问题 I have an application running on Android to connect and view the IP Camera. Now I'm trying to add PTZ support to application.

问题 I'm working with IP camera, and I have got Jpeg frames and audio data (PCM) from camera. Now, I want to create video file (both audio and video) under .avi or .mp4 format from above data. I searched and I knew that ffmpeg library can do it. But I don't know how to using ffmpeg to do this.
