So linux-next fa169db2b277ebafa466d625ed2d16b2d2a4bc82 with 20090415/series applies without any rejects and compiles just fine for Migo-R. However, during runtime I experience the same problem as with 2.6.30-rc plus 0033->0035 + 0036 or v2: / # /mplayer -flip -vf mirror -quiet tv:// MPlayer dev-SVN-rUNKNOWN-4.2-SH4-LINUX_v0701 (C) 2000-2008 MPlayer Team Playing tv://. TV file format detected. Selected driver: v4l2 name: Video 4 Linux 2 input author: Martin Olschewski <olschewski@xxxxxxxxxxxxxxxx> comment: first try, more to come ;-) v4l2: unable to open '/dev/video0': No such device or address v4l2: ioctl set mute failed: Bad file descriptor v4l2: 0 frames successfully processed, 0 frames dropped. Exiting... (End of file) / # Removing 0036 unbreaks the code and mplayer/capture.c works as expected. I also tried out v2 of your soc-camera-platform patch but it still does not work. Can you please test on your Migo-R board? I'd be happy to assist you in setting up your environment. / magnus -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
