Info:
New ScreenRecorder in town! This one performs perfectly on Android 4.4 KitKat. It uses the native "screenrecord" binary from 4.4 ROM which give very smooth results. (All ScreenRecords that are not using the "screenrecord" binary will not work on Android 4.4 KitKat). Ugly Icon will be replaced soon (first name was KitKat ScreenCast thats why the icon says 'KKSC', Icon and market name will be changed soon)

<-- BEFORE USING THE APP, PLEASE READ THE TEXT BELOW!!!!! -->

Note: While recording your device may become a bit laggy, Recorded video (when played on PC) is 100% smooth

Steps:
1. Fill in the path of the destination file. this may not include symlinks, a hard links to your sdcard is automatically placed in the first input field.
2. Choose a bitrate, the default given bitrate is 4000000, which is 4Mbit. Higher bitrate means better quality. I prefer 8-12Mbit.
3. Press "Start Recording" to start recording the video, the app will now minimize, when you are done with your recording press the notification that popped up. this will stop the recording.

If something doesn't work instead of rating 1 star please post it here so I can help fix it.

Sometimes you need to choose odd destinations such as /cache or /data to make it work.
for example I recorded to /data/filename.mp4 in this video:

Today I've made a set-up for a screenrecording app, it only supports android kitkat, since it uses the "recordscreen" binary.
Very early release, but works pretty neat, afaik this is the only screenrecorder atm that works on kitkat. (i have tested 3 others and they didn't work)

oh it worked for you?
for me it kept telling me some fake message about me having no root. which is obviously not the case.
screencast resulted in black videos, not more, other screenrecord apps crashed.

but i did some searching on "kitkat screenrecorder" and it seems there are already like 3/4 apps that are almost the same as mine (but were posted earlier), all screenrecorders using "recordscreen" binary work on kitkat, all others dont work guaranteed.

Curious as to how you modified the binary to allow longer recording...
Is it a case of hex editing the binary and patching out the 180s restriction (i.e. changing it to a higher value)?
I have no idea how to edit compiled binaries and would be interested in learning a few tricks!

Thanks for posting ^^. when doing it from source its really a minor change, when doing it with a hex editor it can be harder, but still very easy.
I recently hexed out a message that was spamming "mCompEngine is NULL" out of camera.msm8960.so, without any issues, just fill the actual spot with zeros and its done

Hi broodplank,

The screen recording itself works great but I'm having a couple of issues.
I backed up the current binaries and then installed the hacked binaries but I'm still unable to record for longer than 3 minutes. Also, clicking on the notification to stop the recording simply brings me back into the app. I have to actually manually click on the Stop Recording button inside the app.

I'm using the latest version (v1.5) and have a HTC One, if that makes any difference.

Great to see that sound recording will hopefully be available soon as well :)
