 This is a feature request, but also a minor bug report.

 The feature request is to have ffplay support hardware acceleration.
 Already described in this GSOC 2013 suggestion.

 http://wiki.multimedia.cx/index.php?title=FFmpeg_Summer_of_Code_2013#Hardware_Acceleration_.28hwaccel.29_API_v2

 - Integrate hardware acceleration into ffplay
   - Create a video-output (VO) infrastructure to ffplay
   - Port the SDL renderer to the new VO infrastructure
   - Add support for VA-API: VA renderer through vaPutSurface(), add
 -hwaccel -- option to select "vaapi" renderer
   - Add support for VDPAU (optional): VDPAU renderer through
 VdpPresentationQueueDisplay()

 IMO it is reasonable to expect that ffplay already does so. Certainly
 ffplay reports that _vaapi or _vdpau is supported. However a search for
 such an option in the long list of command line options remains fruitless.
 Maybe this could be documented with a small warning in -h to spare users
 from trying to figure out why it doesn't work.
