iPhone：视频API：实时视频流修改
[英]IPhone: Video API: Live video streaming modify
问题描述
I have a question about video stream processing. 
我有一个关于视频流处理的问题。 Is it possible to get access and modify real time video stream during recording (fe I want to add some text to video)? 是否可以在录制期间访问和修改实时视频流（我想在视频中添加一些文字）？ I can do this as a preview by getting separate frames, but I'm looking for tool which will allow me to store video with my text in video frames. 我可以通过获取单独的帧来进行预览，但我正在寻找能够在视频帧中存储带有文本视频的工具。
Probably there is already some libraries/tools available (but I haven't found any yet). 可能已经有一些库/工具可用（但我还没有找到）。
