Hi, I am not a v4l2 expert. I think you better ask about this problem to the driver's maintainer. Which driver this board uses? The kernel module maintainers are listed in <kernel source>/MAINTAINERS file, you need to know which driver your board uses and look inside this file for the maintainer e- mail address. Another option is send e-mail to the video4linux official mailing list: linux-media@xxxxxxxxxxxxxxxx Em Wednesday 08 July 2009, 李伟 escreveu: > Hello Lamarque Vieira Souza: > I have read your answer about how to make qbuf . > I am doing a VPU ( video process unit )test on imx27(Freescale company). > The test include v4l2 part which will communicate with tv out board and tv > in board.
