B4A Library Vitamio 5 (Version 5.2.3)

VITAMIO 5

a B4A-wrapper of Vitamio5 (version 5.2.3 of January 7, 2018)

This is an update of Vitamio and wraps version 5.2.3 of Vitamio. The original java-sources can be downloaded here.

All donators will receive an e-mail with download instructions.

New:
-The text-relocations problem with ffmpeg has now been resolved. You can now target the most recent versions of Android with the included platforms. I tried SDK 26 and it works fine on x86 and Arm.
-Support for arm64-v8a was also added in addition to armeabi-v7a and x86.
-Fixed a bug in the original Vitamio java-sources where the MediaController would not show correctly on SDK 24.

Unfortunately, previous versions 5.0.0, 5.0.2 and the latest version (5.2.3) of Vitamio seem to have been developed and compiled by Vitamio in a very hasty way without double-checking if things are working or not. I wrote a sample app in Android Studio and encountered two problems:

1) subtitles do not seem to work.
2) if you have a stream containing multiple audio-tracks, then changing from one format/language to another (for instance from English to French), the audio will be muted after the change.

Said problems have not yet been fixed by the Vitamio team despite developers reporting said issues. I have therefore removed the related properties, events and methods from the B4A-wrapper. If they fix them in the future with a new release, I will of course add them back to the wrapper.

However, what regards subtitle-support, I implemented another solution and I have added it to the wrapper so you can show subtitles. You can also check which character encoding to apply to the subtitles. Various subtitle-formats are supported but I have only verified the srt-format. In the demo-project, I have included some sample code to show you how to use subtitles.

Apart from what mentioned above, all the rest should work just fine.

Previous new stuff:
- a new layout named "VIDEO_LAYOUT_FIT_PARENT" was added.
- a new method to set Hardware Acceleration was added.
- a new method which permits amplifying audio.
- the method for adding headers is now called SetVideoPathWithHeaders
- a new method which lets you set Audio and Video Options (SetAVOptions)
- the methods CanPause, CanSeekBackward and CanSeekForward were removed by Vitamio in this version for unknown reasons. Probably due to a previous reported bug.
- the platforms now supported are: armeabi-v7a and x86
- added my own implementation for subtitles
- added/exposed a method to take a screenshot of the video

So if you do not use audio-tracks, Vitamio5 (version 5.2.3) should be fine.

Some other notes:
- To use Vitamio5, you need to use the #AdditionalRes attribute in your project. Please see the sample project for usage (basically you replace the path I am using in my sample project with the path to your folder where you saved the supplied res-folders on your PC).
- You need at least B4A v3.20 or later to compile your app
- I am only providing a B4A-wrapper to let you use Vitamio. Check the Vitamio site for any licensing issues.

Here is a summary of events, properties and methods available in this Vitamio5 wrapper.

Final notes:
I made available some years ago the very first wrapper of Vitamio here in the forum. Later @warwound wrapped subsequent versions of Vitamio.
I am now making Vitamio5 available here in the forum but this time as Donation ware. I have spoken with @warwound and he is fine with it.

I feel that a lot of efforts have been put into wrapping and testing Vitamio5 and that a small donation, to obtain it, is justified. The price is EUR 10,00 but of course you can donate more if you wish. You can donate using PayPal by clicking on my PayPal.Me link here:

https://PayPal.Me/moster67/EUR10

or you can use the Donation link in my signature.

After donating, please send me a PM (do not post here in this thread) and let me know your e-mail address that you used when donating with PayPal, the amount donated and the purpose (for instance Vitamio5). I prefer receiving a PM with this information so I can take note of your B4A licensed username. If you send this information by e-mail, please then include your B4A licensed username. Having your licensed B4A licensed username is important/required so I know if you are a donator or not if you ask for support here in this thread. I am sorry to say that if I receive a donation for less than EUR 10,00 and the purpose was for the Vitamio5 wrapper, I will not accept the donation. This may sound pompous but this is just to assure that the minimum price requested is received.

After receiving your donation and your PM, I will send you by e-mail (to the e-mail address you sent me in PM) a link from where you can download the wrapper along with a demo-app and instructions. The e-mail will have "Vitamio5 wrapper" as subject. If you do not receive an e-mail from me within a reasonable time (20-24 hours), please first check your spam-folder in your e-mail program. If you cannot find my e-mail, please then contact me by PM.

By donating, you are also motivating me to wrap future versions of Vitamio when they are made available. If and when they are released, I will wrap them to the best of my efforts and send all donators updated versions for free.

I presume with abb you mean App Bundle?
Unfortunately, I am not able to test uploading an app using App Bundle but it seems strange there would be problems.
Make sure to use the provided ARM-library (i.e. the library without x86 binaries which are not 64bit compatible) as already mentioned in the email you received from me.

The library I'm using is new. v5.23

I tested it on sdk30 and it doesn't work. the page is closing.
converting the app to App Bundle(.aab) does not work.
It works in apk.

In the application I converted to App Bundle(.aab), videos are working in the videoview library. but videos working with vitamio library do not open.

No idea, sorry.
I have never used App Bundle. When I find some time, I will have a look.

It works for me.
This was my test procedure:
1) Changed the included demo app to use SDK 30 as target version
2) set the library to be used: Vitamio5_23OnlyArm and cleaned the project
3) Built the project using "Build App Bundle under Project Menu in B4A IDE. Here is the output:

Output file: C:\test1\Vitamio5_23_b4a_latest\Demo\Vitamio5_Sample\testvitamio5\Objects\testvitamio5.aab
Completed successfully.

To test the app on the phone (in my case Samsung Note 9 running Android 10):
1) I currently don't have any app on Google Play Store which I can update so I copied the "testvitamio5.aab" directly to my phone. Here is a useful link for testing abb-files by sideloading: https://beebom.com/how-install-android-app-bundles/
2) I used/installed a free app from the PlayStore called "App Bundle Installer" which is useful for testing.
3) Used above mentioned "App Bundle Installer" app and installed the Vitamio demo app on my phone and it worked just fine.

I made sure to use the latest B4A version (11.0 at the time of writing this post)
I installed the SDK and the tools as suggested from the download page of B4A.
I am using OpenJDK 11. Not tested with Oracle Java 8.

Maybe you need to use OpenJDK 11?

If you still have errors, then I have probably not understood your procedure/steps of getting the error. If so, please explain step by step your procedure.

yes it works that way. I used the application at the link below to find out the cause of the problem. a conversion is being made and is working here. but it does not work when you install the application on google play and then download it from google play and install the application.

I couldn't test yet to upload in playstore at new version at the moment. but you can send your playstore apk so it can help to debug the issue

I had a better look. While the procedure I showed works, and which @Almora also confirmed to work, it does not work and will make the app crash when the app is downloaded from the Play Store.

I can confirm this since I made a demo app and uploaded it for internal testing using the Play Console and the app downloaded from the testing account did indeed crash on the phone. Just to be 100% sure, and exclude any problems with B4A and the wrapper, I also compiled the original demo project, written in Java, with Android Studio, uploaded the abb-file using the Play Console, and then tested it on my phone and also in this case, the same crash happens. I also tried setting "enableSplit = false" for "abi", which can be done in the app build.gradle file, in Android Studio and tested the generated App Bundle file but it crashed too.
So it is not related to B4A and my wrapper.

Since the APK-file works fine but the App Bundle does not, it means that the Abb Bundle, which is a publishing format, does some changes. This probably happens in the file structure since the error indicates that the library cannot be found.

I don't recall if the code for opening the library is available in the sources or not but if it is, maybe I can adapt it so the native libraries can be loaded. I have also made a post on SO to see if anyone can help and if there is a quick fix.

I will let you know later if this can be resolved or not.

OK, after further looking into this problem, the "problem" is that the APKs generated from the App Bundle leave native libraries uncompressed in the APK so they're not extracted at installation on the device, thus saving space on the device. Apparently, Vitamio is not using the Android standard way of loading native libraries, or else this exception probably would not happen. I had a look into the original Vitamio jars and I am unsure if I can change the behavior of loading the native libraries.

However, there is one easy fix, at least when using Android Studio. If I add the following line in the gradle.property file in Android Studio:
android.bundle.enableUncompressedNativeLibs = false
and then generate the App Bundle with AS, then the demo app I wrote when downloaded from the PlayStore will install and work properly on the device. This is of course defeating the purpose of Android Bundles, which is to save space, but since Vitamio is probably loading the native libraries not in a standard way, it is the only way to get it working.

As far as I am aware, B4A (and its IDE) is not using Gradle so that is a bummer (but also a lifesafer). I think B4A is using the BundleTool when generating App Bundles. It seems it should be possible to use the same option with BundleTool by setting the ApkOptimizations to use "setUncompressNativeLibraries(false). I found this snippet:
ApkOptimizations.builder()
.setSplitDimensions(ImmutableSet.of(ABI, SCREEN_DENSITY, LANGUAGE))
.setUncompressNativeLibraries(true) //should probably be "false"
.build());
The problem is that I don't know how to generate an App Bundle using the BundleTool and which parameters are needed.

There are MANY users of Vitamio and it still works very well and has some options required by users, such as rich codec support, RTMP, which are not found in other video libraries such as VideoView, ExoPlayer. It would be a pity if the life cycle of Vitamio came to an end.

I don't know if @Erel can help us?
