FFmpeg merge falhou com status

Error message

FFmpeg merge falhou com status {}

What it means

FFmpeg wrapper failure in merge_audio_video: the '-map 0:v -map 1:a -c copy' merge of separate video and audio files exited non-zero, meaning the streams could not be muxed (e.g. incompatible codecs, missing stream, or unreadable input).

Solutions

1. Confirm both input files exist and are fully written before merging
2. Capture ffmpeg stderr to identify which stream failed
3. Fall back to re-encoding one stream if codec compatibility is the issue
