You are a bit light on the details. Maybe start reading the GStreamer application development manual. How to capture from your IP camera, depends on the camera. If it offers rtsp you can use the 'rtspsrc' element, otherwise you might need other elements. Start capturing data, then depayload and remux to a matroska/mpeg-ts/whatever file. Then you can add a subtitle track with the 'appsrc' element, by pushing data into the pipeline from your app.</div> <div><br> </div> <div><br> </div> <blockquote style='border-left:2px solid #CCCCCC;padding:0 1em' style="border-left:2px solid #CCCCCC;padding:0 1em" type="cite"> <div id="divtagdefaultwrapper" style="font-size:12pt;color:#000000;background-color:#FFFFFF;font-family:Calibri,Arial,Helvetica,sans-serif;"> <p>Do you have also something to say about other information, i provided to you?</p> </div> </blockquote> <div><br> </div> <div>Not really.
