JPEG кодек на ARM, есть ли исходники или открытые проекты Опции

[Vitaliy_ARM]

Хочу прицепить видеокамеру к LPC2468. Нашел кое что с цифровым выходом но без встроенного кодека JPEG.

Поискал исходники в интеренете, так сразу ничего не нашел. Мож кто знает где поискать?

В uc/GUI есть поддержка вывода jpeg на дисплей. Правда, сам я ее не пробовал использовать. Вот цитата из мануала

9.2.1 Supported JPEG compression methods
This software implements JPEG baseline, extended-sequential, and progressive compression
processes. Provision is made for supporting all variants of these processes,
although some uncommon parameter settings aren’t implemented yet. For legal reasons,
code for the arithmetic-coding variants of JPEG is not distributed. It appears
that the arithmetic coding option of the JPEG spec is covered by patents owned by
IBM, AT&T, and Mitsubishi. Hence arithmetic coding cannot legally be used without
obtaining one or more licenses. For this reason, support for arithmetic coding has not
been included to the free JPEG software. (Since arithmetic coding provides only a
marginal gain over the unpatented Huffman mode, it is unlikely that very many
implementations will support it.) So far as we are aware, there are no patent restrictions
on the remaining code.
The library does cot contain provision for supporting the hierarchical or lossless processes
defined in the standard.
