android - Record opengl fbo made with c++ with java MediaCodec -

-

i'm trying record contents of fbo create , fill in c++ mediacodec java object.

i understand need surface mediacodec , draw on frag shader, i'm trying feed c++ fbo uniform shader.

at moment can write video , if draw pixels red shader got red clip, ok on shader=>surface=>mediacodec side.

to use fbo i'm passing glunit of texture of fbo java side jni function, , seems ok, got noise, not initializated texture.

so question is: in way possible use texture done c++ input uniform gles2 java shader?

and if yes, correct flow so?

to clarify, i'm doing in glsurfaceview.renderer class:

@override public void onsurfacecreated(gl10 gl, eglconfig config) {     log.i("of","onsurfacecreated");     ofandroid.onsurfacecreated();     try{         ((ofactivity)ofandroid.getcontext()).onglsurfacecreated();     }catch(exception e){         log.e("of","couldn call onglsurfacecreated",e);     }     return; }  @override public void onsurfacechanged(gl10 gl, int w, int h) {     this.w = w;     this.h = h;     if(!setup && ofandroid.unpackingdone){         try {             setup();         } catch (ioexception e) {             e.printstacktrace();         }     }     ofgesturelistener.swipe_min_distance = (int)(math.max(w, h)*.04);     ofgesturelistener.swipe_max_distance = (int)(math.max(w, h)*.6);     ofandroid.resize(w, h);      mrenderfbo = new renderfbo(             800, 800, msrftexid);     mfbotexid = mrenderfbo.getfbotexid();      glutil.checkglerror("onsurfacecreated_e");  }  @override public void ondrawframe(gl10 gl) {     if(setup && ofandroid.unpackingdone){         ofandroid.render();          if (mrendersrftex != null) {             mrendersrftex.draw();         }         glutil.checkglerror("ondrawframe_e render srf tex");     }else if(!setup && ofandroid.unpackingdone){         try {             setup();         } catch (ioexception e) {             e.printstacktrace();         }     }else{         gl.glclear(gl10.gl_color_buffer_bit);         gl.glclearcolor(.5f, .5f, .5f, 1.f);         } }  public void setrecorder(myrecorder recorder, int mytexid) {     texid = mytexid;     synchronized(this) {         if (recorder != null) {             mrendersrftex = new rendersrftex(                     800, 804,                     mytexid, recorder);         } else {             mrendersrftex = null;         }     } }

where mytexid gluint pass c++ java jni, containing gluint of fbo texture.

for reference classes myrecorder , rendersrftex see classes @ https://github.com/morihirosoft/android_mediacodectest/tree/master/mediacodectest18/src/jp/morihirosoft/mediacodectest18

and here sources of relevant part of framework, https://github.com/openframeworks/openframeworks/blob/master/addons/ofxandroid/ofandroidlib/src/cc/openframeworks/ofandroidwindow.java

the answer absolutely yes, it's possible pass via gluint textureid c++ java, , here there solution record openframeworks offbo mediacodec https://github.com/rcavazza/openframework-android-recording. fadden useful answers.

i've created components , helper methods using c++ , qt used in qml gui. of methods calculate gui elements (size, transformations, scene graph items creation). target arm 32 bit using opengl / eglfs render output. opengl using float , qml using real (defined double ). what should use in c++ do not lose precision? if use qreal ( double ) shouldn't lose precision. if git grep float in qtbase.git , can find out bit more: dist/changes-5.2.0-**************************************************************************** dist/changes-5.2.0-* important behavior changes * dist/changes-5.2.0-**************************************************************************** dist/changes-5.2.0- dist/changes-5.2.0- - qt compiled qreal typedef'ed double on dist/changes-5.2.0: platforms. qreal float on arm chipsets before. guarantees more dist/changes-5.2.0- consistent behavior between platforms qt supports, binary dist/chan...
