# NovArc's one change to VideoLAN's libvlcjni build script: VLC modules whose source is GPL (not LGPL)
# are left out of libvlc.so, like the modules VideoLAN already leaves out (batch 4 review L1). The list
# comes from license-audit.py, which checks every VLC source file and header compiled into each module
# (from the build's own dependency files). VLC's own source is unchanged.
# Lua plugin, RealRTSP access, headphone and mono audio filters, the dummy interface, the file and syslog
# loggers, the RTSP VoD server, the RTP and cycle stream outputs, the Dolby Surround decoder, the hqdn3d
# and rotate filters, the deinterlace filter (its yadif mode is GPL), the MMX I420-to-RGB converter (x86;
# the SSE2 one does the same), and the zvbi teletext decoder (libzvbi's packet-830 and pdc are GPL-2;
# VLC's LGPL telx decoder still shows teletext subtitles).
