    Hello, I am working on DM816x-EVM(Netra) based custom board. Custom board setup is as following: We have DM816x Video ports connected to FPGA logic. At video RX side FPGA will recieve video from HD-SDI and converts it to 1080p30/1080p25/720p50 format and feed to VIN0 (x16) of DM816x. At video...

  • Forum Post: Three video streams at 1080p60?

    MRI
    How can you do three 1080p60 streams with two video input ports? If you split the ports to 8 bits, you can't do 1080p60 with an 8 bit bus at 165 MHz. Please explain?

  • Forum Post: DM816x: H.264 decoder bit rate

    sweta bhatt
    Hi, I wanted to know whether DM816x H.264 decoder is dependent of video bit rate parameter or not. I have a requirement as below 1) to decode 4 1080p/ 4 1080i encoded streams at 15 Mbps. Is there any constraint/limitation to support maximum bit rate for each HD channel? 2) to decode 16 SD resolutions...

    Tiebing, Please have a look at this: http://processors.wiki.ti.com/index.php/TI81XX_PSP_VIDEO_CAPTURE_Driver_User_Guide#Querying_DV_preset There is code there to query current input resolution detected by the decoder. You'll need to get the file descriptor of the input stream, /dev/video0...

    Hi Hardik, After get the dual capture working and test it with the saLoopBack application I started with gstreamer, mainly I wanted to run two different pipelines, each pipeline capturing from a different port. However, I found that gstreamer is having problems to work properly in this case, basically...

    David Soto
    Hi Brijesh, Yes, I would suppose that that value 0x00000414 means an overflow on the port (not sure what means each bit on this register), however, this overflow is being caused by the absence of the SoG signal, because using gstreamer with the SoG enabled I can use the pipeline without problems and...

    Hi Brijesh, Thanks for your comments. For the time being I am using a very simple pipeline which works when the SoG signal is enabled, also I am not using OMX to capture since I am using the V4L2 capture driver: gst-launch v4l2src device=/dev/video0 always-copy=false queue-size=8 !

    David Aviv
    Hello, Following a previous conversation on this matter, I have understood that the DM8168 has an hardware limitation for video in (line length of 1920 bytes). Since I'm using an imaging sensor of 10 bits, which is extremely important for DSP purposes, I need to transfer line of 1920 of 10 bits...
