ffmpeg 版本 2.8.4 出现“zoompan”错误，在 2.6 中没有出现

升级到最新版本的 ffmpeg 2.8.4 后，我现在遇到了“zoompan”复杂过滤器的错误。这在早期版本 (2.6) 上运行良好。如果我删除该特定命令，进程就会运行。

导致错误的行：

zoompan=z="min(zoom+0.0015\,1.5)":d=700:x="if(gte(zoom\,1.5)\,x\,x+1/a)": y="if(gte(zoom\,1.5)\,y\,y+1)":s=1280x720'

整个命令

          cmd =   'ffmpeg'
          cmd +=  ' -loop 1 -i ' + base_images[0] + ' -loop 1 -i ' + base_images[1] +  ' -loop 1 -i ' + base_images[2] +  ' -loop 1 -i ' + base_images[3] 
          cmd +=  ' -filter_complex " '
          cmd +=  ' nullsrc=size=1280x760 [base]; '
          cmd +=  '[0:v] setpts=PTS-STARTPTS,scale=640x380 [upperleft];'
          cmd +=  '[1:v] setpts=PTS-STARTPTS,scale=640x380 [upperright];'
          cmd +=  '[2:v] setpts=PTS-STARTPTS,scale=640x380 [lowerleft];'
          cmd +=  '[3:v] setpts=PTS-STARTPTS,scale=640x380 [lowerright];'
          cmd +=  '[base][upperleft] overlay=shortest=1 [tmp1];'
          cmd +=  '[tmp1][upperright] overlay=shortest=1:x=640 [tmp2];'
          cmd +=  '[tmp2][lowerleft] overlay=shortest=1:y=380 [tmp3];'
          cmd +=  '[tmp3][lowerright] overlay=shortest=1:x=640:y=380"'
          cmd +=   ',zoompan=z="min(zoom+0.0015\,1.5)":d=700:x="if(gte(zoom\,1.5)\,x\,x+1/a)":y="if(gte(zoom\,1.5)\,y\,y+1)":s=1280x720'
          cmd +=  ',drawbox=enable="gt(t\,1)*lt(t\,7)":x="(iw/6)":y="(ih/2)-100":[email protected]:width=iw/1.5:height=100:t=max'
