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.

Have you also downloaded android-support-v4.jar in the link of Nice Spinner? If not, the spinner will cause a crash. Please try it.

You have hit the point - i readed to fast and mixed something; because there exists android-support-v13.jar also. So i had to check out, that v13 does not replace v4.
My v4 was from 2013! and now i have it from 25. 11.2015.
Thanks for your work!

This is the last update that I will do for this library. Attached are new B4A library files, an updated B4A project, and the Java source code. Amend the Java code to your like should you want to add additional functionality.

This update adds the following:
1. Specifying the folder name of where you want to store the captured video (starting from the root directory of your device). See the example code. If the folder(s) that you specified does/do not exist then the library will create them.
2. Append a date/time stamp to the video name. Thus, the video name will be xxxxx_yyyyMMdd_HHmmss.MP4 (to prevent overwriting video files with the same name)
3. Customise the toast message to be displayed for the Max Duration and Max Files Size reached events - see the example code
4. Return a list of the supported video preview sizes for the selected camera of your device.

An update as advised by @Mahares :

1. Bug fix for devices that do not support FOCUS_MODE_CONTINUOUS_VIDEO
2. Bug fix for devices that do not support a Flash/Torch
3. Added an event in B4A that returns the remaining recording time relative to the preset recording time - see the attached sample B4A project for the new event added.
4. Add / don't add a timestamp to the name of the recorded video file.

Posting:
1. Updated B4A project
2. Updated B4A library files
3. Updated Java code

Brilliant!! thanks again Johan. Just one question, if one changes the video mode to 3GPP instead of MP4, wouldnt that have a smaller file size?
Will look into that...

Hi Johan.

Great Library.:)

I have a couple of issues though:

On a particular device type I am getting NullPointerException error on AVC1.setStartStopRecording however this device only has a front camera it does not have a back camera. (if I choose a camera that does not exist I get a different error and the folders are set correctly).

This process works fine on the other devices that have both cameras.

I have a maximum record time set at 60 seconds and if I allow this time to expire and end automatically the recorded video will not always play back, appears to be corrupted?
if I stop recording 1 second before the time runs out, by calling AVC1.setStartStopRecording the video always saves correctly and can be playback.

Also again with the maximum record time set, once I have called AVC1.setStartStopRecording and recording has completed and I am finished with video, a while later I still get a toast message reporting maximum file size reached?
if I turn off messages this does not appear but I still get a notification sound. if I try to record again before the notification the application errors,
if I set StopCameraOnMaxSizeDuration = False then I don't get the error.


Regards
Steve

Just to be sure, are you using the library and project in post #26 above?

Hi Johan,

Yep I am using the library files from post #26
The device is the Acer DA241HL and a slightly new model plus the Viewsonic (VSD224) but same spec both have only one camera and its on the front.
Your library works great on the other tablets I have; Hudi, Samsung T3, Kurio 10" and a rugged 7" (Chinese import)

I have worked around the issue with the record timer and max file size reached etc, just the null pointer exception.

Steve

Ok Steve - will add some debugging lines in the wrapper so that we can trap the error and fix it. Does your devices with the front camera only start the video recording at all i.e the error appears but the app runs?

Hi Johan,

The app runs OK. there is no preview of the camera output, the error only occurs when you toggle AVC1.setStartStopRecording.

On my other devices, again there's no preview. But the output of the camera displays correctly when you toggle AVC1.setStartStopRecording.

Thanks
Steve

Steve, please try the attached library files. The B4A project is unchanged as what I have posted in post #26 above. Only the library changed.

Hi Johan,

I am back in the office tomorrow (I left my Acer All In One there and forgot it) I will try it out and let you know.

Many Thanks

Here is an update based on the feedback received from Steve (@SJQ). Posting an updated B4A project and all the library files that you will require. Take note of all the files in the project's /Objects/res/bla..bla..bla folders in case you start a project from scratch. Have done the following changes:

1. It should now (hopefully) support devices with
a. front camera only
b. back camera only (I could not test this so it will be good to have some feedback on this)
c. font and back camera​
2. It will extract the supported quality parameters for each of the available camera(s) and the spinner on the right (SUPPORTED QUALITY) will be populated according to your selection of the spinner on the left (FRONT / BACK).
3. The spinner on the left (FRONT/BACK) will be populated based on the cameras that your device supports.
4. It tests for the presence of any sort of camera(s) on a device (front, back, front & back)
5. It tests for the presence of a flash

It would be great to have some feedback from you especially from those of you that might have devices with a back facing camera only (with and without a flash) and devices with a front facing camera only (with and without flash). I have tested it on 3 x devices:
1. Front and Back camera with flash at the back
2. Front and back camera with no flash
3. Front camera only with no flash

Please note:
1. it does not support the new camera API
2. There are still lots of Log messages being printed to the B4A log from the library for debugging purposes.

Hi Johan,

Well that was interesting. for some reason the camera is not there...

I have run up the Camera sample that uses the Camera Library (V2.20) and that's working ok on the same device.
Front Camera Only, No Back camera and no flash.

When I use the camera library (V2.20) and if I try to specify rear camera the screen flashes for a second, no log messages, and just returns to the front camera.

So, what could be the cause of that? Is this something to do with the new Camera API?

Regards
Steve

What version of the OS is running on your device Steve? This is mind boggling...why would it say there is no camera? I see the message in the log. It is one of the debugging messages that I have added. Runs fine on my device with a front camera only (KitKat). Very puzzling.

Hi Steve

If you can, please try with the attached library files. Have changed a call in the library from hasSystemFeature(PackageManager.FEATURE_CAMERA) to hasSystemFeature(PackageManager.FEATURE_CAMERA_ANY)

Also comment the two lines as what I have done in the following code (lines 129 and 130):

B4X:
Sub b1_Click
   
    Log("SELECTED INDEX = " & ns2.SelectedIndex)
'    Log(r3.Get(ns2.SelectedIndex))
'    Log(r4.Get(ns2.SelectedIndex))   
    avc1.setStartStopRecording
   
End Sub
