Re: [Gwc-general] Encoding to MP3 problem, byte swapping occurs

[Alister H. <ali...@gm...>]

OK,
(1) if you want a fixed build of a version which is producing static, 
you can just rebuild after deleting this from encode.c:

     optcnt++;

     options[optcnt] = "-x";    /* Swap bytes */

But I guess this option must have been added because someone actually 
needed it... I wonder if it is machine specific and can be tested for at 
compile time, or if it is audio file specific?

(2) in 0.21-19 if you rename the start_encode_old() function to 
start_encode(), and rename the start_encode() function to 
start_encode_new_disabled(), then "Encode Selection As..." will work.
But again, based on the changelog I guess the new function must be 
needed on some systems:

 > BUGFIX: Encoding to ogg or mp3 has always been broken, can only 
encode to once during GWC session.  Fixed by using named pipe

The "old" function works fine on my system - I can encode more than once 
during a GWC session.  For the "Simple encode..." feature to still work 
with it I also had to remove this line:

     options[optcnt] = pipe_name ;    /* named pipe */

These changes and also a fix for "Simple encode..."ing mono files are in 
my git version:
