Screen capture high CPU load
Locked
 
|
Hello Iam trying to do some screen capture and send via udp(windows)
pipeline for example. dx9screencapsrc monitor=0 ! videoconvert ! x264enc ! rtph264pay ! udpsink host=127.0.0.1 port=5004 pipeline are working but it loads cpu up to 40% with openh264enc it works much better x9screencapsrc ! videoconvert ! openh264enc complexity=0 usage-type=0 bitrate =500000 ! rtph264pay ! udpsink host=127.0.0.1 port=5004 loads cpu up to 15% I need 4 like this for 4 monitors I see that dx9screencapsrc output format BGR, so I need videoconvert before x264enc or openh264enc (don't recieves BGR). So my question is there some practices to make this script works better? Newer version of gstreamer(I am using 1.8.0) works better? Thank you for advices! -- Sent from: http://gstreamer-devel.966125.n4.nabble.com/ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

Hello,
I do the same, thats a normal performance with this load. I have about 50 to 60% cpu load with full hd.
Do you use windows or Linux?

Windows. After some tests with videotestsrc and fakesink I sink that encoding to h264 it is heavy operation. So I can't reach normal cpu load with this scripts and better to buy h264 hardware encoder? On Fri, Aug 3, 2018, 02:34 P S <[hidden email]> wrote:

In reply to this post by BogdanS
can you try x264enc speed-preset=ultrafast or x264enc speed-preset=veryfast x264enc has default preset of medium.
