This change is needed for the same reason as b776e64 (livekit#722): A change in the resampler API introduced in libwebrtc m137 caused the output frame's samples_per_channel_ property to remain uninitialized. As a result, the length of the output slice was always calculated as zero, resulting in NativeAudioStream yielding audio frames without any sample data.

I'm unclear why #722 made a change at a higher level of the stack in NativeAudioSink rather than fixing it here. Zed calls AudioResampler::remix_and_resample directly, so switching to this repository's main branch broke audio playback in Zed. |
