    <p>I am writing an app to make an MJPEG-Stream from the iPhone to the Server. My problem is that the JPEG's I see are a weird collection of colored lines. I can post the specific code if more information is needed.</p> <p>These are the Steps:</p> <ol> <li>Get the frames via <code>AVCaptureVideoDataOutput</code></li> <li>Convert them to an <code>UIImage</code></li> <li>Get <code>NSData</code> <code>UIImageJPEGRepresentation()</code> from it</li> <li>Make an <code>NSMutableData</code> and wrap the Image with "Content-Type: image/jpeg" and --BOUNDARY</li> </ol> <p>Now i want to send them as UDP Packets to my server. I use asyncudpsocket on the iPhone and a small java datagrammserver on the PC.The first problem is the mtu. Asyncudpsocket says message too long if the <code>nsdata</code> is larger than 9kb. Therefore:</p> <ol> <li>Split the image into 9kb chunks</li> <li>Send them with asyncudp socket</li> <li>Accept an TCP Socket on port 2020 on the PC</li> <li>Receive the DatagrammPackets and stream them to the connected TCP Socket</li> <li>Open Firefox with localhost:2020 and watch the MJPEG</li> </ol> <p>I've tested each part seperated and can tell that they're okay. I can show the images in a <code>UIImageView</code>, I can send, receive and show the bytes from the socket and I can stream JPEG's over a serversocket and watch them in Firefox.</p> <p>The image fits in one datagrammpacket if they're small enough (that's sometimes the case), and I can see the header, bytes and the boundary.. but why is my MJPEG stream still showing me a weird colored image (instead of a black or white image, which should be the case)?</p>

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.
