如何将特殊的ts文件合并到mp4？

Question

我有一些ts文件，我想将它们合并到mp4，我使用了如下命令，一些ts可以毫无问题地合并。

ffmpeg -i 'concat:01.ts|02.ts|03.ts|' -c copy -bsf:a aac_adtstoasc 01.mp4

然后我发现对于一些ts文件，当我使用上面相同的命令时出现如下错误，我该怎么做才能合并这些ts文件？

Answer 1

我从某人那里得到了答案，如下所示，选项“-f mpegts”将跳过 png 标头：

ffmpeg -f mpegts -i 'concat:01.ts|02.ts|03.ts|' -c copy -bsf:a aac_adtstoasc 01.mp4
