Línea de trabajo

Start with the related ExoPlayer issue #10520 and investigate Media3's audio passthrough path for TrueHD streams; the issue does not name specific files or tests. Reproduce in the demo app using a TrueHD Atmos sample with gaps on an Android TV device connected to a compatible receiver. Done means the receiver plays without glitches and the demo app keeps audio in sync.

Descripción

bug needs triage
Version

Media3 main branch

More version details

When playing MKV files through ExoPlayer library based players (e.g. Plex) with TrueHD Atmos tracks on an Android TV device (e.g. Nvidia Shield Pro) with HDMI AV receiver with passthrough enabled the audio will glitch if there is gap in the TrueHD stream.

This is related to https://github.com/google/ExoPlayer/issues/10520

I will be submitting an PR that works around the issue by using a custom AudioOutput that does it's own IEC 61937 TrueHD MAT packing based on Kodi's code.

Devices that reproduce the issue
  • Nvidia Shield Pro
Devices that do not reproduce the issue

No response

Reproducible in the demo app?

Yes

Reproduction steps
  1. Obtain an Android TV device that supports TrueHD Atmos Audio Passthrough (e.g. Nvidia Shield)
  2. Obtain an AV Receiver that supports TrueHD Atmos audio.
  3. Obtain a sample of TrueHD with Atmos that has gaps (will be provided in email).
  4. Play the attached stream in the demo app.
Expected result

AV Receiver plays sample without glitching.

Actual result
  • Receiver Glitches (mine changes from TrueHD Atmos, to blank, then TrueHD Atmos)
  • ExoPlayer Demo losses audio sync.
Media

Will be provided in email.
