视频和音频漂移
我想知道,录制的音频和视频通常与实际录制时间相差多少? (就像,也许有一帧被丢弃或其他什么)我分别记录两者(记录到无符号的8位PCM(44100 Hz)和原始图像数据文件中),我想知道我可以期望每个漂移多少。
提前致谢!
I was wondering, how much does recorded audio and video drift from their actual recording time usually? (So like, perhaps a frame is dropped or something) I'm recording both separately (into unsigned 8 bit PCM (44100 Hz) and raw image data files) and I was wondering how much I can expect each to drift.
Thanks in advance!

有了良好的硬件和软件,您就不会出现任何漂移。丢帧只是处理延迟的产物。
With good hardware and software you can expect no drift at all. Dropped frames are only an artifact of processing lags.
