I have problem with MP4Box, can't concatenate videos in one video. I get out.mp4 file (~103 MB) but omxplayer can not play it. I have 6 very simple .mp4 videos and I want them to merge in one video. Until now, I was able to do that with command, without any problems:

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

but now omxplayer (also vlc) can not play out.mp4 video. Here is mediainfo output for every one of 6 videos:

So all 6 videos have good mediainfo output but anways I tried executing command to test without 1 video (one by one), and then merging them, but same result. I get strange command line output when I execute mp4box command:

As you can notice there are exactly "#" videos parts as "No suitable destination track found..." lines, which is strange. So far closest thing for fixing my problem is this command:

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 

but it is showing second video (Cornaro USLUGE video1.mp4) two times in row and then rest is normal. I am really out of idea what to do. Any help will be appreciated.

助けていただきありがとうございますが、RPi3にはMP4Boxしかインストールされていないため、ffmpegではなくMP4Boxを使用してビデオをマージする必要があります。とにかく、コマンドを変更し、これが魅力のように機能することを確認できます(ビデオにPARパラメータ情報がない場合でも):

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

ここでffmpeg説明されているように、mp4 ファイルを連結するために使用することもできます。

まず、次のようにビデオを MPEG2-TS にトランスコードする必要があります。

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
...

そして、それらを次のように連結します。

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

あなたのビデオ(github に投稿したリンク) でテストしたところ、問題なく動作しました。

名前付きパイプを使用して中間 .ts ファイルを作成せずにこれを行うこともできます。これは次のようになります。

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
