No momento, estou tentando concatenar 3 vídeos que não têm fluxo de áudio e adicionam um arquivo de áudio na mesma etapa.
Eu criei este comando que deve fazer o trabalho:
ffmpeg -y -r 30 -i data\intro.mp4 -vcodec ppm -f image2pipe -i data\render.ppm -i data\outro.mp4 -i "data\I could be the one.mp3" -c:v libx264 -crf 18 -preset slow -pix_fmt yuv420p -c:a copy -filter_complex "[0:0] [1:0] [2:0] concat=n=3:v=1:a=0 [v]" -map [v] -map 3:0 -shortest -metadata title="Development of BrainStoneMod" -metadata description="This is the development of the BrainStoneMod starting from 08th April, 2013" -metadata author="The_BrainStone" -metadata copyright="2013" -metadata year="2013" -metadata composer="" -metadata TBPM="" -metadata TDAT="" gource.mp4
É realmente um longo comando, mas satisfez minhas necessidades até que eu quisesse gravar o vídeo entre uma introdução e um outro.
Estou recebendo este log:

O que devo fazer?
A propósito: Este é o comando que eu usei antes e funcionou muito bem:
ffmpeg -y -r 30 -i "data\I could be the one.mp3" -vcodec ppm -f image2pipe -i data\render.ppm -c:v libx264 -crf 18 -preset slow -pix_fmt yuv420p -c:a copy -map 1:0 -map 0:0 -shortest -metadata title="Development of BrainStoneMod" -metadata description="This is the development of the BrainStoneMod starting from 08th April, 2013" -metadata author="The_BrainStone" -metadata copyright="2013" -metadata year="2013" -metadata composer="" -metadata TBPM="" -metadata TDAT="" gource.mp4
Alguma idéia?
