encoder/decoder lib included in cuda 3.2?

Hi,

In the cuda 3.2 release note there’re encoder/decoder lib included in.
Is there any document/sample of it in the linux side?
Or should it be the same as the C API listed here http://developer.download.nvidia.com/compute/cuda/sdk/website/Video_Decode.html ?

Thank you.

Hi,

It’s only for Xp.

Hi,

Only for windows?

I see.

There should be a correction on the linux release note then.

Thank you.

The video decode API is supported on Linux. The library libnvcuvid.so ships in the driver package, not the SDK. The necessary include file cuviddec.h is supplied in the SDK. All of this is discussed in the Nvidia video decoder API pdf supplied with the 3.2 toolkit documentation.

I couldn’t find a Linux decoder sample, either. But, I found a dialog “DGAVCDecNV Development Dialog with Nvidia”: http://neuron2.net/dgdecnv/cuda/cuda.html

The sample ‘cuh264dec[1].zip’ in the dialog is a good starting point to understand how to use decoder library.

Based on the sample, I could make a decoding routine for Linux.

If you wanted cuda-accelerated h264 encoding on linux, you could use MainConcept’s library:
