# Mobile Transcode Rules for Lyrion Music Server
# Optimized custom-convert.conf rules for mobile Squeezebox clients
#
# This plugin provides optimized transcode rules for mobile streaming apps.
# Each app can define its own rules based on its specific needs.
#
# Installation:
# 1. Copy the rules for your app to LMS prefs/custom-convert.conf
# 2. Restart LMS
# 3. Your mobile app will automatically use these rules

# LyrPlay (iOS) - Optimized for iOS devices

# Note: Uses FT flag for fast pipeline launch to prevent timeout errors on iOS
# Conservative settings: 44.1kHz, 16-bit, moderate bitrates

# FLAC to FLAC transcoding with fresh headers for seeking support
# ALWAYS transcodes to generate complete FLAC headers for BASS push stream compatibility

# Add Your App's Rules Here
# ============================================================================
# To add transcode rules for your mobile app:
#
# 1. Set your app's Model name in SlimProto HELO capabilities
#    Example: Model=YourApp
#
# 2. Copy the template below and customize:
#    - Replace "YourApp" with your model name
#    - Adjust flags (IFT/FT/IF/I/F) based on your app's needs
#    - Set quality parameters (sample rate, bit depth, bitrate)
#
# 3. Test thoroughly with your app
#
# 4. Share your rules with the community!
#
