  • Capture CMOS video with FPGA, encode and send over Ethernet

    23 décembre 2015, par ya_urock

    I am planning a open source university project for my students based on Zynq Xilinx FPGA that will capture CMOS video, encode it into transport stream and send it over Ethernet to remote PC. Basically I want to design yet another IP camera. I have strong FPGA experience, but lack knowledge regarding encoding and transfering video data. Here is my plan :

    1. Connect CMOS camera to FPGA, recieve video frames and save them to external DDR memory, verify using HDMI output to monitor. I have no problems with that.

    2. I understand that I have to compress my video stream for example to H.264 format and put into transport stream. Here I have little knowledge and require some hints.

    3. After I form transport stream I can send it over network using UDP packets. I have working hardware solution that reads data from FIFO and sends it to remote PC as UDP papckets.

    4. And finally I plan to receive and play video using ffmpeg library.

      ffplay udp://localhost:5678

    My question is basically regarding 2 step. How do I convert pixel frames to transport stream ? My options are :

    1. Use commercial IP, like

    Here I doubt that they are free to use and we don’t have much funds.

    1. Use open cores like

      • http://sourceforge.net/projects/hardh264/ - here core generates only h264 output, but how to encapsulate it into transport stream ?
      • I have searched opencores.org but with no success on this topic
      • Maybe somebody knows some good open source relevant FPGA projects ?

    2. Develop harware encoder by myself using Vivado HLS (C Language). But here is the problem that I don’t know the algorithm. Maybe I could gig ffmpeg or Cisco openh264 library and find there a function that converts raw pixel frames to H.264 format and then puts it into transport stream ? Any help would be appriciated here also.

    Also I am worried about format compatibility of stream I might generate inside FPGA and the one expected at host by ffplay utility. Any help, hints, links and books are appriciated !

  • QT Video widget benchmarks

    7 juin 2018, par hagor

    I develop video wall for security cameras application/ multiple video stream application.
    To Decode video i use FFMPEG and make a QPixmap from decoded frame.
    What is the best way to show videos ? Is Qt opengl widget much faster then qtLabel ?
    Thanks !

  • Use ffmpeg in Unity [closed]

    26 avril 2020, par DenVebber

    I need to use FFmpeg library for develop Unity Android application. Are there any specific solutions for this ?
I know how to connect FFmpeg libraries to Java in Android Studio, but is it the best to use in Unity ?
