[Linphone-developers] Does mediastream2 support local writing

[曹贵林]

Hi buddies, 

I successfully send video and audio to remote host through mediastreamer2 framework. Now I want my application to store the video and audio data into a local file, while sending it to remote host. I go through the source code of mediastreamer2, but fail to find such a filter. 

My question is: 

Does mediastreamer2 support writing the audio/video data to a local file? Or I have to write the filter myself? 

Many thanks in advance.
