ストリームマッピングを使用してVOBファイルをffmpegと連結する方法は？

5つのVOBファイルがあります。それらを大きなmpegtsファイルに連結し、ビデオストリームと最後の（3番目の）オーディオストリームのみを保持したいと思います。残念ながら、ストリームの順序はVOB：

    Input #0, mpeg, from 'VTS_01_1.VOB':

Input #4, mpeg, from 'VTS_01_5.VOB':
      Duration: 00:02:45.18, start: 5930.104633, bitrate: 5897 kb/s
        Stream #4:0[0x1e0]: Video: mpeg2video (Main), yuv420p(tv), 720x576 [SAR 64:45 DAR 16:9], max. 7500 kb/s, 25 fps, 25 tbr, 90k tbn, 50 tbc

        Stream #4:4[0x1bf]: Data: dvd_nav_packet

だから私はこのコマンドを試しました：

ffmpeg -y f concat -i list.txt -map 0:v -map 0:a:2 -map 1:v -map 1:a:2 -map 2:v -map 2:a:2 -map 3:v -map 3:a:2 -map 4:v -map 4:a:2 -c copy -f mpegts joined.mpeg

List.txtに含まれる場所

file VTS_01_1.VOB
file VTS_01_2.VOB
file VTS_01_3.VOB
file VTS_01_4.VOB
file VTS_01_5.VOB

残念ながら機能しません、完全な出力：

ffmpeg -y -f concat -i list.txt -map 0:v -map 0:a:2 -map 1:v -map 1:a:2 -map 2:v -map 2:a:2 -map 3:v -map 3:a:2 -map 4:v -map 4:a:2 -c copy -f mpegts joined.mpeg

ストリームマッピングを適用して連結を実現するにはどうすればよいですか？

シェルからcatコマンドを使用して、.vobファイルを1つに連結できます。

次に例を示します。

同じディレクトリ内からfile1.vob、file2.vob、およびfile3.vobをAllfiles.vobに連結するには、次のコマンドを使用できます。

cat file*.vob > Allfiles.vob
