使用FFMPEG將音頻與視頻合並時，消除視頻的不必要旋轉

Question

實際上我想將使用錄音機音頻文件的音頻覆蓋到錄制的視頻文件中。為此，我正在使用此鏈接中的 FFMPEG庫項目

問題：當我以人像模式捕獲視頻，然后將視頻與錄制的音頻合並時，可以正常工作，但問題是視頻旋轉了90度，然后可以進行合並。我不想旋轉視頻，而只想合並。

如果我在橫向模式下捕獲視頻，則合並音頻工作正常。

下面當前使用FFMPEG命令將音頻與視頻文件合並

ffmpeg -y -i Video.mp4 -i Audio.mp4 -c:v copy -c:a copy -strict experimental -map 0:v:0 -map 1:a:0 OutputFile.mp4

而且我也嘗試過使用下面的命令，但它不起作用

ffmpeg -y -i Video.mp4 -i Audio.mp4 -c:v copy -c:a copy -strict experimental -map 0:v:0 -map 1:a:0  -vf -metadata:s:v:0 rotate=0 OutputFile.mp4

和

ffmpeg -y -i Video.mp4 -i Audio.mp4 -c:v copy -c:a copy -strict experimental -map 0:v:0 -map 1:a:0  -vf -metadata:s:v:0 translate=1 OutputFile.mp4

而且我也有嘗試的可能性，但它對我不起作用。

任何幫助都是可以接受的。

提前致謝

這不是確切的答案。使用前置和后置攝像頭捕獲視頻時，您可以找到角度並根據角度執行ffmpeg命令...使用此鏈接，您將獲得一些想法使用FFmpeg旋轉視頻
