无法使用屏幕录像或电视电影在Android Nexus 4上录制屏幕

Question

On Nexus 4, with Android 5.1.1 I have the following problem that drives me mad:

When trying to record the screen (on Kubuntu 15.04) with:

adb shell screenrecord --verbose /sdcard/Download/intro9.mp4

just few seconds (1-4) are recorded and then recording stops by itself.

In the logcat there is relevant output:

The console outpus is:

Main display is 768x1280 @60.00fps (orientation=0)
Configuring recorder for 768x1280 video/avc at 4.00Mbps
Content area is 768x1280 at offset x=0 y=0

I've tried different solutions like lowering the bitrate, restarting the phone, using telecine, using different PC, turning off MTP but with no luck. In the past when faced the same problem even downgraded the Android to 4.4 but again no luck.

Did someone had this problem and how did you solved it?

PS The weird thing is that everything was working as expected initially: I was able to record about 2 minutes of screen recording with Telecine (few times). And then for no apparent reason it started to behave like this...

Answer 1

It turns out the reason is pretty simple: when Android Studio or Eclipse is running it obviously sends some adb messages periodically that interrupt the recording. The solution is stop the AS or eclipse and then to record.
