B4A Library AndroidVideoCapture - video recorder that is 100% embedded in B4A (6 Jan - new Lib Files in post 48)

The attached project is based on this project (click here). I was asked by @Mashiane to wrap it so that it can be used as a 100% standalone video recorder in B4A. It uses a custom view as the video view. The following applies to the project as it stands at present:

(Read the following and take note of especially point #2 about the folder that you need to create else the app will crash)

1. It can only be used in landscape mode
2. It stores the video files in folder /sdcard/Videos/*.mp4 - there is by default no such directory in the root folder so either create it manually or else add code in the B4A project to check if it exists and if not then create it via B4A code (sure it can be found somewhere on the forum)
3. The Zoom In and Zoom out functions can probably be controlled via a slider...but for this exercise I have added two buttons (Zoom In and Zoom Out)
4. There are a vast number of options as far as specifying video quality is concerned. I have not tested them all - as a matter of fact, I have only tested 2! So, try them and see if there is a difference.
5. The flash light can be switched in two ways (and they also work in conjunction with one another):
a. touch the view while the video recording is active
b. use the "Toggle Flash" button​
6. You will need to add some code to the B4A project to refresh the media files on you device else you will not see the recorded video in the /Videos folder - unless you disconnect your device and reconnect it again (in which case it will then show). Search the forum for how to do the refresh.
7. Take note of the permissions added to the B4A manifest files (some are not required)
I will play around with the code and post updates if and when I have figured out any other useful attributes to add.

Posting the following:
1. B4A project demonstrating the use of the video recorder
2. B4A library files - copy them to your additional library folder.

Hi @DonManfred

Running this on my Samsung S4 mini with Android 4.4.2 and working 100%. Are you using a later Android version and might it perhaps have something to do with that?

i´m using andoid.jar from v23
My device is android 5.1.1

I get shown a TOAST saying something like "failed prepare mediarecorder"
mmmm.....on my tablet with Android 4.0.4 I'm getting the same thing. Will see if I can get it sorted out. Something in the original code...

Just a simple question - have you created the /Videos folder on your device as what I have said you should do in post #1? I completely forgot about it and therefore had the same error on my tablet. When I manually created the folder the problem was solved. So, make sure you have created the /Videos folder!

Is it possible if one can perhaps specify the complete video path to save to in case I might want to save the video under File.DirInternal/<mypath> for example?

Its the original code, line 61 is avc1.setStartStopRecording; the device is an sony tablet z2 with android 5.1.1. The build in camera is working without problems in video mode.

Edit: It is / was a problem with videoQuality. Its now working with quality_low; i will try out which mode is working..

Posting new B4A library files (on request):

1. It will raise an event in the B4A project when the maximum specified file size was reached
2. It will raise an event in the B4A project when the recording duration specified was reached.

The first event encountered of the above two events will take preference and stop the recording - thus the second event will not occur.

Have also added:

1. specifying if a toast message should be displayed for the above mentioned events should one of them occur (different toast message for each of them)
2. specifying if the video recorder preview should be stopped when one of the above mentioned events occur.

This update adds the ability to select either the front or the back camera (for those that want to make selfies ;)). It also adds a method ZoomWithSlider that will allow a smooth zoom in / zoom out.

The attached example also use the libraries from the following two posts:
1. StartPointSeekBar - it adds the slider at the bottom of the video view. Use it for smooth zoom in / zoom out. Click on the blue link to get the library
2. Nice Spinner - a nice spinner to select the front / back camera from. Click on the blue link to get the library

PLEASE TAKE NOTE OF THE LINK TO android-support-v4.jar IN POST #1 OF NICE SPINNER. IF YOU DONT HAVE THIS VERSION OR AND EARLIER VERSION THAT SUPORTS SOME OF THE METHODS THEN THE SPINNER WILL CAUSE THIS B4A PROJECT TO CRASH!


EDIT: I HAVE ZIPPED ALL THE REQUIRED LIBRARY FILES TOGETHER IN THE POSTING EXCEPT FOR android-support-v4.jar. DOWNLOAD ALL THE LIBRARY FILES AS WELL AS andoid-support-v4.jar FROM THE LINK IN THE BLUE TEXT BELOW AND COPY ALL THE LIBRARY JAR AND XML FILES TO YOUR ADDITIONAL LIBRARY FOLDER.

HERE IS THE LINK AGAIN TO android-support-v4.jar - CLICK ON THIS WRITING


Note the files added (and properties set to read only) in the Object/res/... folder. They are only required for Nice Spinner and StartPointSeekBar. I have combined the attrs.xml files of these two libs Nice Spinner and StartPointSeekBar) into a single attrs.xml files - see the Objects/res/values folder of the attached B4A project for attrs.xml file.

If there is no front camera it should "default" to the default camera. Handle the visibility of the spinner in your code so that the user can't switch from front to back or vice versa while one of the cameras are active.

Posting the following:
1. B4A project demonstrating the Front/Back camera and the ZoomWithSlider additions
2. New B4A library files.

Please start reading at Post #1 of this thread if this is your first download else your project will not work!

Sorry for this problem;
I had your older versions already installed and it worked, with the version from today i get in line 39, which is loading the layout file:
B4X:
** Service (starter) Create **
** Service (starter) Start **
** Activity (main) Create, isFirst = true **
Error occurred on line: 37 (Main)
java.lang.RuntimeException: java.lang.reflect.InvocationTargetException

Did you only downloaded the Libraries and not the B4A project in post #17? See what I have said about the files in the /Objects/res/..... folders that are in the B4A project in post #17.

I loaded both, i renamed the old folder and tried it an second time. My objects/res folder contains 17 files in 11 folders, they are already write protected, i didnt change anything. My version numbers in Libraries Manager are all 1.00, except Core: 4.92
I have spsb1_value_changed as last sub, so it is the todays version. The doclet version in the xml file is 1.04.
I tried it on two devices, both worked yesterday.
