YUV to RGB conversion can be done by vdpau video mixer or OpenGL. The mixer supports advanced de-interlacing methods, OpenGL only BOB. The advantage of NOT using the mixer is that it consumes less resources.
Quote:When I select AUTO for deinterlace
When choosing AUTO for deinterlace mode (preferred setting), de-interlacing gets kicked in automatically for interlaced material, provided that the flags of the input stream are correct.
AUTO for method is currently the same as temporal.
Thanks, all clear.
Two more questions:
1 - Is it normal that CPU usage is about 10% (or maybe even 20%) higher (on this build?) when using the more advanced VDPAU settings? I see spikes up to about 35% CPU usage (Ivy Bridge Celeron, FF-H264_VDPAU-VDPAU active, so it isn't the CPU doing all the work)
2 - When I access simple OSD elements (like the simple channel list, programm info or the part where audio/video settings etc. can be accessed) the picture remains very 'fluid', but when I press the back button - where more OSD elements appear on screen together with the channel- the image gets a tiny bit jerky, or maybe blurry. Don't know how to describe it excactly. Is that because picture now has to be rendered at the default OSD framerate? (I'm testing all this on a simple 60Hz CRT monitor, while watching 1080i 25fps (vdpau temporal/spatial -> 50fps) satellite channels)
