In my project, I want render a virtual display use opengl and then encode to H264 stream, I change some code of VideoActivity


Instead pass surface to VideoPlay, I use it to create VirtualDisplay, then show a simple Presentation on it.


The third picture is the layout of my presentation, on top left, I have 1dp x 1dp ImageView with background color #ffff00.
the forth picture is actual render result, It seems it just render top left point of my layout, other part of my layout does't show up.
I'm new to opengl, I google this problem and found nothing.
Please help me! thanks.

Hi,

Thanks.

How would one go about doing this. I guess you'd need the gl3d drawable base class but there's not clear indication how.

my goal is to somehow create a gcode viewer somewhat like this:

Hi, I'm trying to combine CameraView and Transcoder in my app
they both working great,
but when I download the CameraView project to my app and used it as an implementation project
i got this weird bug in VideoDecoderOutput class line 60 -

.NoSuchMethodError: No virtual method getTextureId()I in class Lcom/otaliastudios/opengl/program/GlTextureProgram; or its super classes

I've noticed when i use the libraries as implementation as describe in the docs... its working fine but the
Egloo library in the gradle external libraries is version 23... can you tell me whats going on?

Hello!

I tried to add the library to the demo android project from the current repo and got an error. It also not importing into my project. Could you please help me with it?

I replaced
implementation(project(":library"))
with
implementation("com.otaliastudios.opengl:egloo-android:0.5.3")

Hey, I am trying to render to a texture using a framebuffer, but I can't seem to make it work, could you help me out here?

So I am setting up a SurfaceView and tried a simple rendering, which works just fine:

        val core = EglCore(flags = EglCore.FLAG_TRY_GLES3)
        val window = EglWindowSurface(core, surface)
        window.makeCurrent()

        val simpleProgram = GlFlatProgram()
        simpleProgram.setColor(Color.GREEN)
        val circle = GlCircle()
        circle.radius = 0.15F
        simpleProgram.draw(circle)

        // Publish
        window.swapBuffers()

But when I am trying to render to a FBO it crashes:

        val core = EglCore(flags = EglCore.FLAG_TRY_GLES3)
        val window = EglWindowSurface(core, surface)
        window.makeCurrent()

        val simpleProgram = GlFlatProgram()
        simpleProgram.setColor(Color.GREEN)
        val circle = GlCircle()
        circle.radius = 0.15F

        val fbTexture = GlTexture()
        val fbo = GlFramebuffer()
        fbo.attach(fbTexture, GLES20.GL_COLOR_ATTACHMENT0)
        fbo.bind()

        simpleProgram.draw(circle)

        // Publish
        window.swapBuffers()

java.lang.RuntimeException: Error during draw start: glError 0x502: invalid operation

Could you help me out with a working sample or a pinpoint in what's wrong? I couldn't glean much more from the docs.

We have a codebase that depends on some OpenGL ES drawing classes.

For example:

• take a filter that depends on OpenGL ES, e.g. https://github.com/pedroSG94/rtmp-rtsp-stream-client-java/blob/master/encoder/src/main/java/com/pedro/encoder/input/gl/render/filters/GreyScaleFilterRender.java
• refactor to use Egloo for drawing
• Egloo draws with OpenGL or Vulkan

Is Vulkan support planned? Or should I look for alternative solutions?

Hey, it seems that egloo has a compatibility issue with kotlin 1.4

java.lang.NoSuchMethodError: No static method get-impl([II)I in class Lkotlin/UIntArray; or its super classes (declaration of 'kotlin.UIntArray' appears in [...]

Hi! 👋

I am Mattia, the main developer and maintainer here, and I have enabled the GitHub Sponsor button on this repository which will let you support the library development by sponsoring my open source work through GitHub itself.

In the last years, I have spent countless unpaid hours on this and other projects, designing and developing tools that solve real problems, for everyone to use. I am very happy to know that companies of all sizes benefit from my work everyday.

GitHub is now offering you the opportunity to thank back with a sponsorship. For individuals, it could be a small amount. For companies that are powered by my tools, it could be a fairly small percentage of their revenue. In any case, your support will be greatly appreciated (and for bigger amounts, you get things like private support hours, or something else if you prefer).

https://github.com/sponsors/natario1

I will experiment leaving this as a pinned issue - for a while at least - since it's where people are most likely to see it. Sorry if this bothers you, and thank you all for your help.

Since jCenter is closing at May 1st (see https://jfrog.com/blog/into-the-sunset-bintray-jcenter-gocenter-and-chartcenter/), the artifacts for this project will not be downloadable. Would it be possible if you upload the artifacts to Maven Central or another repository?

Is there a Java Implementation of this code

I Am trying to learn Open GL and EGL , is there a Java implementation of this Code, I saw the Transcoder code has

api 'com.otaliastudios.opengl:egl-core:0.1.1', however the code is not available on Github., can we please get this code.

This is possibly a kind of niche request, but I am building an application that lets users write their own shaders. I am looking for a way to catch compile errors before they are eventually caught in draw (resulting in a Fatal exception). I have tried with the following, but this fails to compile:

            val dummyShader = """
                precision mediump float;
                void main() {
                    gl_FragColor = vec4(0.0, 0.0, 0.0, 0.0);
                }
            """.trimIndent()
            GlShader(GL_FRAGMENT_SHADER.toInt(), dummyShader)

I am not sure what else I need to do to get any shader to compile in this context (I am calling this outside of any Egloo class, in my own code).

i can not access the video in VideoActivity,so it is better to correct the uri http to https.

Please include sources and javadoc to the published artifact.
As of version 0.5.3 there are none
