Hello,
I am streaming to Broadcastify using the icecast server (a basic analog
feed for ham radio) on Linux. I receive the message:
MP3 queue full, dropping chunk
and the stream drops.
Anything I can do to stop getting this message?
My config file looks like this (is there anything that looks wrong in it?):
[rtl_sdr]
sample_rate = 1024000

center_freq_mhz = 146.64
gain_mode = 0        ; 0 = automatic gain, 1 = manual gain
tuner_gain = 90      ; in tenths of dB (e.g., 90 = 9.0 dB), only used when
gain_mode = 1
ppm_correction = 0   ; frequency correction in PPM (0 = disabled)
fm_mode = narrow     ; wide or narrow

[audio]
audio_rate = 22050
mp3_bitrate = 16
mp3_quality = 2
audio_buffer_seconds = 2

[audio_filters]
lowcut_enabled = true    ; true or false
lowcut_freq = 500.0      ; in Hz, frequencies below this will be attenuated
lowcut_order = 4         ; filter order (higher = steeper cutoff, but more
CPU)

[squelch]
enabled = true    ; true or false
threshold = -10.0  ; in dB, signals below this will be muted
hold_time = 125    ; in milliseconds, how long to keep squelch open after
signal drops
