Version: unspecified (using KDE 4.8.0) OS: Linux When downloading a large file such as a video, kio_thumbnail does not stop updating the preview until the download finishes which might take a few minutes or hours. Reproducible: Didn't try Steps to Reproduce: open dolphin and turn on preview mode go to SOME_PATH start downloading a video into SOME_PATH watch kio_thumbnail eating the cpu/memory Expected Results: If a file is being modified very quickly, reduce the preview update interval.
Thanks for the report. Dolphin only recreates the thumbnail if nothing has been downloaded for at least 2 seconds. If you use the "details view" and check the size of the file: Does the size increase periodically there?
Hi Peter, I don't think that this bug report is invalid. I'm affected by this issue as well. As you can see at the screencast, according to KDirWatch, file is written 1-3 times every second, and kio_thumbnail still generating thumbnails. http://youtu.be/NsupdEk0pnY
@gedgon: Sorry, I did not intend to set this bug as INVALID but as WAITINGFORINFO: I'd need an answer for my question in comment 1. Improvements have been done for KDE > 4.8.0 and also other improvements for the upcoming 4.9.0 version - please let me know your used KDE version too where you recorded the video.
It's KDE SC 4.8.3 on Arch Linux. Clean profile for testing purposes. kdemultimedia-ffmpegthumb for video thumbnails (it's faster and more reliable than mplayerthumbs).
Thanks!
More info, I hope it will help. In this case, video file using x264 video codec and moov atom is missing, so thumbnailer will fail every time until video file will be complete. High CPU usage and broken thumbnail will help with observations. Easy steps to reproduce: 1. play any video with "some action" without overlay and move video player window to top let corner. E.g. $mplayer -vo x11 /path/to/video/file 2. use ffmpeg to grab part of that movie. For example: $ffmpeg -an -s 640x480 -r 30 -f x11grab -i :0.0+0,0 -vcodec libx264 -y /output/path/our_video.mkv 3. $dolphin /output/path/

[Part of the Dolphin Bug Weeks 2012] I was unable to reproduce this on Dolphin 2.1/KDE SC 4.9.3 (package from the Kubuntu Updates PPA) using an OGG Theora (.ogv) video and kffmpegthumbnailer. Can you confirm that this bug still exists?
(In reply to comment #8) > I was unable to reproduce this on Dolphin 2.1/KDE SC 4.9.3 [...] Can you confirm that this bug still exists? I can't either. Looks like it's fixed.
Thanks for your feedback. Close it according to comment #8 and #9
