Hi,
maybe someone is able to help me / us.
I'm using an himedia Q10.
XBMC works well on this device with some configurations. HD-video is playing well in very good quality with libstagefrigth and in between with mediacodec as well (SPMC 13.2)
But the seemingly most simple task - decode SD (DVD) - video is a problem for this device with xbmc.
Lets say: other players like MX, wondershare and himedia-player make much better image-quality for SD-video as the xbmc-DVD-player. But: they are all not so good integrated in xbmc AND the DVD-Navigation is really perfect only with XBMC-DVD-Player!
If the original image quality is high and progressive (cinema), you see not such a great difference between the different players. But when you try to watch older 4:3 videos or interlaced-video the you have often really bad quality. So it seems to be a question of sherpeness, deinterlacing and scaling.
I made some tests and my impression is, that the quality grows a little bit when I choose Softwaredecoding instead of hardware-acceleration - but it is not a good modification for alle the other videos and the improvement seems to be very small.
Do you have any ideas what we can do to improve SD-video quality in XBMC ?
Which paramters for video and acceleration are the best for you?
Which parameters are making sence for HQ-scaling ? 0 % 100 % or 50 % ? Where is the difference ?
What is with postprocessing and parameters in advancedsettings.xml like "ppffmpegpostprocessing" and so on.
