I've got a working KDE with sound and VLC installed on my raspberry pi 2, but I don't have hardware acceleration yet. I've installed VLC with these use flags:
| Code: | rpi2 ~ # emerge -pv vlc
These are the packages that would be merged, in order:
Calculating dependencies... done!

Total: 1 package (1 reinstall), Size of downloads: 0 KiB |
I have also changed the video output in vlc to "OpenMAX IL video output" but it still seems the video is being decoded by the cpu.
How do I enable accelerated video? |

At least in the 2.1 series you would have to pass --enable-rpi-omxil - USE=omxil probably passes --enable-omxil, but rpi stack isn't generic enough (i.e there's no good X GL integration unless playing with the new VC4 mesa drivers, so everything needs their own rpi specific initialization sequence) - it seems to be the case with OMX as well, which seems logical as there are many RPi specifics in the gstreamer stack for this as well (with which I'm more intimately familiar). Probably related to dispmanx usage and the likes. So you'll need to find or make an ebuild that passes that instead or as well (not sure how it wants it). Maybe the arm overlay or some other overlay out there already has something like this. Additionally stuff like this ought to enter main tree as well imho - maybe I can help with that in the future, but currently my RPis are far away from me.
I found this by running "ebuild <ebuild file> prepare" on vlc and then going to the prepared location in my PORTAGE_TMPDIR and running ./configure --help |less to see the options easily. The specific needs and dependencies can probably be found by reading configure.ac source file, which might require some autotools knowledge.
