_key" and "--aes_signing_iv". I read in some tutorials that these values are provided by Widevine, but in my case I assumed that were provided by

问题 We are using Azure Media Services (MES processor) to transcode video files of various input formats into mp4 output format. In case we have a mxf input file we receive the following exception when trying to transcode video (with option to copyAudio ) Azure Media ReEncode error message: An error has occurred. Stage: ApplyEncodeCommand. Code: 0x00000001. This exception message is fairly generic and doesn't give much insights about reasons for it. Any idea how to keep original audio, while only

问题 I am trying to use azure media services, using c# code, for the most part using the examples I can upload an asset, publish it and then get a locator to pull it back down. I am a bit confused how I can generate a new locator e.g. if the old one expires? For example If I create a locator now at the time of uploading and encoding, I can get a url by defining this against the CloudMediaContext object. _context.Locators.Create( LocatorType.OnDemandOrigin, asset, AccessPermissions.Read, TimeSpan

问题 I am using the java SDK and followed the example on: https://docs.microsoft.com/en-us/azure/media-services/media-services-java-how-to-use However, using this example, for files larget than ~65MB I got the following error: RequestBodyTooLarge The request body is too large and exceeds the maximum permissible limit. Any idea? Thanks, 回答1: The current version of the Media Services Java SDK has a limitation on the size of the file to upload when using the provided createBlockBlob method. To

问题 I asked this question on the MSDN forums, but as always - there's no point in waiting on a reply from there. What I am trying to do for now is to enable users to trim the start and end of their videos using the Media Encoder Standard encoder and a custom preset. However because it is not documented anywhere (despite being the "recommended" encoder), I can't get it to work. Here is what I add to the standard encoding preset JSON object: customPreset.Sources = [ { 'Clips': [ { 'StartTime': '00

问题 I have my Asset and MediaProcessor ready. Now I am trying to encode my asset. When I send the request specified in the tutorial (http://msdn.microsoft.com/en-us/library/jj129574.aspx): { "Name":"CurlTestJob", "InputMediaAssets":[ { "__metadata":{ "uri":"https://wamsbluclus001rest-hs.cloudapp.net/api/Assets('nb%3Acid%3AUUID%3A429967f5-4709-4377-bab2-4680ae2a0dd87')" } } ], "Tasks":[ { "Configuration":"H.264 HD 720p VBR", "MediaProcessorId":"nb%3Ampid%3AUUID%3A2e7aa8f3-4961-4e0c-b4db

问题 I'm using the Windows Azure Media Services .NET SDK 3 to make use of the streaming services. I want to retrieve the duration of the video. How can I retrieve the duration of a video using the Windows Azure Media Services .NET SDK 3? 回答1: Azure creates some metadata files (xml) which could be queried for the duration. These files be accessed using the media-service extension https://github.com/Azure/azure-sdk-for-media-services-extensions Under Get Assets Meta Data: // The asset encoded with
