Border artifact in simple pipelines.
Last modified: 2017-10-07 12:43:23 UTC
Created attachment 361081 [details] Output with -v flag and GST_DEBUG=xvimage*:6 Simple video pipelines render with a 1px green border around the entire image. I have seen this with the following two pipelines: gst-launch-1.0 filesrc location=/ram/test.mkv ! decodebin ! videoconvert ! xvimagesink gst-launch-1.0 -v playbin uri="file:///ram/test.mkv" Adding a videocrop element to the pipeline avoids the issue. Even if I only crop one side, the border disapears on all 4 (cropping 0 sides leaves the border): gst-launch-1.0 filesrc location=/ram/test.mkv ! decodebin ! videoconvert ! videocrop left=1 ! xvimagesink The border is generally green, but will switch to being multi-colored with no pattern that I have noticed.
Created attachment 361082 [details] Screenshot My screenshot software failed to caputure the artifact at the top and bottom of the video (which as also the top and bottom of the window). Despite this, the artifact was visible at the top and bottom as well.
