Question

我在ffmpeg

中使用此命令

   ffmpeg -i test.flv -i /var/www/phpvibe/logo.gif -filter_complex "scale=1200:-1,overlay=0:0" -s 1280x720 -vcodec libx264 -s 640x360 -movflags test.mp4 2>&1

但我得到了这个

 string(42) "At least one output file must be specified"

更新： -

php代码： -

 $output ='{ffmpeg-cmd} -i {input} -i /var/www/phpvibe/logo.gif -filter_complex "scale=1200:-1,overlay=0:0" -s 1280x720 -vcodec libx264 -s {ffmpeg-vsize} -threads 4 -movflags {output}.mp4 2>&1';

完成输出： -

Answer 1

您输入-movflags而未在输出文件前指定值。它认为test.mp4是标志值，因此是你的问题。

必须至少指定一个输出文件
