  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

    My problem is that when i have split one video with equal length by -ss and -t ffmpeg command then in all chunk’s audio are drifts(means only audio play well but video display after 2 or 3 seconds - means video is paused or async). I want to resolve splitted videos audio/video sync problem.

    Can anybody help me to resolve this kind of issue ?

  • 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.
