I saw that your ffmpeg version is quite old, updating can solve any bug that can be messing out your usage I've tried adding " -content_type 'audio/mpeg' -ice_name 'CBC' -ice_description 'CBC' " to make the Icecast request more complete, I don't know if they are mandatory to Limelight but they get rid of "It seems you are streaming an unsupported format." warnings on the ffmpeg log _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
