FFmpeg를 사용하여 TGA 파일을 MP4 파일로 처리할 때 문제가 발생했습니다. 이것은 문제를 보여주는 내가 하고 있는 일의 버전입니다.
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"
다음 오류가 발생합니다.

내가 뭘 잘못하고 있는지 아시나요? 감사해요!
실제 구현:
TGA 파일을 출력하는 외부 프로그램이 있는데 Java를 사용하여 해당 파일을 읽고 FFmpeg로 보낸 다음 파일을 삭제하고 싶습니다.
답변1
TARGA 파서가 없기 때문에 고정된 파일 크기 TGA(즉, RLE 압축 없음)만 ffmpeg로 파이프될 수 있습니다.
ffmpeg -f image2pipe -framerate 60 -vcodec targa -frame_size 6220844 -i pipe:0 ... "final.mp4" < image.tga
Frame_size 값은 TARGA 파일의 파일 크기(바이트)여야 합니다.
