We are working on DVR RDK v03.50.00.06. We use a customized usecase original from usecases/multich_vdec_vdis.c, pls ref another post: http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/p/261372/919800.aspx
We found a strange thing about the "speed" of decode-only case. The speed are under our expectation. Furthermore, lower decode channels sometimes are slower than more ones!! There seems be one invisible limitation. Is there any way to break the invisible limitation and then to reach the "full speed"?
