Stream FLAC independent of input?
Posted: 21 May 2012 04:07
Hello, I am using VLC to stream music on my home network, via http. My music library contains music in many formats (flac, mp3, aac, vorbis). In order to avoid quality losses in transcoding, I would like the stream output to either be the original file, or transcoded to lossless (flac).
I first tried to send the original audio, no transcoding, with OGG muxing. It works for MP3, Vorbis, and FLAC, but AAC (M4A) is not supported.
I then tried the following sout, to transcode the input as FLAC muxed in OGG. It seems to work for every input format... except flac, for which I get the output listed below.
Any ideas how I could achieve what I want to do?
