The test program *is* a standalone program. What I meant was, when you
compile a rockbox simulator, and try to play the test file from there, does
it work fine ?

If you just want to see how the library was ported, you could also follow
the svn history.

Okay, try this:
ffmpeg -i cook_sample64.rm -acodec copy -f image2 out%d.raw

this command will output the raw compressed frames that are passed to the
ffmpeg decoder, and you could display them in hex with this : (for example,
frame 1)
xxd out1.raw

Then, uncomment the line #define DUMP_RAW_FRAMES in main.c to dump the same
raw input buffers from the test program. then xxd dump1.raw to compare with
out1.raw from the previous step.
The corresponding frames of course should be identical. (dump#.raw should be
identical to out#.raw).

If they're not, could you send the 2 frames you checked in their raw format
?
