I have the free Mac trial/development/beta version so time to buy a full licence. You're welcome! I forgot to mention that I compared the sizes of various FLAC compression levels and on your test file there was about 6% size difference between the default level 5 and level 2. Unfortunately, there is no practical way (as far as I know) to check the current compression level of a FLAC file. |

The FLAC compression level issue would apply when using MinimStreamer to transcode FLAC DXD to WAV on any low-powered device. The buffering issue seems to be specific to the Melco renderer and I hope the slight extra delay at the start of streaming doesn't cause any problem with other renderers. I will think about whether it would be useful to make this a configurable setting. Could this delay have any negative impact on the support for gapless playback on some renderer/control point combinations ? Regards, |

Because of issues like this, I will add a new option to control the amount of delay. The default will be no delay. |

I have the free Mac trial/development/beta version so time to buy a full licence. With the new update to MinimStreamer (0.5.22), this track should play (with WAV transcoding) if the audio is converted to use compression level 2. The update adds a new option to prebuffer audio but it turns out this is not needed in order to play this file. While making this change, I made some changes to the buffering pipeline that MinimStreamer uses and it seems these changes have resolved the issue. The prebuffering option is available in case it turns out to be needed for other tracks or with other renderers. If the track has too high a compression level to be transcoded in real time, prebuffering will enable it to start but it will stop or break up after a few seconds. |
