(mpv)(osx lion;macmini2.1)-(only audio, no video output)

[mrkapqa]

Hello ,

after failing to install MPV on my Powermac G5 i finally got the opportunity to try it on macmini 2.1 with Intel Graphics 945. The build seemed to compile just fine, many thanks for this awesome work!

Only, found out that it does not play any video, just giving audio feedback.

Can you please help me with the MPV options to override this. Macmini 2.1 gives only OpenGL 1.4 i think, whereas 2.1 is required to work with MPV.

here is an output i get when playing video

Sorry, this is not something you or I could fix.

The situation goes like that: mpv is only supported on 10.8 or higher. I have written a patchset to make it work (barely) on at least 10.7 and 10.6 (maybe even 10.5 - haven't tested that far back.)

The obvious caveat is that for some reason the video output fails to initialize properly and nothing will play via the Cocoa backend. The OS X-internal libraries spit out something like "invalid pixel format", but I have no idea how to fix that.

There is a workaround, though. If you can live with video playback via X11, consider using the +x11 variant. It should be enabled by default.

Try executing mpv as such:

mpv -vo=opengl:backend=x11 file

This should give you video playback over X11 with OpenGL. If it works, you may want to tweak your ~/.mpv/config file. It's inconvenient, I know, but so are most workarounds...
