SMPlayer Support Forum

I am running smplayer-portable with mpv on Win 7 in a Pentium Dual Core and it works fine (I can watch youtube videos with subtitles at 1080p), unfortunately it does not work in an older Pentium 4 @ 2.4 Ghz with Windows XP sp3.
I also tried to run only mpv; I've tested some new and old win32 builds from http://mpv.srsfckn.biz/ , with no success, so the problem is mpv, not smplayer, also smplayer with mplayer works fine with this xp machine.
I don't know if it's a hardware or software issue.
Which are the system requirements for smplayer with mpv?

Hi rvm,

I installed smplayer with option for mpv in a computer with xp , but when i tried to watch video files in my computer or try to watch youtube,vimeo videos, i hear the sound,time frame is working nicely , but the screen is black, there is no video(Installation process automatically selects opengl video driver) . I manually choose different output drivers after the installation ( in preference -video) like ,direct3d/x image, direct 3d shaders ,default , and etc and in some cases , for example when directx is chosen ,video image shows and freezes , time frame is staggering. and in other cases , smplayer doesn't start.I, also, try combining different youtube playback qualities with different video drivers,but it still freezes .
When I install smplayer with mp4 , there is not such a problem, when opengl video driver is selected ( as it is automatically chosen by the installation ) ,everything is fine .
Does the problem come from the computer , from the xp, or should i expect a fix in some of the future releases of smplayer with mpv regarding output video driver ?

thank you in advanced !

What video card do you have? Only thing I can think of is to make sure you have the latest driver for that.

MPV focuses more on supporting newer hardware and removing legacy support I don't believe they will be much help or willing to fix anything for systems as old as that.

I asked at mpv mailing list and they confirmed XP is supported and system requirements are "graphics drivers at least for Direct3D 9, or OpenGL"
Finally, I could make mpv and smplayer+mpv work on this XP computer.
For standalone mpv I launched it with some command lines to force direct3d driver:
mpv.exe --vo=direct3d --force-window --idle
For SMPlayer+mpv I selected direct3d as output driver.
For some reason, smplayer was passing "directx" defined by user as default which caused mpv to freeze.
