Hello Anders Good news, I could decode a frame which I extracted from the usbsnoobs I did :-). See attached picture frame3-03.jpg. It uses the quality 0. Your black frame you sent me gets now correctly decode, too (frameA-01.jpg) I found the Huffman table in the Windoz driver file (TP6810.sys) at offset 0x2a59c. The QTable which I found in a text file on my Windoz box can be found in this driver file, also. I attached some binary files which I used to build the 2 attached jpeg. For example use: cat FFD8-Q0-320x240.bin huffman1.bin FFDA.bin frame3-3.bin >frame3-03.jpg to make the picture frame3-03.jpg. This information should the cam get going in Linux ;-) Happy Hacking, Thomas PS: I sent this to the linux-media mail list, because somebody else is interested about this information, too.
