gspca (ubuntu 8.10) and sonixj camera problems
Hi All,
My system configuration is as folows:
- clean Ubuntu8.10 (live CD) - kernel 2.6.27
- my USB sonixj camera connected - it is 0c45:612a Microdia PC Camera (SN9C110)
- dmesg shows no errors or suspicious messages
Problem: I cannot get any application to work with my camera. Even svv mentioned in http://moinejf.free.fr/gspca_README.txt does not work. Logs for svv and streamer are below. Attached is also a raw file generated with svv (just 2kB in size). The logs show JPEG conversion errors. Anyone has a similar problem? Any helpful ideas on what to do?
I appreciate your help.
Thanks,
JJ
svv returns the following errors (or similar - it often asks for a different number of bits, sometimes it complains about unknown huffman code during JPEG decompression):
ubuntu@ubuntu:~/Desktop$ ./svv raw pixfmt: JPEG 640x480 pixfmt: RGB3 640x480 mmap method libv4lconvert: Error decompressing JPEG: fill_nbits error: need 2 more bits libv4lconvert: Error decompressing JPEG: fill_nbits error: need 2 more bits libv4lconvert: Error decompressing JPEG: fill_nbits error: need 2 more bits libv4lconvert: Error decompressing JPEG: fill_nbits error: need 2 more bits libv4lconvert: Error decompressing JPEG: fill_nbits error: need 2 more bits ubuntu@ubuntu:~/Desktop$
streamer (another application that I tried) returns a similar conversion error:
ubuntu@ubuntu:~/Desktop$ LD_PRELOAD=/usr/local/lib/libv4l/v4l1compat.so streamer -o a.jpeg files / video: JPEG (JFIF) / audio: none libv4l2: error converting / decoding frame data: v4l-convert: error parsing JPEG header: Not a JPG file ?

Did you get the last gspca from my repository?

No, I did not as I thought that the distro already contains one of the most recent versions of the drivers.
I have just done this and YES, IT SOLVED THE PROBLEM. Now all apps work!
Thank you very much for your (quite obvious) suggestion. Best regards,
JJ
