Video capture card driver

  • Print

We have developed a driver and application for support of Brooktree and Conexant video capture processors, from the Bt8x8 chipset through to the Conexant CX2388x chipset as used on PCI video capture and television cards. This included programming the processor using its own dedicated RISC instruction set, as well as implementing display of the video buffer on screen via DMA or PIO, either using RGB or YUV via the overlay (“picture-in-picture”) feature. This also involved interfacing with a Philips tuner chip via the I2C interface.

This was later released to the open source community.
