Record tablet's screen AND audio

Question

I\'ve been wondering, after trying this command on my Nexus 7:

adb shell screenrecord /sdcard/demo.mp4

Is there a way to record the screen

Answer 1

I could do it this way :

• connect the Android device to computer with a jack cable (headphone output to microphone input);
• record video with adb shell;
• record audio with Audacity (or anything else)
• then merge video and audio with a video editor (pitivi, openshot, avconv...)
