将MP4输入流中的章节复制到ffmpeg中的输出流

Question

I'm using ffmpeg to copy two MP4 input streams into one output container and I'm having trouble maintaining the chapter indexes from both files into the output stream.

I have two files, specified by streams.txt which is in the correct format, that both contain an H.264 video stream, an AC-3 audio stream and an AAC audio stream, and am concatenating the two files using the following ffmpeg command:

ffmpeg -f concat -safe 0 -i streams.txt -map 0:0 -map 0:1 -map 0:2 -c:v copy -c:a:0 copy -c:a:1 copy output.mp4

This correctly produces the output file that I want, with both files combined into an output file with all three streams. I am however having trouble adding the chapters from both input files into the output one. I understand that I'm supposed to use the -map_metadata option, but I'm having trouble with the format of it that doesn't produce the following error message:

Invalid chapter index 0 while processing metadata maps.

事实证明ffmpeg当前不支持MP4容器的章节串联。
