我的 MP4Box 有问题，无法在一个视频中连接视频。我得到了 out.mp4 文件（~103 MB），但 omxplayer 无法播放。我有 6 个非常简单的 .mp4 视频，我希望它们合并到一个视频中。到现在为止，我可以用命令做到这一点，没有任何问题：

MP4Box -cat Awards\ -\ Recognitions\ Screens\ Video.mp4 -cat Cornaro\ USLUGE\ video1.mp4 -cat Cornaro\ USLUGE\ video1.mp4 -cat DIOCLETIANS_BREAKFAST.mp4 -cat FLAVOURS_OF_DALMATIA.mp4 -cat Prognoza.mp4 -cat Restaurants\ -\ Bars\ 2016.mp4 -cat WineHappyHour3.mp4 -new out.mp4

但现在 omxplayer（也是 vlc）无法播放 out.mp4 视频。这是 6 个视频中每一个的 mediainfo 输出：

所以所有 6 个视频都有良好的 mediainfo 输出，但是我尝试执行命令以测试没有 1 个视频（一个接一个），然后合并它们，但结果相同。当我执行 mp4box 命令时，我得到奇怪的命令行输出：

如您所见，“#”视频部分恰好是“未找到合适的目标轨道...”行，这很奇怪。到目前为止，解决我的问题最接近的是这个命令：

MP4Box -force-cat -add Awards\ -\ Recognitions\ Screens\ Video.mp4 -cat Cornaro\ USLUGE\ video1.mp4 -cat Cornaro\ USLUGE\ video1.mp4 -cat DIOCLETIANS_BREAKFAST.mp4 -cat FLAVOURS_OF_DALMATIA.mp4 -cat Prognoza.mp4 -cat Restaurants\ -\ Bars\ 2016.mp4 -cat WineHappyHour3.mp4 out.mp4

但它连续两次显示第二个视频（Cornaro USLUGE video1.mp4）然后休息是正常的。我真的不知道该怎么做。任何帮助将不胜感激。

这是https://github.com/gpac/gpac/issues/549的副本，其中已回答：FFmpeg 有时会在 SPS 中添加 PAR 可选字段。因此 MP4Box 检测到不同的 SPS 并且无法合并。

GPAC 是否应该能够检测到此更改作为解决方法仍在讨论中。请在根本问题上发表您的意见：https ://github.com/gpac/gpac/issues/13 。

NB @IncBrain：bs-switching 是 DASH 的功能，而不是 MP4。

感谢您的帮助，但我需要使用 MP4Box 来合并视频而不是 ffmpeg，因为我的 RPi3 上只安装了 MP4Box。无论如何，更改命令并可以确认这就像魅力一样（即使视频缺少 PAR 参数信息）：

MP4Box -force-cat -cat Awards\ -\ Recognitions\ Screens\ Video.mp4 -cat Cornaro\ USLUGE\ video1.mp4 -cat Cornaro\ USLUGE\ video1.mp4 -cat DIOCLETIANS_BREAKFAST.mp4 -cat FLAVOURS_OF_DALMATIA.mp4 -cat Prognoza.mp4 -cat Restaurants\ -\ Bars\ 2016.mp4 -cat WineHappyHour3.mp4 output.mp4

您还可以使用ffmpeg连接您的 mp4 文件，如下所述：

首先，您必须像这样将视频转码为 MPEG2-TS：

ffmpeg -i vid1.mp4 -c:v copy -bsf:v h264_mp4toannexb -f mpegts inter1.ts
ffmpeg -i vid2.mp4 -c:v copy -bsf:v h264_mp4toannexb -f mpegts inter2.ts
ffmpeg -i vid3.mp4 -c:v copy -bsf:v h264_mp4toannexb -f mpegts inter3.ts
...

然后将它们与：

ffmpeg -i "concat:inter1.ts|inter2.ts|inter3.ts" -c copy out.mp4

我用您的视频（您在 github 上发布的链接）对其进行了测试，效果很好。

也有可能在不使用命名管道创建中间 .ts 文件的情况下执行此操作，这看起来类似于：

mkfifo temp1 temp2
ffmpeg -i input1.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts temp1 2> /dev/null & \
ffmpeg -i input2.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts temp2 2> /dev/null & \
ffmpeg -f mpegts -i "concat:temp1|temp2" -c copy output.mp4

但它连续两次显示第二个视频（Cornaro USLUGE video1.mp4）

在我看来，您从命令行添加了两次。
