Emby 4.8.3.0 - Audio Conversion purpose to iOP app ?

[Gecko 71]

Hi,

I was wondering lately why is emby converting audio in the following scenario as the native audio format is read properly by the targeted device (iPhone with Emby native app) ? Isn't it an aggressive way of playing media in this case where the original material should be direct streamed ? It seems that any TrueHD stream is automatically converted to AC3 (tested 5.1 and 7.1).

 

All transcoding options active in the user preferences, convert trued to ac3

15:36:15.589   Stream #0:0(eng): Video: hevc (Main 10), yuv420p10le(tv, bt2020nc/bt2020/smpte2084), 3840x2160 [SAR 1:1 DAR 16:9], Level 153, 23.98 fps, 23.98 tbr, 1k tbn
15:36:15.589   Stream #0:1(eng): Audio: truehd, 48000 Hz, 7.1, s32 (24 bit), Start-Time 0.032s (default)
15:36:15.589 Stream mapping:
15:36:15.589   Stream #0:0 -> #0:0 (copy)
15:36:15.589   Stream #0:1 -> #0:1 (truehd (native) -> ac3 (native))

 

Deactivating audio transcoding in the user preferences, direct playing fine

07:51:46.156   Stream #0:0: Video: hevc (Main 10), yuv420p10le(tv, bt2020nc/bt2020/smpte2084), 3840x2160 [SAR 1:1 DAR 16:9], q=2-31, Level 153, 23.98 fps, 23.98 tbr, 90k tbn
07:51:46.156   Stream #0:1(eng): Audio: truehd, 48000 Hz, 7.1, s32 (24 bit) (default)
07:51:46.156 Stream mapping:
07:51:46.156   Stream #0:0 -> #0:0 (copy)
07:51:46.156   Stream #0:1 -> #0:1 (copy)

 

Full logs attached.

Thanks,

Gecko

Hi. It’s not supported by the  device. It’s working by accident with the mpv player  that we’re embedding but we need to disable that due to licensing.
