Re: Mplayer+vdpau not playing h264
Currently you can't take screenshots in MPlayer when using hardware decoding. The screenshot filter only works if the video has been decoded before the filter chain, which is not the case with hardware decoding.
I think support for screenshots with VDPAU would not be too hard to implement, and the one-frame delay after pressing 's' could be removed at the same time. However there are a lot of other features missing from MPlayer too so I'm not sure whether I'll actually try to implement this particular one.
