我正在使用 FFmpeg 在视频上叠加一系列图像，但在某些 MP4 视频上有时会失败（但有时可以完美运行）。我的命令给出了如下错误：
Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument
我的 ffmpeg 命令如下：
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

有人可以建议我正确的解决方案吗？

看起来 ffmpeg MOV 复用器不支持 mp4 中的 amr_nb，但请尝试
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
如果不，
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
