[vlc] Smooth in mplayer, choppy in vlc

[Grant]

My camera produces 1080p 60fps videos which play back choppy on
mplayer and vlc on my Dell XPS13 laptop. If I use -lavdopts threads=4
with mplayer, playback is smooth. I tried increasing ffmpeg threads
from 0 to 4 in the vlc settings but playback is still choppy. I'm
also curious if vaapi should be negating the need for threads in vlc.

I suggest you enable hardware acceleration.

My results are the same with 'vlc --avcodec-hw=vaapi'.

Maybe the video output drive? XV, OpenGL etc...

I'm having this issue even with the latest vlc from git. Any ideas?

You're right, I tried a 1080p Blu-Ray rip and it is also choppy with
audio enabled and smooth with audio disabled. mplayer plays both the
Blu-Ray rip and the 60fps file smoothly. I fiddled with the vlc audio
settings to no avail. Do you know how to fix this?

mplayer is probably using alsa, and VLC is using pulseaudio. Try
switching the audio output between alsa and pulse in VLC.

I'm on Gentoo and I don't have pulseaudio installed. I've tried
designating ALSA specifically in the vlc settings but performance is
still choppy.

What's your version of VLC?

Anything you've done in a/52 preference in VLC (in all

Since when did this start to happen? What's you're version of

What's your version of VLC?

I've tried 2.1.2 and 9999 (latest from git).

Anything you've done in a/52 preference in VLC (in all
preferences>audio/video codec>a/52)?

I've tried with and without dynamic range compression and the internal
upmixer. No other options there.

Since when did this start to happen? What's you're version of
media-libs/a52dec?

Previously, I didn't usually play videos on this system so it may have
been happening for a while. It wasn't happening about a year or so
ago. I've tried a52dec-0.7.4-r6 and 0.7.4-r7.

I just noticed that every time it stutters I get this in the console:

core input error: ES_OUT_SET_(GROUP_)PCR is called too late
(pts_delay increased to 300 ms)
core input error: ES_OUT_RESET_PCR called

You're right, I tried a 1080p Blu-Ray rip and it is also choppy with
audio enabled and smooth with audio disabled. mplayer plays both the
Blu-Ray rip and the 60fps file smoothly. I fiddled with the vlc audio
settings to no avail. Do you know how to fix this?

mplayer is probably using alsa, and VLC is using pulseaudio. Try switching
the audio output between alsa and pulse in VLC.

I'm on Gentoo and I don't have pulseaudio installed. I've tried
designating ALSA specifically in the vlc settings but performance is
still choppy.

Did you try and play just pure AAC audio? It could be an a/v sync issue.

I'm not sure how to get ahold of a sample like that. Do you know of
one available online?

It's worth mentioning that the problem also doesn't exhibit itself with mpv.
