It seems that '--avcodec-threads 20' option solves the problem. The solution is found here: https://wiki.videolan.org/WindowsFAQ-2. ... r_laggy.29

Is it intended behaviour that I have to set that option manually?

I'm using VLC media player 2.2.2 Weatherwax on Centos 7 x64 and having problem with a 4K video playback. VLC playe lags heavily and almost freezes when playing the video file, although ffplay does not have any problems with it. Also I have the same problem on Windows with VLC player 2.1.3 and 2.2.4....

I set it just like standard values:

And what is the main difference between setting standard and custom aspect ratio? Why do changes apply on the fly for standard values and do not for custom values?

Is it possible to change aspect ratio to some custom value dynamically using libvlc_video_set_aspect_ratio? Ideally I would like to set the same aspect ratio as the player window has on its resize. Currently I can onle change aspect ratio to some standard values like '1:1' or '4:3'. Setting a custom...

What is the difference between these two parameters: "--no-audio" and "--aout=none"?
On my system I have some problems with files playback over HTTP when I use the first parameter, and the problem disappears when I use the second one instead.

I want to display some text over the video. First I try to do it using the VLC player. As this manual says, I launch the player this way: vlc --sub-filter=marq --marq-marquee="Obvious Watermark" --marq-position=0 --marq-size=50 somevideo.avi In this case everything works fine. Then I try t...

I'm using the logo module to show some image over video. Currently the displayed image size depends on the video resolution and the size of the player window.
Is it possible to display an image with fixed size?

I've built VLC media player 1.1.13 from sources and now I'm trying to launch it under some special version of Centos 5. The problem is that I can't see the video when I try to open some media files, I just get the black screen. Here's the log: VLC media player 1.1.13 The Luggage (revision exported) ...

I use nginx-rtmp-module to create a simple video on demand service. I can play my videos in VLC player by opening urls like this: rtmp://127.0.0.1/vod/movie.flv Also I can play those videos using JW Player as a flash player inside a web page. The problem is that seeking doesn't work in VLC player. I...

I use VLC 2.1.1 under CentOS 6.2 x64.
I'm trying to convert some videos to mp3 using VLC Media Player but resulting files contain only loud noise.
I've tried different source files with mp2 and Vorbis audio but had no success.

What is the problem with converting to mp3 using VLC Player?

libvlc_media_player has these two functions for playback control: libvlc_media_player_set_position and libvlc_media_player_set_time.
What is the difference between them? Do they internally work the same way? Is one of them more accurate than another?

In my app I init a libvlc object with no arguments. Then I start playback, set the volume to some value and then close my program. Next time I open my program and start the playback, it starts with the same volume I set previous time. I tried libvlc_audio_set_volume(vlcPlayer, 100) before playback s...

Also there's a weird thing that, if I don't mute the first player, the second player starts with exactly the same volume as the first one had.

Ok, I'll try. So, you confrim that proper way is 'one libvlc object = one player'? I ask because in another part of my app I have a player playing in one tab, then user can switch to another tab (the first player becomes mute) and start the second player. In this case everything works fine with a si...

I'd like to know the proper way of having two media players working in parallel. Do I need to create two vlc instance objects for them? Or they can share a single one? I my program I need to have two players working at the same time. In the begining only one player is playing, but user can open anot...

The only two flags passed by VLC 2.0.x to libvlc_new() are --no-ignore-config and --media-library. They are likely irrelevant in this case. If I use these flags and have no other errors in my program, I should get exactly the same behaviour as in Vlc Media Player, right? I mean these functions will...

Hi. I'm using libVLC 2.0.5 (vlc-qt actually) to create a media player for my program. I have some problems with sound output: there are notable lags on volume changing and I have no sound at all when I pause and then resume the playback. I have these problems both on Linux and Windows, but Vlc Media...

Hello again. I'm using libvlc in my program for playing video files. And I need to know actual size of the video window. I can use libvlc_video_get_size to do this, but some files have sar (sample aspect ratio) not equal to 1. I mean I can use that get_size function but I won't get the correct actua...

I've tried this, but it didn't work. I've created an event manager for my player to wait for libvlc_MediaPlayerVout event: libvlc_event_manager_t *managerPlayer = libvlc_media_player_event_manager(mediaPlayer); libvlc_event_attach(managerPlayer, libvlc_MediaPlayerVout, &getSize, mediaPlayer); Wh...

Hello. I'm using the following functions to get video resolution: libvlc_media_parse(m_media); libvlc_video_get_size(m_player, 0, &x, &y) This works with .flv videos but doesn't work with .mpg ones. I've tried to look inside the ' libvlc_video_get_size ' function and saw that ' libvlc_media_...
