When trying to record, streamer stops with the following output:
$ streamer -o capture---30712.avi -f rgb24 -s 320x240 -r 24 -t 99:59:59 -F
mono16 -R 32000
avi / video: 24 bit TrueColor (LE: bgr) / audio: 16bit mono (LE)
oss: read: Resource temporarily unavailable
$
(full debug output below)
I could track this down to this section of libng/plugins/snd-oss.c
rc = read(fd,buffer+count,blocksize-count);
if (rc < 0) {
if (EINTR == errno)
continue;
perror("oss: read");
exit(1);
with strace indicating that read returns not EINTR, but EAGAIN.
In this case the code should not fail, but retry reading.
So I suggest the following patch, which made streamer usable for me:

Now for completeness, the full debug output:
