Typedef Documentation

ExtPostpSet

typedef ExtAudioProcSet AVE::ExtPostpSet

ExtPrepSet

typedef ExtAudioProcSet AVE::ExtPrepSet

OnAlignedAudioAuxCallback

typedef OnAudioPcmDataCallback AVE::OnAlignedAudioAuxCallback

对齐后的混音音频数据回调

Parameters

callbackContext	上下文
channelIndex	通道号，不需要关注，混音仅对主通道生效
outFrame	对齐后的混音音频数据

Attention

请不要在当前线程做耗时操作

如果想要从此回调中获取媒体播放器的音频混音数据，需要调用 [enableAux] 或媒体播放器类型为 Aux

OnAudioPcmDataCallback

typedef void(* AVE::OnAudioPcmDataCallback) (void *callbackContext, int channelIndex, const AudioFrame &outFrame)

音频数据回调

Parameters

callbackContext	上下文
channelIndex	通道号
outFrame	音频数据

OnAudioProcCallback

typedef void(* AVE::OnAudioProcCallback)(const AudioFrame &inFrame, AudioFrame &outFrame)

音频处理回调函数定义

Parameters

inFrame	待处理音频数据
outFrame	处理后的音频数据，其中buffer 所指向的内存由 SDK 负责申请和销毁，用户处理后回写的数据的采样率不超过48K

Attention

请确保在当前线程完成，且不要做耗时操作

OnPostpCallback

typedef void(* AVE::OnPostpCallback)(const char *streamId, const AudioFrame &inFrame, AudioFrame &outFrame)

音频后处理回调函数定义

Parameters

streamId	流 ID, 当 streamId 为空串时，表明这是混音后的音频数据
inFrame	待处理音频数据
outFrame	处理后的音频数据，其中 buffer 所指向的内存由 SDK 负责申请和销毁，用户处理后回写的数据的采样率不超过48K

Attention

请确保在当前线程完成，且不要做耗时操作

OnPrepCallback

typedef OnAudioProcCallback AVE::OnPrepCallback

VideoCaptureFormat

typedef VideoDataFormat AVE::VideoCaptureFormat
