MP4Box不连接视频
MP4Box不连接视频
提问于 2016-06-10 16:08:26
我对MP4Box有问题，不能在一个视频中连接视频。我得到out.mp4文件(~103 MB)，但omxplayer不能播放它。我有6个非常简单的.mp4视频，我希望他们合并在一个视频。直到现在，我才能在命令下做到这一点，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但是现在，omxplayer (也是vlc)不能播放out.mp4视频。以下是6个视频中每一个视频的mediainfo输出：

谢谢帮助，但我需要使用MP4Box合并视频，而不是ffmpeg，因为我只有MP4Box安装在我的RPi3上。无论如何，更改命令并确认这一点就像魅力一样(即使视频缺少PAR param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.mp4Stack Overflow用户

这是https://github.com/gpac/gpac/issues/549的一个副本，答案是: FFmpeg有时在SPS中添加PAR可选字段。因此，MP4Box检测到不同的SPS，并且不能合并。
目前仍在讨论GPAC是否应该能够检测到这一变化作为一种解决办法。请就根本问题：https://github.com/gpac/gpac/issues/13发表意见。
NB @IncBrain: B-开关是破折号的一个特点，而不是MP4。

您还可以使用ffmpeg连接您的mp4文件，如描述的这里
首先，您必须将视频转换为MPEG2 2-TS，如下所示：
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
...然后将它们连在一起：
ffmpeg -i "concat:inter1.ts|inter2.ts|inter3.ts" -c copy out.mp4我用你的视频 (你在github上发布的链接)对它进行了测试，它运行得很好。
在不使用命名管道创建中间.ts文件的情况下，也有可能做到这一点，这与以下类似：
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页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
