将m4s片段合并为一个文件，确保文件顺序正确。例如：

cat video-0.m4s >> all.m4s

cat video-1.m4s >> all.m4s

cat video-2.m4s >> all.m4s

cat video-3.m4s >> all.m4s

cat video-4.m4s >> all.m4s

cat video-5.m4s >> all.m4s

cat video-6.m4s >> all.m4s

cat video-7.m4s >> all.m4s

cat video-8.m4s >> all.m4s

cat video-9.m4s >> all.m4s

cat video-10.m4s >> all.m4s

然后立即进行所有转换。ffmpeg -i all.m4s -c copy video.mp4

这不是尝试流方法时遇到相同的问题(could not find corresponding trex)。

我在all.txt文件中包含了所有想要的文件，其中包含

file 'video-0.m4s'

file 'video-1.m4s'

file 'video-2.m4s'

file 'video-3.m4s'

file 'video-4.m4s'

file 'video-5.m4s'

file 'video-6.m4s'

file 'video-7.m4s'

file 'video-8.m4s'

file 'video-9.m4s'

file 'video-10.m4s'

并且我尝试了ffmpeg -f concat -safe 0 -i all.txt -c copy video.mp4，导致了同样的问题。[mov,mp4,m4a,3gp,3g2,mj2 @ 0x55fde2d0c520] Could not find codec parameters for stream 0 (Video: h264 (avc1 / 0x31637661), none, 1280x720): unspecified pixel format
