Hi Guys !
I just find how to play smoothly 5D mov file directly on windows, using the graphic card to decode the h264 video stream.
I use the K-lite Mega Codec pack (4.7.5) with Media Player Classic HomeCinema
you can find it on http://www.free-codecs.com/download/...Codec_Pack.htm
the method :
go to View/Option
in Player -> Format, find Quicktime file and change the mode from quicktime to directshow (just click on "quicktime" on the right)
in Internal Filter, make sure that H264/AVC (DXVA) is checked
in External Filters, add a filter named Snell & Wilcox MXF Mux
and set it on block (on the right)
normaly it will work with sound if not you can add a filter on ffdshow audio decoder and set it on prefer.
