[SOLVED] vlc --vout=caca fails in Wayland DE but works in tty

Running on GNOME 50 wayland, running vlc with caca output fails with:

$ vlc --vout=caca video.mp4 (or even with cvlc)

I wonder if there's any pkg I missed that provides what vlc needs. Same command works when in a tty though.

caca = Ascii Art ?

Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.

Have you tried running

$ QT_QPA_PLATFORM=wayland vlc --vout=caca video.mp4

?

You do have https://archlinux.org/packages/extra/x8 … ugin-caca/ ?
Does VLC play w/ "normal" outputs codecs?

No, I mean whether VLC plays video when *not* using CACA but regular, normal pixels.

Re: [SOLVED] vlc --vout=caca fails in Wayland DE but works in tty

Can https://archlinux.org/packages/extra/x86_64/mplayer/  play using libcaca?
(Iirc it will unconditionally run on xwayland, though)

Yes but in very low resolution windowed and weird colours, even with -fs. It runs fullscreen in tty but in a very glitchy way.

Re: [SOLVED] vlc --vout=caca fails in Wayland DE but works in tty

Tried with mpv which should have caca support if I remember right, it also reports:

 mpv --vo=caca video.mp4
● Video  --vid=1  (h264 1920x820 23.976 fps) [default]
● Audio  --aid=1  (aac 2ch 48000 Hz 96 kbps) [default]
[vo] Video output caca not found!
Error opening/initializing the selected video_out (--vo) device.
Video: no video
AO: [pipewire] 48000Hz stereo 2ch floatp

Re: [SOLVED] vlc --vout=caca fails in Wayland DE but works in tty

[vo] Video output caca not found!

mpv doesn't provide caca

mpv -vo=help

Yes but in very low resolution windowed and weird colours, even with -fs. It runs fullscreen in tty but in a very glitchy way.

Does caca work as expected on
1. Xorg (try an openbox session)
2. not gnome (weston, labwc, hyprland, niri, kwin_wayland,… pick one)

Re: [SOLVED] vlc --vout=caca fails in Wayland DE but works in tty

mplayer -vo caca video.webm is still glitchy in tty, but it works in xorg, just in black and white for some reason.

EDIT: cacademo works both in wayland and xorg.

Re: [SOLVED] vlc --vout=caca fails in Wayland DE but works in tty

https://code.videolan.org/videolan/vlc/ … tems/18104
This is ten years old but the gist is that vlc+caca only works on the console… (and you must esp. not set CACA_DRIVER)
ctrl+alt+f3, login, try - does it work there?

Re: [SOLVED] vlc --vout=caca fails in Wayland DE but works in tty

I've said that it works on the tty. I guess then this is normal behavior, I guess it'd have been better for a message from VLC that would tell us of this instead of just giving out an error. Thank you so much for your help both of you, I appreciate it! Marking as solved.
