Dear all,

In one of the applications I am writing I need to convert a recorded wav
to mp3.

After using

session.recordFile() and obtaining a foo.wav file, I am calling

session.execute("system",lmLameCmd);

to invoke lame for the conversion.

The system command looks like this:
lmLameCmd = "/usr/local/freeswitch/bin/lame -V2 foo.wav foo.mp3 -S";


Here it comes the mystery. I am use lame 3.98.2 the mp3 file never
appears, if I use version 3.97 (older version), it does!.

If I execute the conversion from the command line, i get the mp3 with both
3.97 and 3.98.2

In fact, i am considering doing the conversions as background job, but I
am very curious to hear if this behavior has a pseudo-scientific
explanation

Try running it at the CLI and see if you see any errors. Also please
do not hijack threads. The original thread "[Freeswitch-users] XML-
RPC on different ip than 0.0.0.0" which was hijacked by clicking
reply, changing the subject and clicking send. Please in the future
do not do that as it clutters up the threading and could get your
query lost in the noise.

Thanks,
Brian

Hi Brian,

[anthony.minessale at g...]

maybe it's writing some err to stderr that is being suppressed somehow

I ran strace from freeswitch and from the command line. lame segfaults
when run from system FS.

The only obvious different i see is in the execve() /* XX vars */ apart
from the final Segfault

From
execve("/usr/local/freeswitch/bin/lame",
["/usr/local/freeswitch/bin/lame", "/tmp/foo.wav", "/tmp/foo.mp3", "-S"],
[/* 16 vars */]) = 0

Running out of stack space? The stack space we run freeswitch in is
fairly small. Programs launched from the freeswitch process inherit
this.

I run into this problem before. Don't remember the exact error but
might be segfault of lame runing in freeswitch-lua.

If you use Linux you would like to try iwatch. It's a perl program
watching your file system and can execute the lame command as soon as
it got the CLOSE_WRITE(or other) filesystem event.

Hi Steven,

Sounds like a very good tip. Do you have any example available to share? I
will be happy to upload it to the wiki when i put it up and running.
