Setting up MinimStreamer for SynoCommunity ffmpeg4

[simoncn]

A transcoded WAV stream (not local file) has a length of zero in the WAV header. Some renderers can't handle this.

To enable these renderers to play a transcoded WAV stream, MinimServer provides the option to specify a length for the WAV header in the transcoded stream. For example, settting stream.transcode to *:wav-2GB sets the header length to 2GB-1 and settting stream.transcode to *:wav-4GB sets the header length to 4GB-1. Setting a header length in this way imposes a limit on how long the stream will play for.

Another option is to transcode to L16. This doesn't have a header length field.
