Default VDPAU encoding

Is there any plan to add encoding api in VDPAU (and GPU based encoding), VAAPI already has them with intel releasing a hardware for same ?

Default Re: VDPAU encoding

VDPAU stands for Video Decode and Presentation API, so I don't think there are any plans.

Any hardware encoders are bad anyway, you can configure x264 to be just as fast and it'll still give a better picture. CUDA, OpenCL and such are not the holy grail of encoding. The hardware is simply not suitable.

VAAPI (AFAIK, but my knowledge coulb be outdated) currently has just a stub for encoding and considering what I wrote above, I doubt it'll get any traction.

The only thing needed is hardware decoding into system RAM. VDPAU supports this, it just needs someone to implement it into ffmpeg and/or mencoder.

Not sure about x264, but yeah VAAPI (latest) have encoding support and Moorestown platform from Intel will have hardware encoding, thats the reason I askek if NVIDIA seems to have any such plans :-)

Patch - as usually - welcome, just do not implement it for mencoder only!
