Official SCR Screen Recorder thread
Check out SCR Screen Recorder, the Android most comprehensive screencast recording app.
SCR Screen Recorder supports all Android versions since 4.0 and utilizes the best encoding method available on each platform. Since the first release in early 2013 SCR Screen Recorder is frequently updated and new features are added regularly.

Unique features:
• SYSTEM AUDIO (requires root) - On most devices you can directly record in-game audio without quality loss caused by microphone recording speakers output. The "Internal + Mic" option allows to add a microphone commentary to the system audio recording. At the moment this feature is not available on Android 4.2 but it'll be added soon.

• FACE CAM - Share your emotions by adding a front-facing camera to your video. You can move the camera overlay around so that it doesn't obstruct important controls.

• NO ADS - Unlike other "free" screen recorders SCR never display any ads. Development of all my apps is supported only by donations.

• SETTINGS - No mater if you prefer to select simple presets or manually tweak every setting we've got you covered. SCR supports many customizations and provides performance and stability stats.

• ALPHA FEATURES - Let us know what's important to you in this thread or by joining SCR Alpha Testing Google+ community at http://goo.gl/PGYZ8r

SCR Screen Recorder uses various hacks and unofficial APIs which may not work on some devices and ROMs. If you encounter any issues try experimenting with different settings. In case that doesn't help select "Send bug report" from SCR Settings menu or ask for help in this thread. Note that some devices simply don't support certain encoding options so it doesn't make sense to complain that GPU+ image transformation doesn't work if GPU transformation works fine.

Google Play ban and "Dangerous app" warning
SCR Pro got recently banned on Google Play and my developer account got terminated.
This is probably caused by the recent Google Play raid on apps switching SELinux to permissive mode. Unfortunately they haven't sent me the warning so I haven't got a chance to remove this feature. See SELinux section below for more details.

Free SCR Pro for everyone!
I don't want to charge anyone twice for the same app and no publishing method allows for migration of thousands users who already paid for the app, so I decided to release SCR Pro for free!
You can grab the APK below and enjoy all the features of the latest release of SCR Pro on Google Play. No time limits, watermarks etc. Simply full-featured best Android screen recorder for free!
Please consider donating to me, especially if you haven't purchased SCR Pro before, so that I continue development of this app.
SCR Screen Recorder Pro v1.0.5
SCR 5+ Pro v0.1.3 (no root, NO INTERNAL AUDIO, requires Lollipop)


In case you don't know how much to donate, the previous price of this app was $5 :)

SELinux details
SCR Root switches SELinux to Permissive mode when it's running and restores it to the initial value after it's turned off. On most KK+ devices some SCR features won't work without disabling SELinux. Mainly the internal audio recording. If you'd prefer to try using SCR in SELinux enforcing mode let me know (state your Android version and why you need SELinux enabled during recording) and I may make this and option in SCR Settings.

FAQ
I’m getting error message when I start recording, what should I do?
Try changing the resolution or switching between CPU/GPU image transformation mode. Some devices don’t support all settings combinations. If you can’t get any settings to work please tap “Report” button on error dialog and send a full report email including system log.

The recording works fine except the strange colours
Select “Inverted color fix” in SCR Settings.


Video contains some random colors instead of my screen
This is caused by device video encoder crash. It usually can be fixed by changing Resolution.


The video is sideways, how do I rotate it?
Just like default Android Camera app SCR checks the screen orientation when the recording is started and adds orientation metadata to the video file. Some video players (e.g. VLC) ignore orientation metadata and always display video horizontally. YouTube and default android video player can detect orientation metadata correctly and play vertical videos. If you want a video to use vertical frames instead of rotation metadata select "Show advanced" in SCR Settings menu and then select "Vertical frames". Note that hardware video encoders and video players on many devices don't support vertical frames especially on high resolutions.

My phone gets really laggy when I start recording
Phones hardware is not designed to record HD video and play 3D games at the same time so I have to push the limits. There is always going to be some slowdown. You can reduce a lag by reducing resolution and frame rate. Lower frame rate and lower resolution means that your phone needs less power for video encoding and has more spare resources to run other apps and games. If you’r running Android 4.3 try GPU+ image transformation mode which is much faster on some devices.

So what are the benefits of this over screencast?
There are quire a few benefits of SCR over Screencast:
  1. SCR supports Tegra devices
  2. it works on Jelly Bean
  3. on many devices it's much faster (e.g. on Nexus 4 you can record [email protected] with minimal CPU ussage)
  4. SCR UI uses an floating window displayed ontop other apps so that you can start recording without capturing recorder UI
  5. it's in active development i.e. I keep adding new features and fixing bugs

Hmm... I haven't seen that one before. This looks like some generic Android error message. Do you always get it or just once?
What device/Android version are you using?
Make sure your're rooted (i.e. open SuperSu or Superuser and make sure it doesn't complain).
When i click setting it always fclose dude,im rooted already

What about this? Happens all the time.
Many HTC devices are still not working corrctly. Especially on Android 4.0.x and 4.1.x. 4.2.x is a bit more stable.
I'm working on dedicated software encoding option to support problematic devices including HTX One.
This still require couple weeks of work. I'll be releasing an update with this encoder in second half of September.

Good thing you made this thread finally! I have not had any problems after some updates on my samsung galaxy tab 2 with cm 10.2 ;)
And gpu+ is faster for me that normal gpu rendering but cpu rendering is fastest, i don't know why. I don't know why other screen recorders are so slow compared to this but i am glad i found this some months ago. :good:

---------- Post added at 04:04 PM ---------- Previous post was at 03:45 PM ----------

Also there will be recording app called everplay for android but i don't know when because its gonna take some time to make it possible record without root but its for ios already. When it will be released for android i should record sound too like on ios, so you could get code from them to record sound. But even mic make my tab lag more.

Love it! Best functioning, and looking, screen recorder out there.
Still I am dieing for the audio recording feature, I know its not easy or even possible but it is the single and only feature this app is missing from perfection.:good:

If you’r running Android 4.3 try GPU+ image transformation mode which is much faster on some devices.
I'm not too familiar with the new features in Android 4.3. Why can GPU image transformation be faster with 4.3?
I looked on the official page, but i'm still not sure.

The official 4.3 news page says something like this:
Android 4.3 builds on the performance improvements already included in Jelly Bean — vsync timing, triple buffering, reduced touch latency, CPU input boost, and hardware-accelerated 2D rendering — and adds new optimizations that make Android even faster.

For a graphics performance boost, the hardware-accelerated 2D renderer now optimizes the stream of drawing commands, transforming it into a more efficient GPU format by rearranging and merging draw operations. For multithreaded processing, the renderer can also now use multithreading across multiple CPU cores to perform certain tasks.
Is the multithreaded processing the additional benefit of using GPU image transformations over using the CPU?

P.S.: btw. I like the app, keep up the good work! :)

It's not exactly about multithreading. GPU and GPU+ image transformation modes use OpenGL ES 2.0 to process the screen content (scale/rotate/change color format) in contrast to CPU mode which simply copies different color values from one memory buffer to another.

The difference between GPU and GPU+ modes is quite subtlr. GPU+ takes advantege of a new internal API introduced in Android 4.3 which allows to eliminate some inefficient OpenGL operations. This change is not advertised in release notes as it's quite a minor change in an internal API. If every such change was included in the release notes it would quickly grow to a size of a novel ;) My hunch is that this changes are being added to allow some new features of Chromecast in the future... but this is just a speculation.

my htc sensation only record in horizontal
What happens if you try recording in portrait mode?
Note that some video players ignore rotation metadata included in the video and always display it horizontally. Default Android player and YouTube can handle metadata correctly and display portrait video vertically.

I would agree with another poster, if its ever possible to just record audio output people would make you a god lol.

That and using two programs that use the mic at the same time :p. i should have known you would be on this site haha.

Also, it seems I get really inconsistent file sizes with only the frame rate setting, like one file is 12.2 mb but is 8 minutes long (vlc says 8.548 fps) and another one is over 800 mb and is 11 minutes long, but has 75 fps from what vlc says. Strange i think

This is expected behavior. File size is proportional to frame rate. At 8fps encoder needs to store 8 screenshots a second, at 75fps 75 screenshots needs to be encoded. So 10 times more screenshots requires around 10 times more storage space.
