Hey, I posted this independently, and someone suggested I should send it to this mailing list. I don't read the list, so I'm not sure if this is useful or on-topic or what. My apologies in advance if this is noise. omap24xxvout alloc DMA page failed when I use openMAX on ZOOM2 board, following is my test command and output: gst-launch videotestsrc ! goosink_pp Setting pipeline to PAUSED ...
