Issues accessing audio file during merge - solved

[eldi0s]

Hi,

thanks for your script. I was trying to use it on a Debian 13 (Trixie) system with HomeAssistant Core and MotionEye.

After evaluation of all steps I discovered that everything was working except for merging the audio with the video file.
I did get the error below and the video file did not contain any audio.

[in#1 @ 0x561d16420c80] Error opening input: End of file Error opening input file /var/lib/motioneye/Camera3/2025-01-05/10-09-50.mp4.aac. Error opening input files: End of file mv: der Aufruf von stat für '/var/lib/motioneye/Camera3/2025-01-05/10-09-50.mp4.temp.mp4' ist nicht möglich: Datei oder Verzeichnis nicht gefunden

As audio was working and generating a .wav file when accessing it directly from console with ffmpeg I was thinking about adding a delay before accessing and processing the file may fix it. Et voila. the below "sleep 5" fixed it for me.

stop)
    # Kill the ffmpeg audio recording for the clip
    kill $(cat /tmp/motion-audio-ffmpeg-camera-${camera_id})
    rm -rf $(cat /tmp/motion-audio-ffmpeg-camera-${camera_id})
    # kill $(cat /tmp/motion-audio-ffmpeg-camera-${camera_name})
    # rm -rf $(cat /tmp/motion-audio-ffmpeg-camera-${camera_name})
sleep 5
    # Merge the video and audio to a single file, and replace the original video file
    ffmpeg -y -i ${file_path} -i ${file_path}.aac -c:v copy -c:a copy ${file_path}.temp.${extension};
    mv -f ${file_path}.temp.${extension} ${file_path};
