  • Created widget libraries, demos and documentation for using the libraries
Video

Unmanned Airborne Video Capture

 

Project Details

  • Target: TI OMAP3530 with Logic PD SOM

Requirements / Challenges

  • Customer had no Linux experience; this was customer’s first Linux project
  • The video decoder chip they were using was not the same as the chip on the Logic PD SOM
  • DVSDK only decodes elementary stream; they were getting a transport stream

Solution

  • Implemented significant driver modifications to the video encoder chip
  • Converted encode stream to H.264 to stream the video
  • Decoded the decode stream for display

HD Video Overlay System

 

Project Details

  • Target: Freescale i.MX 6

Requirements / Challenges

  • Capture various input format video streams and display them in different output formats

Solution

  • Extended driver to support various input format
  • Set correct modeline based on Video ID autoconfiguration via (SPI, I2C or GPIO)
  • Added support for H.264 to USB and SD card
  • Bring up secondary HDMI output
Camera

Heat Sensing Handheld Device

 

Project Details

  • Target: TI DM365

Requirements / Challenges

  • Control the incoming Video Stream using various buttons
  • Extend DVSDK

Solution

  • Developed a library that can be used by User Interface for performing various functions (take still picture, store images/video on local storage, etc.)
  • Tied buttons to GPIO and to the Library API
  • Extended DVSDK to capture still images
Application Porting
