♫ FIP Radio on weak LTE

٩(◕‿◕) EN: Personal toolkit for uninterrupted HiFi audio on Ubuntu — stable FIP radio streaming over unstable LTE connections.

...work in progress — tested in the field, open for improvements

≡≡≡ヽ(゜∀゜)ノ Quick start

if no sudo and for other pre-install adjusments (゜.゜) look here>

curl -O https://raw.githubusercontent.com/alexostn/fip-hifi-over-lte/main/fip-stream.sh
chmod +x fip-stream.sh
./fip-stream.sh          # FIP main
./fip-stream.sh jazz     # FIP Jazz

Add aliases so you type fjazz from anywhere:

# add to ~/.bashrc or ~/.zshrc
alias fip='~/fip-stream.sh'
alias fjazz='~/fip-stream.sh jazz'
alias frock='~/fip-stream.sh rock'
alias fgroove='~/fip-stream.sh groove'
alias fworld='~/fip-stream.sh world'
alias felectro='~/fip-stream.sh electro'
alias fhip='~/fip-stream.sh hiphop'
alias fpop='~/fip-stream.sh pop'
alias fmetal='~/fip-stream.sh metal'
alias freggae='~/fip-stream.sh reggae'
alias fnouveau='~/fip-stream.sh nouveautes'
alias fsacre='~/fip-stream.sh sacre'
alias fcultes='~/fip-stream.sh cultes'

source ~/.bashrc

( ˘・з・) Why this exists

GUI players freeze on mobile networks. Browser tabs eat RAM, forget your station, and don't reconnect cleanly.

This is a single bash script that keeps mpv alive through LTE drops — DNS pre-warm on start, native reconnect flags inside mpv, while true as a fallback, all events logged to ~/fip-reconnects.log.

Tested on Ubuntu 22.04 + PipeWire, external DAC via Onkyo receiver. --audio-format=s16 — faster on mobile, fewer underruns. Switch to floatp only if you add DSP processing.

(◕‿◕) RF API Integration — Metadata Sync Ce projet prépare l’intégration de l’API Radio France pour synchroniser les métadonnées live (titre, artiste, station) avec le flux audio.

Objectifs :

• suivre le titre en cours via RF Open API
• détecter changements de piste et désynchronisations
• logger events pour analyse (Prometheus-ready)
• brique réutilisable pour MVP curation humaine (ft_transcendence)

Statut : Accès API RF validé. Synchronisation metadata en cours.

( ･∀･)ﾉ━━━► What's inside

fip-stream.sh       main script — run this
fip-aliases.sh      shell aliases (optional)

Key mpv flags explained in comments inside the script. The notable ones:

• --audio-buffer=6.0 — 6s cushion for LTE dips (was 2.0)
• --demuxer-readahead-secs=20 — reads 20s ahead to survive short outages
• --stream-lavf-o-append=reconnect_streamed=1 — Icecast has no range-request, this is the fix
• --log-file=~/fip-reconnects.log — events logged directly by mpv, no pipe noise
• DNS pre-warm via Quad9 9.9.9.9 at startup — reduces silence after LTE reconnect

(づ￣³￣)づ Open questions / experiments in progress

This is an ongoing log of what works and what doesn't on mobile. If you've tried similar setups — PipeWire quantum tuning, DNS pre-warming, buffer strategies — issues and comments are open. Particularly interested in:

• SmokePing or similar latency heatmaps against icecast.radiofrance.fr
• Better PipeWire quantum settings for streaming (currently default 1024)
• macOS / non-PipeWire setups
• Other Radio France streams or similar Icecast sources
• Collected reconnect logs welcome — open an issue with your fip-reconnects.log snippet and network type (LTE/WiFi/tethering)

If you use a different stack (mpd, VLC CLI, liquidsoap) and have reconnect tricks — feel free to open an issue or PR.
