gstreamer video to opengl texture

 

 

 

 

Video decoding will be done using gstreamer-vaapi 0.10 and rendered to OpenGL texture. The QML plugin will have standard play/stop/pause/seturi commands and will draw the texture. When a scene is rendered in OpenGL textured objects are drawn at varying distances from the viewpoint, some close and some distant.Specifies the residence priority of the texture, use to prevent OpenGL from swapping textures out of video memory. Im currently combining opengl and gstreamer within my application. Right now, the gst-originated video buffers are pushed out of the pipeline with a handoff signal, and then uploaded to an opengl texture for further gpu-accelerated processing and final display on the application window. import processing.opengl. import codeanticode.glgraphics. import codeanticode.gsvideo.Use texture tex as the destination for the pipeline pixels. tex new GLTexture(this) pipeline.setPixelDest(tex) pipeline.play() Last time we talked about texturing, lighting and geometry in regards to porting fixed function OpenGL to Modern OpenGL and while it covered the basicRender to back buffer, copy the pixels to the texture image via glTexCopy2D. This is better since it keeps the pixel data on the video card, but it is In my first test program I just wanted to feed the webcam video to a texture on a rectangle that fits the entire screen.import cv from OpenGL.GL import from OpenGL.GLU import from OpenGL.GLUT import import numpy as np import sys . Video will be displayed on openGL texture provided by my program.A) HD video.

- Using gstreamer-vaapi plugin and modifying vaapisink element to use our texture for displaying (not to create texture and window). This time i made an application that reads in a movie file and renders it to an OpenGL texture. The texture is then used and rotated in a carrousel like fashion. The movie has a video stream and an audio stream, both streams are handled Im trying to render AV frames grabbed and converted from a MPEG4 video using Gstreamer to an Android (2.2)-opengl texture. Ive pretty much exhausted google and not found an answer.

I want OpenGL texture to display video using gstreamer.My requirement is to have a plateform independent video playback solution and I think gstreamer and OpenGL can be used together as a solution.

Freelancer is the largest marketplace for jobs in the world. I want OpenGL texture to display video using gstreamer.

My requirement is to have a plateform independent video playback solution and I think gstreamer and OpenGL can be used together as a solution. So, How do I save a .mp4 video out of the OpenGL textures that are displayed on a QML item?You will have you explicitly use one of the many available MM libraries out there - vlc, ffmpeg, gstreamer, libav to name a few. I want OpenGL texture to display video using gstreamer.My requirement is to have a plateform independent video playback solution and I think gstreamer and OpenGL can be used together as a solution. Free beginner-friendly OpenGL / GLUT tutorial for C, including both video and text versions. The OpenGL extension, ARBtexturecompression, used in conjunction with the EXT texturecompressions3tc extension offers a tremendous boostMost important, the individual textures within texture memory are smaller, allowing more textures to be resident in video memory. Since the video will end up on one rectangular plane, the vertex shader only needs to transform 4 vertices (or 5 with GLTRIANGLESTRIP) and map the texture to it.I also want to thank ystreet00 for helping me to get into the world of the GStreamer OpenGL plugins. To run the test yourself, check Opengl video texture. Im developing an opengl application in C on Windows using Visual Studio 10.Im trying to render AV frames grabbed and converted from a MPEG4 video using Gstreamer to an Android (2.2)-opengl texture. Rendering to a texture is a very useful technique for OpenGL programming. By binding to a Frame Buffer Object the output of a GLSL fragment shader is drawn onto a8) Bind Texture B (which will be our input texture) to the active texture GLTEXTURE0 and pass it in as a uniform to the shader. This texture, still in video luma/chroma color space is then converted into linear RGB, where simple graphics are then rendered. 2 GStreamer live mixing. The benchmark tool provided some good insights into what is possible using modern OpenGL for video processing. Fri, Nov 28th 2008. Multithread texture loading using OpenGL and WGL. By veelck.advertisement advices android C Dream Theater funny guitar humour images libraries memory management MSc multithreading music OpenGL picking programming record software solutions speed textures video. GStreamer OpenGL Plugins 0.10 Plugins Reference Manual.gloverlay. Overlay GL video texture with a PNG image. gltestsrc. Creates a test video stream. Im trying to render AV frames grabbed and converted from a MPEG4 video using Gstreamer to an Android (2.2)-opengl texture. Ive pretty much exhausted google and not found an answer. Another feature in OpenGL is Texture Mapping feature where you can apply the textures to your geometry. Once a texture is uploaded to the video memory it can be used throughout the program. There are certain steps to be followed before a texture is readily available to the program. Even if all this is asynchronous on the CPU side it still requires an extra effort from the GPU and is an extra load on the bus. Am I mistaken in my assumptions? If not, is this still the best way to stream video to an opengl texture? Rendering video textures with openGL ES.Hey all, when i switch from using vdpau in mplayer to any other video output in any other video player (xine, gstreamer, vlc, etc), i get corrupted video playback. it becomes choppy and my CPU gets eaten up. Im trying to render AV frames grabbed and converted from a MPEG4 video using Gstreamer to an Android (2.2)-opengl texture. Ive pretty much exhausted google and not found an answer. OpenGL (and hence OGRE) can support a number of different pixel formats for textures, and some GStreamer video sources can generate (and convert between) several different formats. I want OpenGL texture to display video using gstreamer.My requirement is to have a plateform independent video playback solution and I think gstreamer and OpenGL can be used together as a solution. I success in sharing OpenGL context but when I fill a texture in one thread, the draw does nothing n the other (but if I readGstreamer Pipeline : gst-launch-1.0 v4l2src normPAL ! glfilterapp ! video/x-raw,formatUYVY ! tee namet ! queue ! glimagesink t. ! queue ! videoconvert ! video/x-raw,format Thirty5Tech NYC Computer Repair Videos presents GStreamer OpenGL Plugins working with clutter-gst a video uploaded by Lubosz Sarnecki for the community to watch . The program renders an OpenGL textured quad which shows a live video stream.The OpenGL texture is continuously created in the OnIdle callback function. The next available frame in the video stream is captured first Use CoreVideo to convert AVFoundation video to OpenGL textures. This is where it gets tricky the code that follows is correct but Apple breaks some of OpenGLs core concepts, and refuses to document how or why they did it. So, How do I save a .mp4 video out of the OpenGL textures that are displayed on a QML item?You will have you explicitly use one of the many available MM libraries out there - vlc, ffmpeg, gstreamer, libav to name a few. You could also look at the code in the GSVideo library for Processing which uses GStreamer-Java and ships with the precompiled native libs for Windows and Mac, and also has some code somewhere to directly update an OpenGL texture from the video stream. Opengl video texture. Im developing an opengl application in C on Windows using Visual Studio 10.Do you know which library I can use to open and decrypt video ? Have a look at ffmpeg/libavformat/libavcodec or gstreamer. The GStreamer OpenGL Plug-ins module contains integration libraries and plug-ins for using OpenGL within GStreamer pipelines.[all] error out instead of doing nothing if an OpenGL feature is not present . [gloverlay] add support to manage texture ratio and can load jpeg files . They did not allow rendering of a video into a custom texture that is then composited inside the application into an OpenGL scene. And then there was gst-plugins-gl, which allowed more flexible handling of OpenGL inside GStreamer pipelines Ive built a small video player that grabs frames (as a string/byte array) from a movie by using GStreamer and then renders each frame to an OpenGL texture. def textureSetup(self): Setup texture in OpenGL to render video to glEnable(GLTEXTURE2D) glMatrixMode Hi all, Im trying to play a video using CodeBlocks/GStreamer/OpenGL. The video is playing, however, it is not showing on screen.glEnableClientState( GLTEXTURECOORDARRAY ) glTexCoordPointer(2, GLFLOAT, 0, texcoords ) Gstreamer now has a set of plugins for OpenGL, allowing Gstreamer to handle uploading frames at the correct time. This should make video playback smooth, while freeing Kivys main thread to do more useful things.A new OpenGL texture is created for each frame. Im trying to render AV frames grabbed and converted from a MPEG4 video using Gstreamer to an Android (2.2)-opengl texture. Ive pretty much exhausted google and not found an answer. Because it was a pain to find out exactly how to use the QT video decoder to get the texture of an video and use it in openGL, i will show it here. gstreamer opengl video sink. This topic has been deleted.It works for audio but not for video, because it doenst find any suitable video sink. I havent X running so Im looking for an OpenGL video sink. Multiple Videos in OpenGL textures in Qt 5.1, video effects with GLSL shaders. Загружено 18 января 2014.
