Logitech webcam issues with Ubuntu 10.04 LTS

Update:

Fixed (well, a workaround): Setting environment variable LD_PRELOAD prior to running video problem solves issues on my box.

$ LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so cheese


---Original Text follows---

cheese and other video programs have been working rather poorly on my AMD64 bit Ubuntu Studio install.

Errors like the following show up:


libv4lconvert: Error decompressing JPEG: unknown huffman code: 0000ffd9
libv4lconvert: Error decompressing JPEG: unknown huffman code: 0000ffff
libv4lconvert: Error decompressing JPEG: unknown huffman code: 0000ffec
libv4lconvert: Error decompressing JPEG: unknown huffman code: 0000ffff
libv4lconvert: Error decompressing JPEG: unknown huffman code: 0000ffd9
libv4lconvert: Error decompressing JPEG: unknown huffman code: 0000fffd


Rebuilding the latest drivers from linuxtv.org didn't help. I'm still looking for a solution.

Note: Same camera produces same error on a second computer running same version of Ubuntu.

gstreamer-properties is a great test tool for this kind of thing.


I'm going to log a bug on this one.
