Can't Play HEVC. Obsolete video card?

Mons1990 · 2016-10-27 12:49:05

Hi guys. I'm trying to play an HEVC video but neither Totem nor mplayer can play it. :-( The audio is correctly played, but not the video.

My computer has never given any performance problem, but i have to say that my video card is old. I'm posting the hardware configuration.
CPU: Intel Core i5-3570 (quad core, no HT) @ 3.40GHz
GPU: NVidia GeForce 9600 GT with 256MB of RAM
RAM: 8GB DDR3

The video is Full HD as the screen resolution.

I'm posting the mplayer output

MPlayer SVN-r37857 (C) 2000-2016 MPlayer Team

Possible reasons, problems, workarounds:
- Most common: broken/buggy _audio_ driver
  - Try -ao sdl or use the OSS emulation of ALSA.
  - Experiment with different values for -autosync, 30 is a good start.
- Slow video output
  - Try a different -vo driver (-vo help for a list) or try -framedrop!
- Slow CPU
  - Don't try to play a big DVD/DivX on a slow CPU! Try some of the lavdopts,
    e.g. -vfm ffmpeg -lavdopts lowres=1:fast:skiploopfilter=all.
- Broken file
  - Try various combinations of -nobps -ni -forceidx -mc 0.
- Slow media (NFS/SMB mounts, DVD, VCD etc)
  - Try -cache 8192.
- Are you using -cache to play a non-interleaved AVI file?
  - Try -nocache.
Read DOCS/HTML/en/video.html for tuning/speedup tips.
If none of this helps you, read DOCS/HTML/en/bugreports.html.

I tried wuth "ao=alsa" but nothing changes.

Thank you in advance for the answers.

Is mplayer the only player you tried? Your video card can't do HEVC, but your CPU is powerful enough for software decoding. Try mpv. It's also possible that the file is broken, so try other HEVC videos.

I tried different videos but it seems the problem was ALL OF THESE! I downloaded a sample video from x265.com and it works. Sorry. You can close. Thanks to Gusar for the answer.
