  • problem in loading texture from AVFrame(android)

    25 mars 2013, par SieuTruc

    I get a problem when loading data from AVFrame to openGL :

     int target_width = 320;
    
                int target_height = 240;
    
                img_convert_ctx = sws_getContext(pCodecCtx->width, pCodecCtx->height,
    
                                           pCodecCtx->pix_fmt,
    
                                           target_width, target_height, PIX_FMT_RGBA, SWS_FAST_BILINEAR,
    
                                           NULL, NULL, NULL);
    
                if(img_convert_ctx == NULL) {
    
                    LOGE("could not initialize conversion context\n");
    
                    return;
    
                }
    
                sws_scale(img_convert_ctx, (const uint8_t* const*)pFrame->data, pFrame->linesize, 0, pCodecCtx->height, pFrameRGB->data, pFrameRGB->linesize);
    
                //free(data);
    
                int line=target_width*target_height*4;
    
                data=(char*)malloc(line);
    
                if (!data)
    
                    LOGE("create data frame fail");
    
                LOGE("successful data");
    
                filldata(data,pFrameRGB,target_width,target_height);

    with function filldata as :

        static void filldata(char *data,AVFrame *pFrame,int w,int h)
    
{uint8_t *frameLine;
    
    int  yy;
    
    int i=0;
    

    
for (yy = 0; yy < h; yy++) {
    

    
frameLine = (uint8_t *)pFrame->data[0] + (yy * pFrame->linesize[0]);
    

    
int xx;
    

    
for (xx = 0; xx < w; xx++) {
    
            int in_offset = xx * 4;
    

    
data[i++] = frameLine[in_offset];
    

    
data[i++] = frameLine[in_offset+1];
    

    
data[i++] = frameLine[in_offset+2];
    

    
data[i++] = frameLine[in_offset+3];
    
        }
    
    }
    
}

    After that i use data to transfer to

    glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, *wi, *he, 0, GL_RGBA, GL_UNSIGNED_BYTE, (GLvoid*)data);

    but it cannot show texture, maybe data above and data in function gltextimage2D are different.
    Please help me figure out what is the format for gltextimage2D so i can configure data to show texture. OR anyone has some sample code to show me.

  • Redirecting FFMPEG for Android stdout and stderr messages back into a textview control

    21 août 2012, par user1545779

    With @rowntreerob's help, I have successfully built the FFMpeg for Android library / shared object for use in an Android application.

    How do I capture the stdout or stderr messages issued as a result of running an FFMpeg command and display the messages in a TexView widget in the same Android application from which the FFMpeg command was issued ?

    Also when FFMPeg connects to (Wowza/Flash Media Server)- FMS, FMS issues CONNECTING, CONNECTED and STREAMING messages. How does one capture these messages and display them using Toast in the application from from which the FFMpeg command was issued.

    Sample code will really help. TIA
