Description Jakub Steiner 2013-03-18 17:04:23 UTC 
When encoding videos from PNG sequences in gnome-getting-started-docs, I get a green bar on the right hand side*. The pipeline used on 1280x720 PNGs is:

"gst-launch-1.0 webmmux name=mux ! filesink location=\"%s/%s\"    file://%s ! decodebin ! audioconvert ! vorbisenc bitrate=96000 ! mux.     multifilesrc location=\"%s/%%04d.png\" index=1 caps=\"image/png,framerate=\(fraction\)24/1\" ! pngdec ! videoconvert ! videoscale ! video/x-raw, width=854,height=480 ! videorate ! vp8enc threads=12 target-bitrate=200000 ! mux." % (transcodepath,webmfile,sndfile,framepath)


This is gstreamer1 on Fedora 18.

I do not seem to be able to reproduce the issue with these commands on GStreamer 1.2.0:

gst-launch-1.0 videotestsrc num-buffers=50 ! video/x-raw,width=1280,height=720 ! pngenc ! multifilesink location=file_%02d.png

gst-launch-1.0 multifilesrc location=file_%02d.png caps="image/png,framerate=24/1" ! pngdec ! videoconvert ! videoscale ! video/x-raw,width=854,height=480 ! vp8enc threads=12 target-bitrate=200000 ! webmmux ! filesink location=out.webm

Jakub do these commands still show your problem on Fedora 18?

It seems to have been fixed in the meantime. I no longer see any artifacts in fedora 20.
