Could not find codec parameters for stream 0 (Video: png, none(pc)): unspecified size
使用ffmpeg将多个图片合成视频当中，连续合两次是可以成功的（中间有间隔20多秒的时间），第三次合并会出现错误：FFmpegCmd: Could not find codec parameters for stream 0 (Video: png, none(pc)): unspecified size
Consider increasing the value for the 'analyzeduration' and 'probesize' options。有没有大神知道该怎么解决？
命令如下：ffmpeg -f image2 -r 25 -i /storage/emulated/0/Pictures/VR_Video/VR_Sequence/img%d.png -b:v 8000k -s 2000x1000 -vcodec mpeg4 /storage/emulated/0/Pictures/VR_Video/VR_Video360Cache_20210604110134.mp4
