Overlay di FFmpeg gagal karena codec audio - bagaimana cara memperbaikinya?

Saya menggunakan FFmpeg untuk overlay serangkaian gambar pada video tetapi pada beberapa kesempatan pada beberapa video MP4 gagal (tapi kadang-kadang berfungsi dengan baik). Perintah saya memberikan kesalahan seperti:

Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument

Perintah ffmpeg saya diberikan di bawah ini:

ffmpeg -y -i myvideo.mp4 -loop 1 -i img_%d.png -strict -2 -filter_complex [0:v][1:v]overlay=39:54:shortest=1:enable='between(t,0,4)' -codec:a copy Preview.mp4

Adakah yang bisa menyarankan saya solusi yang tepat?

Sepertinya ffmpeg MOV muxer tidak mendukung amr_nb di mp4, tetapi coba

ffmpeg -y -i myvideo.mp4 -loop 1 -i img_%d.png -strict -2 \
-filter_complex [0:v][1:v]overlay=39:54:shortest=1:enable='between(t,0,4)' \
-atag samr -copy_unknown -c:a copy Preview.mp4 

Jika tidak,

ffmpeg -y -i myvideo.mp4 -loop 1 -i img_%d.png -strict -2 \
-filter_complex [0:v][1:v]overlay=39:54:shortest=1:enable='between(t,0,4)' \
-c:a aac Preview.mp4
