    <p>I had extract Y U V data from video frame separately and saved them in <code>data[0],data[1],data[2];</code>The frame size is <code>640*480;</code>Now I creat the <code>pixelBuffer</code> as below:</p> <pre><code>void *pYUV[3] = {data[0], data[1], data[2]}; size_t planeWidth = {640, 320, 320}; size_t planeHeight = {480, 240, 240}; size_t planeBytesPerRow = {640, 320, 320}; CVReturn renturn = CVPixelBufferCreateWithPlanarBytes(kCFAllocatorDefault, 640, 480, kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange, nil, nil, 3, pYUV, planeWidth, planeHeight, planeBytesPerRow, nil, nil, nil, &amp;_pixelBuffer); CVPixelBufferLockBaseAddress(_pixelBuffer, 0); CVPixelBufferRetain(_pixelBuffer); // Periodic texture cache flush every frame CVOpenGLESTextureCacheFlush(_textureCache, 0); // The Buffer cannot be used with OpenGL as either its size, pixelformat or attributes are not supported by OpenGL glActiveTexture(GL_TEXTURE0); CVReturn err = CVOpenGLESTextureCacheCreateTextureFromImage(kCFAllocatorDefault, _textureCache, _pixelBuffer, NULL, GL_TEXTURE_2D, GL_LUMINANCE, im.width, im.height, GL_LUMINANCE, GL_UNSIGNED_BYTE, 0, &amp;_yTexture); if (!_yTexture || err) { NSLog(@"CVOpenGLESTextureCacheCreateTextureFromImage failed (error: %d)", err); return; } glBindTexture(CVOpenGLESTextureGetTarget(_yTexture), CVOpenGLESTextureGetName(_yTexture)); CVPixelBufferUnlockBaseAddress(_pixelBuffer, 0); </code></pre> <p>But the err is -6638, the documentation simply states that "The pixel buffer is not compatible with OpenGL due to an unsupported buffer size, pixel format, or attribute." which does not help me much.</p> <p>How can I fixed it?</p>

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.
