On colour targets the image viewer hands every file its own decoder rejects to jpegp, including damaged ones, but jpegp barely checks its input. Corrupt and truncated files crashed or hung it: - At the end of the file GETC() kept returning stale bytes, so marker searches and table reads never ended. Feed EOI markers (FF D9) instead, which ends every loop, and stop calling read() there. This state is reset in OPEN(): the overlay loader does not clear .bss. - A file ending before any scan decoded as a blank image. Report it as corrupt instead. - Out of range header values were used as array indexes: Huffman and conditioning table IDs, Huffman table sizes, sampling factors, scan component counts and spectral selection. Reject them, and frames of zero width or with no components. - Invalid Huffman codes walked past the code length table, run lengths wrote past coefficient 63, and huge coefficients indexed past the IDCT clamp table. Bound all three. - An odd DAC segment length never ended its loop. - The coefficient buffer size could overflow an int.

Build Your Own Rockbox
1. Clone 'rockbox' from git (or extract a downloaded archive).
$ git clone git://git.rockbox.org/rockbox
or
$ tar xJf rockbox.tar.xz
2. Create a build directory, preferably in the same directory as the firmware/
and apps/ directories. This is where all generated files will be written.
$ cd rockbox
$ mkdir build
$ cd build
3. Make sure you have mips/m68k/arm-elf-gcc and siblings in the PATH. Make sure
that you have 'perl' in your PATH too. Your gcc cross compiler needs to be
a particular version depending on what player you are compiling for. These
can be generated using the rockboxdev.sh script in the /tools/ folder of the
source.
$ which arm-elf-eabi-gcc
$ which perl
4. In your build directory, run the 'tools/configure' script and enter what
target you want to build for and if you want a debug version or not (and a
few more questions). It'll prompt you. The debug version is for making a
gdb version out of it. It is only useful if you run gdb towards your target
Archos.
$ ../tools/configure
5. *ploink*. Now you have got a Makefile generated for you.
6. Run 'make' and soon the necessary pieces from the firmware and the apps
directories have been compiled, linked and scrambled for you.
$ make
$ make zip
7. unzip the rockbox.zip on your music player, reboot it and
*smile*.
If you want to build for more than one target, just create several build
directories and create a setup for each target:
$ mkdir build-fuzeplus
$ cd build-fuzeplus
$ ../tools/configure
$ mkdir build-xduoox3
$ cd build-xduoox3
$ ../tools/configure
Questions anyone? Ask on the mailing list or on IRC. We'll be happy to help you!
