Eu tive um problema ao usar o FFmpeg para processar arquivos TGA em um arquivo MP4. Esta é uma versão do que estou fazendo que demonstra o problema.
ffmpeg -loglevel debug -y -r 60 -codec targa -i pipe:0 -r 60 -vf "tblend=average,framestep=2,tblend=average,framestep=2,tblend=average,framestep=2,setpts=0.125" -vcodec h264 -preset slow -crf 18 "Z:\path\to\final.mp4" < "Z:\path\to\image.tga"
Dá este erro:

Alguma ideia do que estou fazendo errado? Obrigado!
Eu tenho um programa externo que gera arquivos TGA, e eu quero usar o Java para ler esses arquivos, enviá-los para o FFmpeg e, em seguida, excluir os arquivos.
Devido à falta de um analisador TARGA, somente os TGAs de tamanho de arquivo fixo (ou seja, nenhuma compactação RLE) podem ser canalizados para o ffmpeg.
ffmpeg -f image2pipe -framerate 60 -vcodec targa -frame_size 6220844 -i pipe:0 ... "final.mp4" < image.tga
O valor de frame_size deve ser o tamanho do arquivo, em bytes, dos seus arquivos TARGA.
