Hallo all,
I know that my question is kind out of topic but since I use pygtk for this
small project and on this list there are people which are familiar with C I will
dare to ask.
I'm new to python and do like it. For learning purposes I decided to write a
simple GUI for mencoder using pygtk but I have a problem regarding the user
feedback. Can somebody tell me why these two programs have different output? I
mean - why python's pipe "eat up" the debugging information printed by
mencoder to stderr preventing me from presenting a nice progress bar to the user?
Many thanks and sorry for the off topic question - Velko

def main():
f = os.popen('mencoder -dvd 1 -chapter 1-1 -ovc copy -oac copy -o delme.avi
2>&1')
if f == None:
return
line = None
while line != '':
line = f.readline()
print line
f.close()
return
main()

#include <stdio.h>
int main(int argc, char *argv[])
{
FILE *f = NULL;
char buf[1024];
size_t request = sizeof(buf);
f = popen("mencoder -dvd 1 -chapter 1-1 -ovc copy -oac copy -o delme.avi 2>&1",
"r");
if(!f)
return 1;
while(fread(buf, request - 1, 1, f) == 1) {
buf[request - 1] = '\0';
fprintf(stderr, "%s\n", buf);
}
fprintf(stderr, "%s\n", buf);
pclose(f);
return 0;
}
