Thanks - I'm not sure how common the issue will be but it seems to be limited to 2 x Disney discs so far (and both report having a high audio bitrate). The majority of the sound track is fine, but you then hit these points and sound is dropped (the amount of the drop seems to vary by the users setup from a brief drop to my setup where it is 10 sec). We are just guessing it is ffmpeg related given the players that are affected but don't really know. Is it worth opening a Ticket at https://trac.ffmpeg.org/ or would it just be wasting everyone time (and also if so is the sample too large)?

No affirmative answer from me ... but I believe no. LAV Filters will surely not upmix any stereo with arbitrary parameters, and I believe it has no ProLogic decoder either. Leave that to an attached A/V receiver in your shelf...

Kodi DSPlayer is generally stable and maintained, but the MediaPortal TV-Server plugin is very buggy, which prevents me from moving from MediaPortal for live TV playback.

Hi, I get occasional audio dropouts when bitrstreaming atmos/truedhd. All other formats work fine. If I switch to decoding, also fine. Does anyone have any idea what could be causing the dropouts? (MPC-BE with internal renderer, MadVR, Win10)

Atmos bitstreaming is not fully understood. If the bitrate exceeds a certain limit, it breaks apart, because its not known how to handle that. This was never a problem with ordinary TrueHD since the bitrate doesn't get high enough. Unfortunately the specifications for that are not available anywhere online (not even to buy), since its not part of the IEC standard that usually controls HDMI bitstreaming. So if anyone knows how Dolby MAT (Metadata-enhanced Audio Transport) works - the format used to wrap TrueHD and Atmos for HDMI transmission, please let me know.

Nev is it possible to add an extra box in the audio decoding properties, for Atmos/truehd tracks? So I could choose to bitstream truehd tracks but software decode atmos/truehd tracks.
EDIT: Also, does anyone know why software decoding is so much quieter than bitstreaming? Last edited by iSeries; 9th January 2018 at 19:28. |

LAV doesn't currently know if a stream contains Atmos extensions.

Using wasapi exclusive so always 100% when sending lpcm (but regardless all are set to 100% anyway). I noticed this a bunch of years ago when I had a Yamaha avr and it's the same with my Denon now. Sending lpcm to my receiver is notably quieter than bitstreaming.
