Picture Seetings
Locked

Hi All,
Is there a command to the GStreamer open the video window where I want? You can also change the resolution? Example: Opening a Camera in the upper left in Resoulçao 600x800, open Camera 2 on the Bottom at 000x000 resolution. Thank you! |

I need to open the image from the camera at any resolution, and also want to know how I can move the image, example: put running on the top right, and appears this error, can someone help me?
gst-launch ksvideosrc device-index=0 ! video/x-raw-rgb, width=1024, height=720 ! directdrawsink I tried also gst-launch ksvideosrc device-index=0 ! video/x-raw-rgb, width=1024, height=720 ! dshowvideosink Seeting Pipeline to Paused . . . ERROR : Pipeline doesn't want Pause. ERROR : from element /GstPipeline:pipeline0/GstKsVideoSrc:ksvideosrc0: Could not negotiate format Addictional debug info : ..\..\..\Source\gstreamer\libs\gst\base\gstbasesrc.c(2719): gst_base_src_start(): /GstPipeline:pipeline0/GstKsVideoSrc:ksvideosrc0 Check your filtered caps, if any Seeting pipeline to Null . . . Freeing Pipeline . . . |

Are you sure that the camera/driver supports RGB output? What do these commands output: gst-launch-0.10 -v ksvideosrc device-index=0 ! fakesink gst-launch-0.10 -v ksvideosrc device-index=0 ! video/x-raw-rgb ! fakesink gst-launch-0.10 -v ksvideosrc device-index=0 ! video/x-raw-rgb,width=1024 ! fakesink gst-launch-0.10 -v ksvideosrc device-index=0 ! video/x-raw-rgb,width=1024,height=720 ! fakesink gst-launch-0.10 -v ksvideosrc device-index=0 ! video/x-raw-yuv ! fakesink gst-launch-0.10 -v ksvideosrc device-index=0 ! video/x-raw-yuv ! fakesink gst-launch-0.10 -v ksvideosrc device-index=0 ! video/jpeg ! fakesink gst-launch-0.10 -v ksvideosrc device-index=0 ! video/x-dv ! fakesink Also: have you tried adding ffmpegcolorspace ! videoscale in front of your video sinks?

i worked very little with video... on windows even less :-). But you could try ffmpegcolorspace: http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-plugins/html/gst-plugins-base-plugins-ffmpegcolorspace.html like this: gst-launch -v ksvideosrc device-index=0 ! video/x-raw-rgb, width=1024, height=720 ! ffmpegcolorspace ! directdrawsink hope this helps. Best regards, Katcipis
