- Around line 193-194: Update transcodeAudioStream and the related boolean
fallback paths to track whether any muxer.addAudioChunk call completed
successfully during the current operation, rather than relying on wroteAudio set
before the call. Skip renderAndMuxOfflineAudio after any committed audio and
propagate the error or use a fresh muxer; preserve fallback only when no audio
chunks were committed, including cancellation returning false.

Do not fall back after partial audio muxing.
transcodeAudioStream sets wroteAudio before muxer.addAudioChunk completes. A later mux, decode, or encode error can therefore throw after earlier chunks were committed. The catch then calls renderAndMuxOfflineAudio with the same muxer and sidecar. Offline encoding starts at timestamp zero, so it can append overlapping or duplicated audio.
The boolean fallback paths have the same unsafe condition. Cancellation can also return false after earlier chunks were committed, although the current offline renderer exits when cancellation is already set.
Track successful muxer.addAudioChunk completion for the current operation. Use that state to skip fallback after any committed audio. Propagate the error or restart with a fresh muxer instead.
