需求为将多个无声视频合成为一个视频,并添加背景音和字幕讲解音
The text was updated successfully, but these errors were encountered:
设置 addOutputOptions '-ignore_unknown'尝试,或者在使用FFCreator之前,可以先给无声视频添加一个空白音轨。ffmpeg -i i.mp4 -f lavfi -i anullsrc=channel_layout=stereo:sample_rate=44100 -c:v copy -c:a aac -shortest o.mp4
ffmpeg -i i.mp4 -f lavfi -i anullsrc=channel_layout=stereo:sample_rate=44100 -c:v copy -c:a aac -shortest o.mp4
Sorry, something went wrong.
感谢
