Capture Video of Android s Screen

Question

Forget screenshots  is it posible to capture a video of the running application in android  Rooted or non-rooted  I don t care  I want atleast 15fps   Update  I don t want any external hardware  The intent is to make it perfectly portable and every frame is captured within Android OS  If it crosses the boundaries of the app sdk  I m willing to go to OS level modifications but I would need a starting point

I guess screencast is no go cause of tegra 2 incompatibility  i already tried it but no whey  So i tried using Z-ScreeNRecorder from market installed it on my LG Optimus 2x  but it record s only blank screen i tried for 5min  and there i get 5min  of blank screen file of 6mb size    so there is no point trying until they release some peace of software that is compatible with tegra2 chipset

If you want to record the user navigation so you can test UI and other things  I recommend you to use TestFairy  It allows you to send the apk to some test users by email and see a video with all the sessions in the app and even the app crashes and device stats

It is possible to record screen video directly from your phone or tablet if your device is rooted  I m working on the SCR Screen Recorder app  To the best of my knowledge this is the only app supporting Tegra devices  including Nexus 7  and Android 4 2  At the moment the app records between 9-18fps depending on device but I m working to improve that  SCR Screen Recorder is still in beta testing phase so feel free to test it and give feedback

In Android Lollipop  5  a new feature has been added which allows screen capture which is explained here  Here is an example  Call startActivityForResult like this  startActivityForResult mProjectionManager getScreenCaptureIntent    PERMISSION CODE     Then capture the result   Override public void onActivityResult int requestCode  int resultCode  Intent data        if  requestCode    PERMISSION CODE            Log e TAG   Unknown request code      requestCode           return            if  resultCode    RESULT OK            Toast makeText this                   User denied screen sharing permission   Toast LENGTH SHORT  show            return            mMediaProjection   mProjectionManager getMediaProjection resultCode  data       mVirtualDisplay   createVirtualDisplay

If you are on a PC then you can run My Phone Explorer on the PC  the MyPhoneExplorer Client on the phone  set the screen capture to refresh continuously  and use Wink to capture a custom rectangular area of your screen over the My Phone Explorer window with your own capture rate  Then convert to a FLV in Wink  then convert from Flash video to MPG with WinFF

I didn t implement it but still i am giving you an idea to do this    First of all get the code to take a screenshot of Android device  And Call the same function for creating Images after an interval of times  Add then find the code to create video from frames images   Edit  see this link also and modify it according to your screen dimension  The main thing is to divide your work into several small tasks and then combine it as your need   FFMPEG is the best way to do this  but once i have tried but it is a very long procedure  First you have to download cygwin and Native C   library and lot of stuff and connect then you are able to work on FFMPEG  it is built in C

taranfx  without more info I m assuming since you are on StackOverFlow that you have the Android Developer Tools installed  If so you can run the emulator and then use one of the many desktop screen capture programs to capture your running application  Screenflow on the Mac works great for doing this  I am sure there are many good screen capture programs if you are on Windows or a Nix platform and I know there are some online services as well but I do not have any links nor have I used them  Here is a link for the reference document on setting up and running the emulator The Android SDK includes a mobile device emulator

My suggestion is also to use a screen recorder  such as SMRecorder  Instead of using the emulator  which is slow - especially for games and things you would want a video of  I recommend using a VirtualBox VM  with Android installed  You can connect the Dalvik debugger to it and debug you app there  If the debugger slows down you app too much  disconnect it to record the video  There are many links out there explaining how to set up the Android VM for debugging  I find it far better than the emulator   Now this does not take care of capturing screens directly on the device  in case you app uses the accelerometer  or the camera that are not available on the PC  For that I would use the android market app mentioned above
