http://www.codeproject.com/KB/audio-video/nVLC.aspx

the problem ist that i don´t know how to activate the GPU-Acceleration in libVLC.
Can anybody help me in this topic?

Best Regards,

--ffmpeg-hw

Thx....that´s the solution

Hi all, does "--ffmpeg-hw" still work? I tried several options in the nVLC example projects ("--ffmpeg-hw", "--avcodec-hw=any", "--avcodec-hw=dxva2"), but seems none of them works.
Could somebody help?

"--avcodec-hw=any" should work

Thanks for your reply.

I was using VLC 2.2.0 to play a 3840*2160 mp4:
- Start vlc in command line: vlc --avcodec-hw=any, the video is choppy
- Start vlc in command line: vlc --avcodec-hw=dxva2, the video looks good
- In nVLC example, calling libvlc_new with/without "--avcodec-hw=xxx" makes no difference, both choppy.

Did I miss something?

Try 2.2.1

Here same problem...
Somebody has any news?
Me i tested with --ffmpeg-hw and say that is not supported.
I try with --avcodec-hw=dxva2 or --avcodec-hw=any and nothing.
I tested also forcing the direct 3d with --vout=direct3d11 and then --avcodec-hw=dxva2
i tested veriso 2.2.1 2.2.2 and 3.0...
in the 3.0 i try also --vout=direct3d11 and --avcodec-hw=d3d11va
if i give the same parameters on command line works fine the video ils fluid and the cpu occupation go down to 5%.
Any idea/suggestion?

You're not supposed to pass vout and avcodec-hw to LibVLC. It controls them internally based on higher-level video control functions.
