Holas...
Paso 1:
Cambio el fichero "xawtv/console/Subdir.mk":
--
#console/streamer : LDLIBS += $(THREAD_LIBS) $(ICONV_LIBS) -ljpeg -lm
console/streamer : LDLIBS += -shared $(THREAD_LIBS) $(ICONV_LIBS) -ljpeg -lm -o libstreamer.so
--
Paso 2:
Modifico el codigo de "xawtv/streamer.c":
--
int
//main(int argc, char **argv) //kapachov 13-10-2006
main_streamer()
{
char *argv[] = { "streamer", "-d", "-s", "352x240", "-t", "0:20", "-r", "24", "-o", "fichero.yuv", NULL };
int argc = 10;
int c,queued=0,noaudio=0;
char *raw_length=NULL;
char *val;
/* parse options */
ng_init();
read_config();
/* cfg_parse_cmdline(&argc,argv,cmd_opts_devices);
for (;;) {
if (-1 == (c = getopt(argc, argv, "haqdp:w:"
"o:f:r:s:t:b:j:" "O:F:R:")))
break;
switch (c) {
// general options //
case 'q':
quiet = 1;
break;
case 'a':
noaudio = 1;
break;
case 'd':
debug++;
ng_debug++;
break;
case 'w':
wait_seconds = atoi(optarg);
break;
case 'p':
parallel = atoi(optarg);
break;
// video options //
case 'o':
moviename = optarg;
break;
case 'f':
vfmt_name = optarg;
break;
case 'r':
fps = (int)(atof(optarg) * 1000 + 0.5);
break;
case 's':
if (2 != sscanf(optarg,"%dx%d",&video.width,&video.height))
video.width = video.height = 0;
break;
case 't':
raw_length = optarg;
break;
case 'b':
bufcount = atoi(optarg);
break;
case 'j':
ng_jpeg_quality = atoi(optarg);
break;
// audio options //
case 'O':
audioname = optarg;
break;
case 'F':
afmt_name = optarg;
break;
case 'R':
audio.rate = atoi(optarg);
break;
// errors / help //
case 'h':
usage(stdout);
exit(0);
default:
usage(stderr);
exit(1);
}

Paso 3:
Compilo la libreria "libstreamer.so";
Y ejecuto mi programa que llama a la funcion main_streamer.

Hmm... algo no cuadra...
Paso 4:
Cambio el fichero "xawtv/console/Subdir.mk":
--
console/streamer : LDLIBS += $(THREAD_LIBS) $(ICONV_LIBS) -ljpeg -lm
#console/streamer : LDLIBS += -shared $(THREAD_LIBS) $(ICONV_LIBS) -ljpeg -lm -o libstreamer.so
--
Paso 5:
Compilo el ejecutable "streamer";
ejecuto el programa "streamer"
