Yes. You've done right. You can use this branch. Did you try and compare with the samples here: http://linux-sunxi.org/CedarXVideoRenderingChart Please do that and see if you have the same problems or play the files correctly. If so, cedar is running right.
For me it seems, that hw acc is working basically. There might be a codec issue in general with your files ...
