Messages of the kaffeine session as seen by "journalctl"

I have installed Fedora 22 and found a new problem with kaffeine:

I use kaffeine to record television dvb-c, which creates files of type m2t, MPEG transport stream data.
When I play such a file in kaffeine, and I klick on the scrollbar at the buttom of the window to jump to a different position in the video file, then after some klicks the video stops playing.
Sometimes the last displayed video frame is shown as a picture, but most times the screen is only black.

When this happens, I can start and stop playing this or other video files, they seam to be being processed, but the screen stays black and sound stays off.
When I change to the television tab, and I klick on a television channel, then the on-screen message indicating the time, channel and program information are displayed, but the screen stays black and audio stays off.
Recording of television continues.

The only solution I found is to terminate kaffeine and start it again. Then video and television is displayed normally.

I attach the messages of kaffeine in the journal.

Version: Fedora 22:
kaffeine-1.2.2-8.fc22.x86_64

I have used kaffeine with previous Fedora versions without this problem. It is new to me in Fedora 22.

Now kaffeine suddenly stops playing a video (m2t) without doing any user interaction (no key press, no mouse moving). Attached are the new messages from journalctl.

The Kaffeine version you're using is too old... it still uses the xine backend to play 
videos. We moved to libVLC sometime ago, and we just released upstream a version 2.0.1,
with is based on KDE5. So, lots of change too. 

That's said, changing the watch video position in live stream is problematic, and we
ended by disabling it in the new version, while we don't have a way to fix the issues.
The problem is that the backend player may wrongly identify a change at the play
timestamp as the end of file and stop playing. That seems to be the problem you're
reporting.

I intend to fix this on some future version. So stay tuned.

Btw, if you want to take a sneak pick on the latest version, it is at:

https://quickgit.kde.org/?p=kaffeine.git

The README file contains instructions about how to compile it.

As this BZ is on an old version that we're not maintaining anymore, I'm closing the bug. If you find similar issues with version 2.0.1, please re-open.
