Actually, I may have spoken too soon
When I do
ffprobe out0000.sw
I get
[s16le @ 0000029de496df60] Estimating duration from bitrate, this may be
inaccurate
Input #0, s16le, from 'out0000.sw':
Duration: 00:00:01.81, bitrate: 705 kb/s
Stream #0:0: Audio: pcm_s16le, 44100 Hz, 1 channels, s16, 705 kb/s
So while the file-size is exactly 160kb, the sample rate seems to be higher.
But when I do the command Paul suggested as-is, I get this:
Input #0, wav, from 'out0000.wav':
Metadata:
encoder : Lavf56.40.101
Duration: 00:00:05.00, bitrate: 256 kb/s
Stream #0:0: Audio: pcm_s16le ([1][0][0][0] / 0x0001), 16000 Hz, 1
channels, s16, 256 kb/s
Here's the output from the .sw command and its output:
ffmpeg -i "[rtmp url]" -map 0:1 -af aresample=16000,asetnsamples=16000 -f
segment -segment_time 5 -segment_format sw out%04d.sw
