"Use GPU accelerated decoding" option is greyed out
Posted: 29 Apr 2012 16:01
I swapped an MX440 (64 mb) video card for an Evga GeForce 6200 (256 mb) video card because VLC can't really play large h.264 video files smoothly on my system.
I updated VLC to the latest version (2.0.1 I think) but I was still seeing this issue with version 2.0.0.
This chart:
http://www.nvidia.com/docs/CP/11036/Pur ... arison.pdf
indicates that the AGP version of GeForce 6200 has H.264 decode acceleration for both Hi-def and standard-def content (but it doesn't have H.264 decode with IDCT and CAVLC/CABAC - what ever the hell those are). It also has MPEG-2 decode acceleration, but not Mpeg-2 inverse telecine (what-ever that is).
VLC has a check-box to enable "Accelerated video output (overlay)" - and I have that checked.
VLC also has (in the Input & Codecs settings section) a check-box for "Use GPU accelerated decoding" - but that option is greyed out. Any idea why?
I was trying to play a video file with these specifications:
Codec ID : V_MPEG4/ISO/AVC
Bit rate : 3550 Kbps
Width : 1280 pixels
Height : 720 pixels
Frame rate : 29.970 fps
Writing library : x264 core 120 r2164 da19765
VLC did a poor job playing that file. I was getting about one or two second's worth of frames that played ok before it stuttered and pixelized for a second or two before playing again. The audio was AC3 stereo, and it played just fine.
However, when I play the same file using MediaPlayer Classic, the file plays really well. The system is based on a Soyo motherboard with Intel 845 chipset and it has Pentium 4 CPU running 2.53 Ghz (533 mhz FSB) with 512 kb L2 cache.
Ideas? Comments?
