I think what you describe is not a frozen image but a way to inform the receiver that smth is wrong with the input.<div>The image is streamed so the data comes in all the time. The only way is to detect a blue screen by analysis of the image ( histogram maybe)<br>
<div>If you expect a ready plugin for detection a blue image I doubt there is smth like that.</div><div>Maybe <span class="Apple-style-span" style="font-family: 'Times New Roman'; font-size: medium; ">frei0r-filter-g (-r,-b) would help. But I don't have any experience with that.</span><br>

Hi,<br><br>I'm developing an application that uses GStreamer to play video streams using RTSP.<br><br>The RTSP server is an off-the-shelf board that streams MJPEG video from analogue cameras.<br><br>If a camera is unplugged this board streams a still blue image. And I need to be able to detect it.<br>
<br>I found out a plugin called <i>imagefreeze</i> that creates a stream from an image file. But what I want is a plugin that detects a frozen video stream.<br><br>Would anyone know a plugin with similar functionality? Is anyone developing something similar?<br>
<br><br>Thanks in advance,<br><font color="#888888"><br>Thierry<br>
