Question

I m new to SDL. I m developing a media player using SDL, and now I met the problem that the audio callback function is sometimes not called in time, and cause the audio a little fitful.

我使用这种编号打开音响装置:

wanted_spec.xxx = xxx;
wanted_spec.callback = audio_callback;    //audio_callback is my audio callback function
SDL_OpenAudio(&wanted_spec, &spec);

我的顾问是Windows XP。

Do you know anything about that? Can someone suggest how to synchronize data feeding to callback function with 0 latency.

我的问题不是通过SDL_LoadWAV提供整个编织物,而是希望通过PCM样本(可能是1024个样本)。 (千美元) 设计就像我正在获得PCCM样本一样。

But issue is, callback function is not called in time or calling is delayed which causes the sound to be fitful. I m not able to syn passing of data to callback function.

Can you please suggest a way to synchronize passing data (Samples) to callback function or provide some application where data is passed in samples?

我们需要真正的价值观来充分回答你的问题。

What is your attempted buffer size?

人们还认识到,SDL通常不给你想要的东西,从而检查实际的缓冲规模。

我先在窗户上使用一条双双双向ming光灯,使我缓冲,不管我要求什么,都少于第二次。
