    <p>I'm trying to render AV frames grabbed and converted from a MPEG4 video using Gstreamer to an Android (2.2)-opengl texture. I've pretty much exhausted google and not found an answer. </p> <p>Basically, I am using Gstreamer uridecodebin to decode the frame, and then convert the frame to RGB, and then <code>glTexSubImage2D()</code> to create an openGL texture from it, but can't seem to get anything to work.The texture is getting colored when I get the decoded data (RGB) from Gstreamer.</p> <p>I am getting the video size as <code>320 * 256</code> and my Texture size is <code>512 * 256</code> &amp; I am using <code>glDrawTexiOES(0,0,videowidth,videoheight)</code>, I am not getting any errors related to opengl, but the texture is blank( different color frames), though the Audio works fine.</p> <p>Here is my code:Native OnDraw:</p> <pre><code>if (theGStPixelBuffer != 0) { glBindTexture (GL_TEXTURE_2D, s_texture); glTexParameteri (GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT); glTexParameteri (GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT); glTexParameteri (GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexParameteri (GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glPixelStorei( GL_UNPACK_ALIGNMENT, 2); glTexSubImage2D (GL_TEXTURE_2D, 0, 0, 0, theTexWidth, theTexHeight, GL_RGB, GL_UNSIGNED_BYTE, GST_BUFFER_DATA(theGStPixelBuffer)); check_gl_error("glTexSubImage2D"); theGStPixelBuffer = 0; } glDrawTexiOES(0, 0, 0, theTexWidth, theTexHeight); check_gl_error("glDrawTexiOES") </code></pre>

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.
