I'm trying to call up flac's encoder from a Python program. I believe I
should be doing it ok, but I get completely different results when doing
it by hand and from the python script. Here's the command line:
$/usr/bin/flac --endian=little --channels=2 --sign=signed --bps=16
--sample-rate=44100 --delete-input-file /var/data/myfile.raw
This works fine when done by hand, and flac encodes the file.
Inside the script, I do a fork() and then, on the child, I do:
tw_comppath = "/usr/bin/flac"
filepath = "/var/data/myfile.raw"
os.execl(tw_comppath, "--endian=little", "--channels=2",
"--sign=signed", "--bps=16", "--sample-rate=44100",
In this case, the FLAC binary complains about not getting the proper
options (endian, channels, etc), but it claims it is getting
What am I doing wrong? I cannot seem to pass the parameters right using
Thanks for your enlightening....
