What about wayland support?

[pshirshov]

baka-mplayer crashes under wayland for now while mpv itself works successfully.

[u8sand]

I'm assuming you've added the relevant Qt compilation flag; the other thing that would cause it to crash is the X11 specific code in src/platform/linux.cpp

Can you confirm that it works when you apply this patch?

Baka-mplayer now segfaults under https://github.com/SirCmpwn/Sway

@tidux did you try the patch above? The last person who used wayland didn't get back to us--I don't have a proper wayland setup to test it myself, though I will get one soon. I expect it would segfault without the patch because it is attempting to access X11 specific attributes which wouldn't be available.

[tidux]

The patch works to get the UI up and running, but the OpenGL stuff is still dependent on X, leading to a segfault when I actually try to play anything:

Note that regular mpv works 100% on this setup, so it's got to be baka-mplayer specific code rather than libmpv.

[u8sand]

@tidux You may have some luck playing with the mpv vo parameter in ~/.config/bakamplayer.ini; the default is vdpau which is X11 only. Some things that might work are opengl (safest option) or vaapi (intel va api), there is also a vo called wayland maybe that's what you need.

...

    "mpv": {
...
        "vo": "wayland",
...
    },
...

You can also try removing the vo option to have mpv autoselect (I hope, maybe baka will just put it back though, you can also try making it empty string). Do tell me if any of these things work.

I use i3 myself so I may try setting up Sway.

[tidux]

vo = opengl crashes again. vo = wayland causes a new empty region (not even blank, just the wallpaper) to work although audio does play. I'm seeing similar behavior for vo = wayland on raw mpv (vo = opengl works there) so it may be a Sway bug.

[u8sand]

@tidux sounds like maybe the vo driver is working properly but passing the win handle to mpv isn't (hence why you aren't seeing anything). I have a feeling this might end up working properly when we use opengl-cb; I'll keep you up to date on if I can get it working on my side. Thanks for trying those things out

[u8sand]

@tidux I installed sway on my system and got it running by making vo a blank string, I was able to watch a video. I'm using archlinux, noveau early KMS, and baka-mplayer-git

[tidux]

I'm using baka-mplayer from git master, Arch, and Intel drivers. That just crashes for me.

I can't execute baka-mplayer on Wayland, it crashes:

[u8sand]

Please confirm whether or not mpv crashes on Wayland. Or Wayland support would be solely dependent on qt's (which I implemented in the patch) and mpv's (which should be an issue on their repo)

In fact I found this on mpv:

gpu-context=wayland

Put that in the mpv options of bakamplayer.ini and it may just work.

Though it's strange because Wayland was working for me a while back. Also make sure you have Qt-Wayland installed for qt's Wayland support

mpv works well.

[mufeedali]

Any progress on this? mpv does work perfectly on Wayland now. By now, KDE's Wayland support is also pretty good. So, it would be cool to have Baka-MPlayer working too.

[ranenvious]

I don't know if it's unrelated or not (given this thread was last active in 2019) but I am also getting a segmentation fault when running it on an about 3 week old EndeavourOS install that is up to date. If I install the AUR git variant it at least launches, but doesn't seem to play anything ( sometimes I do get audio though )
