Я столкнулся с проблемой при использовании FFmpeg для обработки файлов TGA в файл MP4. Это версия того, что я делаю, которая демонстрирует проблему.
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"
Выдает эту ошибку:

Есть идеи, что я делаю не так? Спасибо!
Фактическая реализация:
У меня есть внешняя программа, которая выводит файлы TGA, и я хочу использовать Java для чтения этих файлов, отправки их в FFmpeg, а затем удаления файлов.
