AS3-检查flv中是否有视频
[英]AS3 - check if flv has video in it
问题描述
I'm a n00b @ AS but I have managed to put together a video player using NetStream that suits my needs perfectly. 
我是n00b @ AS，但我设法使用NetStream组合了一个完全适合我需求的视频播放器。 The thing I'd like to add is that it would display a certain image if the streamed .flv clip only has audio track in it (mp3 converted flv). 我要添加的是，如果流的.flv剪辑中仅包含音频轨道（mp3转换的flv），它将显示特定的图像。
Q: is there a way to check if the .flv I'm streaming has video in it? 问：是否可以检查正在播放的.flv中是否有视频？

OK, I think I found the solution. 好的，我想找到了解决方案。 Using info from "onMetaData" I can check for video codec (videocodecid) and it seems to return "undefined", if the .flv only contains audio. 使用“ onMetaData”中的信息，我可以检查视频编解码器（videocodecid），如果.flv仅包含音频，它似乎返回“ undefined”。
