Thanks Guru, and everyone for all your help! I am afraid that I am unable to find the h264vdec_sn.tcf file, perhaps it is not part of the publicly released files? However, Guru has very clearly explained the size limitations so that answers my original question, many thanks. Our application needs to decode higher resolution videos (960x544) - but at reduced framerate. Presumably given the aforementioned limitations there is no way to make this work?
