Azure Media Services v3创建资产筛选器返回BadRequest
代码和清单都包含在下面。资产期限为00:00:26.433万
我试过调整轨道，没有轨道。已尝试调整时间参数。
-
有什么问题吗？
-
API是否有可能报告更多错误信息？
-
能否创建一个示例，展示如何使用AssetFilters.CreateOrUpdate(带和不带跟踪筛选器(？
代码

我们在资产过滤器中遇到了一个已知的错误，该错误已修复并已投入生产。看起来你可能遇到了同样的错误。该团队还在.NET SDK中修复这个问题并将其推出。
现在，您可以先删除所有在v3 API中创建的旧过滤器吗。若要解决此问题，您需要首先从此帐户中删除所有旧资产和全局筛选器。当我们从预览转移到GA时，我们在过滤器上出现了版本控制错误匹配，这导致了不匹配(因此也导致了您看到的错误消息(。如果您查看stacktrace，您应该能够获得更详细的错误消息。它通常会显示版本冲突问题。请告诉我们您在错误的详细信息中看到了什么。
Carlos，今天为你看这个。抱歉耽误了。
我使用Postman集合只是想看看.NET SDK到底发生了什么。看起来以下文件管理器工作正常。我认为您遇到的问题与创建新PresentationTimeRange的代码行有关。视频点播过滤器不需要presentationWindowDuration和liveBackoffDuration的值。它们仅用于带电过滤器。请尝试使用以下内容。
new PresentationTimeRange(scaledStartTime, scaledEndTime, null, null, (long)timeScale, null);
{
"properties": {
"presentationTimeRange": {
"startTimestamp": 0,
"endTimestamp": 264333333,
"presentationWindowDuration": null,
"liveBackoffDuration": null,
"timescale": 10000000,
"forceEndTimestamp": null
},
"tracks": [{
"trackSelections": [{
"property": "Type",
"operation": "Equal",
"value": "Video"
},
{
"property": "Type",
"operation": "Equal",
"value": "Audio"
}
]
}]
}
}当我通过.NET SDK运行它时，我会仔细检查一下这是否是一个问题。我认为我们这里的问题可能是presentationTimeRange的值在这里的当前Swagger文件中都标记为"REQUIRED"：
