Ok so it seems that you defiantly have a mt9v112 sensor on slave address 0x48. So not only does the 6270 seem to use at least 3 different sensors the mt9v112 sensor seems to use two different slave addresses as well.
What exactly do you mean by blinking? Are getting any valid picture at all? it looks from your mplayer output you are suffering from the fact that sometimes libv4l has issues decoding jpeg frames. You could just disable jpeg on our driver by using "insmod ./sn9c20x.ko jpeg=0" when loading the driver and see if the picture is any better. Also i'm attaching an updated version of the mt9v112 sensor probe patch that will make the probe function check both 0x5d and 0x48 slave addresses please make sure it still works for your sensor. you can apply it wih the following commands # git fetch # git reset --hard origin/HEAD # git am </path/to/patch file> On Thu, Mar 12, 2009 at 3:14 PM, emeliot <[email protected]> wrote: > > I do it like you sad and now sensor is finding but not everything is > ok > > dmesg: > > Linux video capture interface: v2.00 > sn9c20x: SN9C20X USB 2.0 Webcam - 0C45:6270 plugged-in. > sn9c20x: I2C slave 0x5d returned error during write to address 0xff > sn9c20x: I2C slave 0x5c returned error during write to address 0x01 > sn9c20x: Micron Sensor ID: 0x1229 > sn9c20x: Detected MT9V112 Sensor. > sn9c20x: Webcam device 0C45:6270 is now controlling video device /dev/ > video0 > sn9c20x: Using yuv420 output format > usbcore: registered new interface driver sn9c20x > sn9c20x: SN9C20x USB 2.0 Webcam Driver v2009.01 loaded > > when I run mplayer the screen start blinking > > bash-3.2# LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so mplayer tv:// \ >> -tv driver=v4l2:width=640:height=480:fps=25:device=/dev/video0 -vo x11 > MPlayer dev-SVN-rUNKNOWN-4.3.2 (C) 2000-2009 MPlayer Team > CPU: AMD Athlon(tm) Processor (Family: 6, Model: 10, Stepping: 0) > CPUflags: MMX: 1 MMX2: 1 3DNow: 1 3DNow2: 1 SSE: 1 SSE2: 0 > Compiled with runtime CPU detection. > 137 audio & 292 video codecs > > Playing tv://. > TV file format detected. > Selected driver: v4l2 > name: Video 4 Linux 2 input > author: Martin Olschewski <[email protected]> > comment: first try, more to come ;-) > Selected device: SN9C20x USB 2.0 Webcam Driver > Capabilites: video capture read/write streaming > supported norms: > inputs: 0 = Webcam;v4l2: ioctl get input failed: Invalid argument > > Current input: 1 > Current format: unknown (0x30323953) > tv.c: norm_from_string(pal): Bogus norm parameter, setting default. > v4l2: ioctl enum norm failed: Invalid argument > Error: Cannot set norm! > Selected input hasn't got a tuner! > v4l2: Cannot get fps > v4l2: ioctl set mute failed: Invalid argument > v4l2: ioctl query control failed: Invalid argument > v4l2: ioctl query control failed: Invalid argument > Xlib: extension "Generic Event Extension" missing on display ":0.0". > Xlib: extension "Generic Event Extension" missing on display ":0.0". > ========================================================================== > Opening video decoder: [raw] RAW Uncompressed Video > VDec: vo config request - 640 x 480 (preferred colorspace: Planar > YV12) > VDec: using Planar YV12 as output csp (no 0) > Movie-Aspect is undefined - no prescaling applied. > VO: [x11] 640x480 => 640x480 Planar YV12 > Xlib: extension "Generic Event Extension" missing on display ":0.0". > Xlib: extension "Generic Event Extension" missing on display ":0.0". > [swscaler @ 0x992be40]using unscaled yuv420p -> rgb565 special > converter > Selected video codec: [rawyv12] vfm: raw (RAW YV12) > ========================================================================== > Audio: no sound > Starting playback... > libv4lconvert: Error decompressing JPEG: fill_nbits error: need 1 more > bits > libv4lconvert: Error decompressing JPEG: fill_nbits error: need 1 more > bits > libv4lconvert: Error decompressing JPEG: fill_nbits error: need 1 more > bits > libv4lconvert: Error decompressing JPEG: unknown huffman code: > 0000ffd9 > libv4lconvert: Error decompressing JPEG: fill_nbits error: need 7 more > bits > libv4lconvert: Error decompressing JPEG: fill_nbits error: need 4 more > bits > libv4lconvert: Error decompressing JPEG: fill_nbits error: need 3 more > bits > libv4lconvert: Error decompressing JPEG: unknown huffman code: > 0000ffd9 > libv4lconvert: Error decompressing JPEG: unknown huffman code: > 0000ffd9 > libv4lconvert: Error decompressing JPEG: fill_nbits error: need 7 more > bits > libv4lconvert: Error decompressing JPEG: fill_nbits error: need 1 more > bits > libv4lconvert: Error decompressing JPEG: unknown huffman code: > 0000ffd9 > > > > > > --~--~---------~--~----~------------~-------~--~----~ Lets make microdia webcams plug'n play, (currently plug'n pray) To post to this group, send email to [email protected] Visit us online https://groups.google.com/group/microdia -~----------~----~----~----~------~----~------~--~---
