MP4Box不連接視頻

我有MP4Box的問題，無法連接一個視頻中的視頻。我得到out.mp4文件（〜103 MB），但omplayer無法播放它。我有6個非常簡單的.mp4視頻，我希望它們合併成一個視頻。到現在爲止，我能做到這一點與命令，沒有任何問題：MP4Box不連接視頻

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

但現在omxplayer（也VLC）不能玩out.mp4視頻。這裏的MediaInfo輸出每6的一個視頻：

因此，所有的6個視頻有很好的MediaInfo輸出，但anways我嘗試執行命令測試沒有1個視頻（一個接一個），然後將它們合併，但相同結果。我得到奇怪的命令行輸出，當我執行命令mp4box：

正如你可以看到正好有「＃」部分視頻爲「無找到合適的目的地軌道......「線路，這很奇怪。到目前爲止，用於固定我的問題最接近的事情是這樣的命令：

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

卻是露出秒的視頻（爾納羅USLUGE video1.mp4）在連續兩次，然後剩下的就是正常的。我真的不知道該怎麼做。任何幫助將不勝感激。

感謝您的幫助，但我需要使用MP4Box來合併視頻而不是ffmpeg，因爲我的RPi3上只安裝了MP4Box。不管怎麼說，改變命令，可以確認該作品般的魅力（即使視頻丟失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.mp4

要知道，由於某種原因，輸出視頻不會與--loop環PARAM。 – Teemo

這是https://github.com/gpac/gpac/issues/549的副本，其中回答如下：FFmpeg有時會在SPS中添加PAR可選字段。因此MP4Box檢測到不同的SPS並且不能合併。

目前仍在討論GPAC是否應該能夠將此更改作爲解決方法進行檢測。請在根本問題上發表意見：https://github.com/gpac/gpac/issues/13。

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

好知道TNX – incBrain

您還可以使用ffmpeg來連接你的MP4文件，如描述here：

首先你要轉碼視頻，MPEG2-TS這樣的：

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 
...

然後用它們連接起來：

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

我測試了它與your videos（你發佈在github上的鏈接），它工作得很好。

也有可能做到這一點，而不形成使用命名管道中間.ts文件，這可能與此類似：

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

卻是露出秒的視頻（爾納羅USLUGE視頻1。 mp4）兩次在行

在我看來，你是從命令行兩次添加它。
