kandi X-RAY | gst1-java-core Summary

gst1-java-core is a Java library typically used in Data Processing, Stream Processing applications. gst1-java-core has no bugs, it has no vulnerabilities, it has build file available, it has a Weak Copyleft License and it has low support. You can download it from GitHub, Maven.

gst1-java-core is a set of Java bindings for [GStreamer 1.x][gstreamer]. GStreamer is an open-source, pipeline-based multimedia framework written in C. It allows a programmer to create a wide variety of media-handling pipelines inside applications, from simple media playback, to encoding, live-streaming, analysis, machine learning, WebRTC and more. GStreamer is designed to be cross-platform, and binaries are provided for a range of operating systems. gst1-java-core is actively tested on Linux (x86 and Arm), Windows and macOS, but should work on any OS with Java, JNA and GStreamer support. The bindings are in use in a wide variety of commercial and open-source projects, across desktop, server and embedded.

Using Gstreamer for Android with JNA & gst1-java-core?

GStreamer recording a stream to a wav file with wrong duration

GStreamer - Cannot link Decodebin element (NOFORMAT)

QUESTION

Using Gstreamer for Android with JNA & gst1-java-core?

Asked 2021-Mar-12 at 00:33

Before we start allow me to just say that I know that it is possible to integrate Gstreamer into Android natively using C code as done in the Android Tutorials themselves.

This question is not related to simply just getting Gstreamer running on Android but rather running it on Android using the pre-existing native Java wrapper library gst1-java-core alongside JNA inside of Android Studio in a new Native project. However, if Native C code is the only way do let me know if you have tried and failed what I'm trying to do.

Lets begin.

System Information:

OS: Linux Ubuntu 18.04
Android Studio Version: 4.1.2
Java version: 8
SDK version: 30 (targetting API 21)
NDK version: 21 (also tried 23)
Testing Device: Samsung Galaxy Tab S6 Lite (even though haven't gotten there yet)

Process involved setting up a brand new project in Android Studio and choosing Native C++ as the Project Template followed by keeping everything else default including the toolchain. Once the project was built and finished it's Gradle business I did the usual git init and set it up in Git. Following that I downloaded and added the gst1-java-core-1.4.0.jar from the releases page to the "libs/" directly inside the "app/" folder.

Once I had done so I modified the build.gradle file in the app directory to match this Gradle Gist.

This was then naturally followed by a Gradle sync and when that had completed correctly I went to my MainActivity.java and added two lines of code total. First at the top:

So it was my mistake not knowing enough about Android and the sub systems to know that even though Android is primarily developed in Java it does not support running Java "natively". This means that JNI is not relevant as according to Wikipedia JNI is:

In software design, the Java Native Interface is a foreign function interface programming framework that enables Java code running in a Java virtual machine to call and be called by native applications and libraries written in other languages such as C, C++ and assembly

So in saying that - because Android does not run a JVM but rather it runs Native C on a Linux Kernel this means that trying to integrate a "java wrapper" through the JNI is not currently possible on Android.

Because of this - the common solution and following Gstreamers official tutorials appears to currently be the only way to use Gstreamer in Android.

I only have myself to blame for thinking that everyone else had just "missed" JNI and gst1-java-core and that I somehow knew better than even the Gstreamer official website itself.

I felt like answering this question though because if anyone else goes down the wrong track I can now officially suggest to following the official tutorials and create an Android App with Native support so that you can compile and integrate the C code directly from Gstreamer and then make your app work like that.

I can currently say that following the above paragraph's advice resulted in me creating a working Android application with a Gstreamer live stream currently up and running using a custom pipeline. I'm not going to say it was easy; because it isn't; especially if you are not great at C programming. But it is definitely doable and the tutorials are good.

QUESTION

GStreamer recording a stream to a wav file with wrong duration

Asked 2018-Jun-14 at 01:00

I'm recording a wav file using GStreamer receiving G711 flow through a UDP port. Any wav player can play the file, but shows a wrong duration and cannot fast forward. I believe that GStreamer writes the header at the beginning with empty data.

This pipeline can reproduce the issue:

How do you stop the pipeline? If you interrupt the pipeline with ctrl-c it may indeed be that the header finalization is skipped. Run your pipeline with the -e option so that on ctrl-c your pipeline gets stopped gracefully.

QUESTION

GStreamer - Cannot link Decodebin element (NOFORMAT)

Asked 2017-Jun-17 at 09:41

I'm using GStreamer 1.10.4 in order to perform raw video streaming playback in a Java application.

This this the command I'm using for the video playback outside my Java app: It works fine

ANSWER

Answered 2017-Jun-17 at 09:41

I've found the issue. The appsink capabilities do not match with the ones of the decodebin. I solved the issue by removing the decodebin element and replacing it by a videoconvert element instead and the video playback works.
