    Hi, I need to translate CMOS sensor RAW data (Bayer) into BT.1120 or other standard parallel digital video format (CEA-861) with 1080p30 performance. My application does not require any CODEC. Can I use the DM365 to do the job? Thanks, Yossi

    Hi, I'm a new user of the 6467 DVEVM. I've been trying to modify the "encode" demo that is included with the DVSDK to allow encoding of 1080 video. Simply changing the maxHeight and maxWidth parameters in the VIDENC1_Params struct is apparently insufficient, as the Venc1_create()...

I've been reading this thread hoping to discover as much as I can about 1080p30 support for the two 6467(T) DVEVM boards. The specs for the DVEVM for the T part indicate that its DVSDK contains...

    Hi Anshuman, Thanks for your reply. But I have another question. Can DM368 support 2*1080P(<=15fps) + 1*CIF triple stream if we get video data via V4L2 interface? firstly , DM368 support 4 /dev/video? Sencond, Does DM368 codec can support this capacity? Thanks. Rick

    In the encode demo of DM368, only UV420PSEMI and 1080I is supported. I'm trying to encode 1080P video of which the colorspace is UYUV. however, it seems128MBytes (68MBytes for CMEM) is not enough for DM368 to do such a job. I guess it is because that UYUVY need 2 bytes for each pix, while UV420PSEMI...
