Messages of the kaffeine session as seen by "journalctl"

Description of problem:

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.


Version-Release number of selected component (if applicable):
kaffeine-1.2.2-8.fc22.x86_64

How reproducible:
Always,
but crash appears after random number of klicks on the time scrollbar of the video

Steps to Reproduce:
1. Start kaffeine.
2. Play a video file.
3. Jump to different positions (times) in the video by klicking on different positions of the scroll bar.

Actual results:
After some klicks (not a fixed number, but mostly about between 3 and 10) the video stops playing, the screen gets black (or shows the last displayed video frame), and audio is off.
I found no way to see a video on the screen again except to terminate kaffeine and start it again.

Expected results:
Video is continuing displayed at the position where the scrollbar position represent.


Additional info:
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.

Comment 3 Edgar Hoch 2016-06-02 15:09:48 UTC
Kaffeine developers told me that kaffeine version 1.2.2 is too old (five years) and no longer supported. See the linked KDE bug report.

Fedora 22 and Fedora 23 still provides the same old version 1.2.2 of kaffeine. I think it's time to upgrade, I will file a new bug for this.
