 |
|
After I have upgraded my kernel from gentoo-sources-4.1.15-r1 to gentoo-sources-4..4.6 playing a 1080 mkv file with vlc the program experiences a "video stuttering" problem
If the audio track is disabled or the audio device discard all samples the bug doesn't reproduce
| Code: | vlc Game.of.ThronesS06E01.mkv
VLC media player 2.2.2 Weatherwax (revision 2.2.2-0-g6259d80)
[00007f1d9cc15f98] core input error: ES_OUT_SET_(GROUP_)PCR is called too late (pts_delay increased to 300 ms)
[00007f1d9cc15f98] core input error: ES_OUT_RESET_PCR called
[h264 @ 0x7f1d84c6a0b0] mmco: unref short failure
[00007f1d9cc15f98] core input error: ES_OUT_SET_(GROUP_)PCR is called too late (pts_delay increased to 545 ms)
[00007f1d9cc15f98] core input error: ES_OUT_RESET_PCR called

PS
gentoo-sources-4.5.3 has the same problem

| Are you using ALSA or PulseAudio? The error you're describing sounds like a buffer is exhausted (generally the case with PCR errors), and it also sounds similar to VLC bug 10422. That bug is fixed in the 3.0 branch, so if possible a good test might be to try emerging vlc-9999 and seeing if the bug is still present. If it's resolved, I can look into possibly backporting the changes (I'm the proxy-maintainer for VLC, no guarantees). If this is the approach you're open to taking, please open a bug on the Gentoo bugzilla so we can track it there (I go by the same username and will be auto-assigned VLC tickets). |

Did you find a solution? I have I think the same problem, but selecting different cards as they did in the vlc forum doesn't help.  |

The issue regarding VLC bug 10422 is already tracked in Gentoo bug 523366. A patch has also been posted in the Gentoo bug with the fix backported to VLC 2.2.x. |

| I applied the patch. It helped a bit but the stutering still occurs sometimes. (more rarely though) |

rozyk,
You may want to try the vlc-9999 ebuild since the fix was made in the 3.x branch. Otherwise try mpv, it's a great alternative to VLC. |
