Native audio recording #5

Open polarby opened 1 year ago

Currently there is not support to capture device audio within flutter. In order to render widgets that do not have a set audio file (eg. live streams), but rather can only be captured by recording the device audio input.

Please provide packages or approaches to target this issue.

我不是很确定可不可以实现,就是通过按帧分离音频出来,对应于当时的图片帧,然后再通过 ffmpeg命令合成还原出来; i am not sure that is right, if we can divide the audio by the time of the image frame, then we can compose it
