VLC terminal output, both stdout and stderr

On VLC when I play MPEG2-TS or MPEG4-TS file and move backwards on the video I don't get any sound and lines like this are printed to terminal:
[00007fcec0e6a3a8] core decoder error: Could not convert timestamp 16479796757
[00007fcec0e6a3a8] core decoder error: Could not convert timestamp 16479820757
[00007fcec0e6a3a8] core decoder error: Could not convert timestamp 16479844757
[00007fcec0e6a3a8] core decoder error: Could not convert timestamp 16479868757
[00007fcec0e6a3a8] core decoder error: Could not convert timestamp 16479892757
[00007fcec0e6a3a8] core decoder error: Could not convert timestamp 16479916757
then when I move forwards the sound comes back and those lines won't be printed anymore. 

Steps to Reproduce:
1. Play a TS file on VLC
2. Move backwards (I used mouse to click the bar)

Actual Results: 
No sound and a lot of error messages like described above printed to terminal. Full terminal output added as an attachment. 

Expected Results:
The file plays normally with no unexpected terminal output and with sound.

My System:
I'm using Fedora 21 with VLC version 2.2.0 release 0.2.fc21 (x86_64). I tested that using software instead of VDPAU (on radeon driver on HD6650) that I normally use doesn't make any difference. If there is something else I should tell you about my system feel free to ask.

Additional Information:
The TS files are captured from Finnish digital television signal (DVB-C or DVB-T/T2, I wouldn't know which) on Elisa Viihde service. Later I may be able to test this with something I captured from DVB-T signal with MythTV but that probably has the same results. Anyway I don't hold copyright to any of that content and I don't think I'm able to share any of it for others to test with. I tested that this problem doesn't happen on a flv file that I happened to have on my disk.

Can you reproduce with current vlc ?
Do you have reported the issue upstream ? (if not please do so).
Comment 2 Tomi Leppänen 2015-04-27 21:37:01 CEST
I can't reproduce this anymore with vlc 2.2.1-2.fc21.
