| Hi Victor, Do you want to YUV422 output from DSS? over which interface? ie discrete or embedded sync interface? Regards, Brijesh | |
| Hi Brijesh, I want to Discrete interface. Regards, Victor | |
| hi Victor, DSS natively does not support YUV422 output over discrete sync interface. But i have a way. In that case, you need to treat input YUV422 interleaved data as if it is RGB565 data and configure DSS input video pipeline as receiving RGB565 data. You need to disable all pixels processing in this pipeline, disable blending in overlay manager, connect only this pipeline to the overlay manager.. At the output of overlay manager, convert RGB24 data to RGB565 by setting videoifSize field and then enable TDM mode to send out single pixel over two clock cycles. This is how you could get YUV422 over 8bit discrete sync interface. All the pixel processing that you required, you need to do using another pipeline, in memory to memory mode.. Rgds, Brijesh | |
