UDP Stream issue #538
Description
Good afternoon,
I encountered an issue using UDP device on direwolf
Scenario
Audio sender: Windows 10 host with ffmpeg
Receiver: Ubuntu Desktop 22.04 with direwolf last release build from github today
On Windows host (audio sender)
ffmpeg -f dshow -i audio="Line 1 (Virtual Audio Cable)" -c 1 -acodec pcm_s16le -b:a 44100 -f mpegts udp://192.168.56.1:12000
I tried playing a test.wav generated with gen_packet and tested with atest.
On Ubuntu
If I try to listen the stream with VLC I can hear it loud and clear, but with direwolf with this command
direwolf -n 1 -a 10 -r 44100 udp:12000
Output:
Dire Wolf version 1.7
Includes optional support for: hamlib cm108-ptt
Reading config file direwolf.conf
Audio input device for receive: udp:12000 (channel 0)
Audio out device for transmit: null (channel 0)
Channel 0: Demodulator + option can't be combined with multiple frequencies.
Channel 0: 300 baud, AFSK 1600 & 1800 Hz, A+, 44100 sample rate / 4.
Note: PTT not configured for channel 0. (Ignore this if using VOX.)
