Hi all, I jumped into the cold water and I am trying to convert the dxr3/em8300 driver to the v4l2 api. I got some parts already working, but I think that the hardest parts are still missing. As you might think... yes I have some questions :)
1) The dxr3 has a hardware fifo, which is used to play content. Can I reuse videbuf1 or videbuf2 to manage the fifo? Are these the frameworks designed to support output devices - write operation to the device? Here you can find the current fifo impl. https://github.com/austriancoder/v4l2-em8300/blob/master/modules/em8300_fifo.c 2) The adv7175 chip support to different input data types: Video Input Data Port Supports: CCIR-656 4:2:2 8-Bit Parallel Input Format 4:2:2 16-Bit Parallel Input Format See http://dxr3.sourceforge.net/download/hardware/ADV7175A_6A.pdf for more details about the chip. Now I thought that I should use the v4l2-mediabus api for that, but I am not sure what pixel codes (V4L2_MBUS_FMT...) should be used for CCIR-656 4:2:2 8-Bit and CCIR-656 4:2:2 16-Bit. thanks -- Christian Gmeiner, MSc -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
