I get a problem when loading data from AVFrame to openGL: <pre><code> 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); </code></pre> with function filldata as: <pre><code> 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]; } } } </code></pre> After that i use data to transfer to <pre><code>glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, *wi, *he, 0, GL_RGBA, GL_UNSIGNED_BYTE, (GLvoid*)data); </code></pre> 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.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
