FFmpeg 裁剪过大无效

Question

我的视频裁剪器对我测试的所有视频都可以正常工作，但是来自 s20 ultra 的视频在 FFmpeg 中给了我一些错误，我真的不知道视频是否过大或不是我的源代码https://github.com/rushidevmurari/RushiCropVideo/blob/213166834b0bc6ce83ab3f4ac494f261a57d7436/app/src/main/java/com/androworld/allinonevideoeditor/videocrop/VideoCropActivity.java

我得到了这些链接，但对我的工作没有任何好处Error when cropping video using FFMPEG

我的命令

由于旋转侧数据，ffmpeg 正在自动旋转视频，因此在被裁剪之前它变为 2160x3840，从而导致错误。您可以使用-noautorotate 输入选项告诉它不要自动旋转。

I/System.out: "-y" "-noautorotate" "-ss" "0" "-t" "31" "-i" "/storage/emulated/0/Download/20210227_175547.mp4" "-vf" "crop=w=3837:h=2160:x=1:y=-2070" "-r" "15" "-vcodec" "mpeg4" "-acodec" "copy" "-b:v" "2500k" "/storage/emulated/0/VEditor/VideoCroper/20210227_175547-0-13.mp4"

我删除了不执行任何操作的选项。
