我想转轮输出480X272的MP4
但如果片源不是16:9,除了用"-crop"手动裁之外,请帮忙写一个能自动裁剪到480X272的参数。
我目前的参数是这样的:
Title=480X272
TitleE=480X272
Command0=""<%AppPath%>\cores\ffmpeg" -y -maxfr 30 -i "<%InputFile%>" -title "<%Title%>" -timestamp "<%TimeStamp%>" -bitexact -vcodec h264 -coder 1 -bufsize 128 -g 250 -s 480x272 -qscale 25 -acodec aac -ac 2 -ar 32000 -ab 64 -f mp4 "<%OutputFile%>.MP4""
谢谢!
