RTL-SDR EAS Monitoring Help

.ogg use foobar2000 Ogg-Vorbis. If I don't use FLAC, I use ogg vorbis.

You might need the codec pack for foobar. I dont remember if it is built in.

.ogg use foobar2000 Ogg-Vorbis. If I don't use FLAC, I use ogg vorbis.

You might need the codec pack for foobar. I dont remember if it is built in.

So I ended up just converting it to a .wav and using ffmpeg.

cmd prompt:

dsame --source sourcetest2.bat --text > alerts.txt

sourcetest2.bat:

@echo off
IF EXIST .\multimon-ng SET PATH=%PATH%;.\multimon-ng
IF EXIST .\ffmpeg SET PATH=%PATH%;.\ffmpeg\bin
ffmpeg -i .\sample-alert\WXR-RWT.wav -f s16le -ac 1 -ar 22050 -acodec pcm_s16le - | multimon-ng -t raw -a EAS -

output:

and it hangs there until I ctrl+c. After that alerts.txt populates with the weather message. Not sure if it is going to be like that using the sdr dongle or if it't just because of ffmpeg or the sample file
