Hi -
I know a number of mjpegtools users also use the 'smilutils'
to process DV data - this may be of interest.
There is a bug in the function which initializes the .wav file's
header, the RIFF header length is 36 too small. Some programs
ignore errors in the riff_length field or perhaps only give a
warning (mp2enc's warning message about .wav input header is a good
example). Other programs, such as Apple's AC3 encoder ("A.Pack")
declare the file corrupt and refuse to process it.
The patch below fixed the problem. You'll need to recompile and
install smilutils because the affected function is in one of the
shared objects and not the smil2wav program itself.
Cheers,
Steven Schultz
