: Provide real-time feedback during the "muxing" stage (the process of combining video and audio) to pinpoint if the crash is caused by specific audio sample rates or bitrate headers. : Provide real-time feedback during the "muxing" stage
: If an MP4 encoding fails due to codec mismatch, the system should offer to automatically wrap the output in a .mov container or re-encode the audio to a compatible format (like moving from .wav to .aac ).
A useful feature to "draft" for this specific problem would be a .
