    Y.Chay
    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, Currently I am considering of using DM365 for my project that require video processing of 4 D1 channel into H.264 for my DVR application. However, from the reference design it can only support for up to maximum 2 channel of D1. In this case, my option would be using 2 DM365. However, I do not sure...

    Hank Magnuski
    The NFS server in this case was an older Fedora distribution running a 2.6.20-1 kernel. When the portmap was being blocked and running under the default conditions, a TCPDUMP trace did not show any NFS packets being emitted by the DM365. I would assume that if the defaults were being used I would see...

  • Forum Post: DMAI updated for h.264?

    Tom Hanson
    Has the DMAI API been updated for h.264? The reason I ask is becuase the "encoder" example in dvsdk_demos/dm365, which uses the DMAI API does not supply any h.264 specific parameters to the encoder. AND while there is a set of pre-defined parameters (Venc1_Params_DEFAULT) and dynamic parameters...

    I'm trying to modify the DVTB demo code to strip out the parts I'm not interested in. In dvevmStParam.d the function dvevm_st_initValues() initializes dvevmStMapArr[] and then copies it to MAP. MAP is accessed by dvevm_st_getParam() which is not called within DVTB. MAP is also accessed as part...

    The on board video DACs on the DM365 do not support an arbitrary analog output, they only support TV (SD and HD) standard timings which use embedded syncs. A Video Graphics Array (VGA) output implies support for various resolutions and timings as well as requiring external syncs which are not available...
