WMAudio Encoder DMO 滤波器剪切声音
我正在尝试使用 WMAudio Encoder DMO 过滤器来录制从麦克风捕获的声音，但它会在声音结束时缩短大约 1-2 秒的录制时间。有人遇到这个问题吗？也许 DirectShow 的 WMA 捕获有任何替代方案？
I'm trying to use WMAudio Encoder DMO filter to record captured sound from the microphone, but it cuts about 1-2 seconds of recording in the end of sound. Does anybody faced this problem? Maybe there are any alternatives for WMA capturing for DirectShow?

您不会使用
WMAudio Encoder DMO进行捕捉、录制，是吗？它只是一个编码器。您所指的症状 - 听起来好像在过滤器图中刷新数据存在问题，当您停止编码某些内容时，不会处理待处理的剩余数据，并且它不一定是WMAudio Encoder DMO。也许您可以快速将编码器更换为另一个编码器，看看您是否对这个替代选项有更多的运气，这将首先表明有故障的组件。
You don't capture, don't record with
WMAudio Encoder DMO, do you? It is an encoder only. The symptom you are referring to - it sounds like there is a problem with flushing data in your filter graph, when you stop encoding something is not processing the pending remainder of data, and it is not necessarilyWMAudio Encoder DMO.Perhaps you could quick swap the encoder with another one to see if you have more luck with this alternate option, and this would suggest the faulty component in first place.
