I am trying to record a screencast on Galaxy S5 using adb on a mac. 

cd /android-sdk-macosx/platform-tools
./adb devices
./adb shell screenrecord --verbose ./sdcard/screencast-recording.mp4

After the last line I keep getting some configuration error

Main display is 1080x1920 @44.70fps (orientation=0)
Configuring recorder for 1080x1920 video at 4.00Mbps
ERROR: unable to configure codec (err=-2147483648)
WARNING: failed at 1080x1920, retrying at 720x1280
Configuring recorder for 720x1280 video at 4.00Mbps

Any ideas how to get this to work?

  • Did you look to see if you got the video at the lower resolution? AFAIK, that message is just part of the standard "downgrade the resolution" process. – CommonsWare Apr 07 '15 at 21:53
  • So you mean I need to change the resolution? Let me check. – Katedral Pillon Apr 07 '15 at 21:55
  • How do I change the resolution of the phone? I looked in setting and haven't found much yet. – Katedral Pillon Apr 07 '15 at 21:56
  • "So you mean I need to change the resolution?" -- no, I mean you need to look in `./sdcard/screencast-recording.mp4` and see if your MP4 file is there. Though that path looks odd -- use `/sdcard/screencast-recording.mp4`. – CommonsWare Apr 07 '15 at 22:03
  • just tried the same on my s5 (vz developer edition on 4.4.2), `Main display is 1080x1920 @60.00fps (orientation=0)` `Configuring recorder for 1080x1920 video at 4.00Mbps` `Content area is 1080x1920 at offset x=0 y=0` no downsampling occurred – petey Apr 07 '15 at 22:05
  • when I had `./sdcard/screencast-recording.mp4` there was a file but it had 0 bytes. Now that I have `/sdcard/screencast-recording.mp4` (no .), there is no file at all. – Katedral Pillon Apr 07 '15 at 22:22
  • Actually I see the file now; it took a while to show. But it still says 0 bytes. – Katedral Pillon Apr 07 '15 at 22:23
