Multithreaded video.
Is there any video player that takes advantage of multithread? As my Nvidia card is not useful under OpenBSD (so I have to use X11 output), I would like to play video using more cores. I tried mplayer/smplayer to not avail, only one thread is used and hence the resolution is limited and full screen is painful.
I tried to re-encode the video to H264 through mencoder, and it did it using multithread, but mplayer did not used it when playing the re-encoded video. Am I missing something or is it just impossible? |

First of all, did you install the bsd.mp kernel ?
See OpenBSD FAQ 8.12 - SMP. Edit : and I think VLC is a multi-threaded decoder since version 2.0

Yes, I installed OpenBSD on a multiprocessor machine and I can see the processors up to CPU7 going online at boot time.
VLC hangs. Code:
OpenBSD asuka.familyworks.local 5.3 GENERIC.MP#3 amd64 |

Please provide the complete output of dmesg(8).

OK, here it goes.

Resolution won't have anything to do with the number of cores you use or have. It's entirely a function of the display, graphics hardware, and the OS's video driver. Since you're apparently using the VESA driver, you're limited to VESA resolutions.
Your Nvidia GTX 260 is apparently not supported by the nv(4) driver, which is the only other possible solution for Nvidia graphics on OpenBSD. The graphics card is not in OpenBSD's table of known PCI devices, either: Code:
vga1 at pci2 dev 0 function 0 vendor "NVIDIA", unknown product 0x05e2 rev 0xa1 Last edited by jggimi; 1st July 2013 at 03:56 PM. Reason: clarity, typo |

Well, I see in top that what uses more CPU cycles is Xorg.
So I am Xorg limited because of my Nvidia graphics card Last edited by Martillo; 4th July 2013 at 12:46 PM. |
