QTKit 音频静音和流缓冲状态消息

发布于 2024-10-12 09:52:35 字数 401 浏览 4 评论 0原文

我在 QTkit 中将音量静音，如下所示：

if
            ([muteButton state] == NSOnState){


    [mMovieVolumeSlider setFloatValue:0.1];
    [testMovie setVolume:0.1];

问题是音量衰减突然且突然。如何实现音量衰减的淡入淡出效果？

另外 - 我的应用程序运行 .pls 音频流文件。我将 .pls 文件嵌入到捆绑包中。在应用程序中选择流时，在流开始播放之前通常会出现短暂的延迟。我想在连接之前的短暂延迟期间显示某种状态消息（“正在缓冲”或“正在连接”）。当流开始时，状态消息将结束。有关于如何解决此问题的想法吗？

感谢您的帮助。

I'm muting volume in QTkit like this:

if
            ([muteButton state] == NSOnState){


    [mMovieVolumeSlider setFloatValue:0.1];
    [testMovie setVolume:0.1];

The problem is the volume attenuation is sudden and abrupt. How can I implement a fade effect to the volume attenuation?

Also - my app runs .pls audio stream files. I have the .pls files embedded in the bundle. When selecting a stream within the app, a short delay is common before the stream begins to play. I want to display some sort of status message ("Buffering" or Connecting") during this short delay prior to connecting. When the stream begins the status message would end. Any idea's on how to approach this?

thanks for the help.
