<div dir="ltr"><div><div>I have a Linux application where we want to capture a live HTML5 browser session and stream the results through gstreamer to a 4K projector. Because of the size the final results will be shown at, we would like to do the capture at 4K resolution, rather than upscale it for projection.<br>
<br></div>We have the back-end working fine: if we feed in a canned capture of a 4K session, we can stream and project it fine. However, we can't seem to do a capture in realtime. I'm hoping its just because we took the naive approach of setting up a dummy Xorg session (we don't have any 4K video cards), and launched Mozilla on it. We then used ximagesrc to capture from the Xorg session into gstreamer. The results were FAR too slow to be usable.<br>
<br></div>I was hoping someone here would have some suggestions as to things we could do to capture and stream more efficiently.<br clear="all"><div><div><div><br>-- <br>Stirling Westrup<br>Programmer, Entrepreneur.<br><a href="https://www.linkedin.com/e/fpf/77228" target="_blank">https://www.linkedin.com/e/fpf/77228</a><br>
