您的偏移量不正确.试试:
Your offsets are incorrect. Try:
ffmpeg -i v0.mp4 -i v1.mp4 -i v2.mp4 -i v3.mp4 -i v4.mp4 -filter_complex \
"[0][1]xfade=transition=fade:duration=0.5:offset=3.5[V01]; \
[V01][2]xfade=transition=fade:duration=0.5:offset=12.1[V02]; \
[V02][3]xfade=transition=fade:duration=0.5:offset=15.1[V03]; \
[V03][4]xfade=transition=fade:duration=0.5:offset=22.59,format=yuv420p[video]; \
[0:a][1:a]acrossfade=d=0.5:c1=tri:c2=tri[A01]; \
[A01][2:a]acrossfade=d=0.5:c1=tri:c2=tri[A02]; \
[A02][3:a]acrossfade=d=0.5:c1=tri:c2=tri[A03]; \
[A03][4:a]acrossfade=d=0.5:c1=tri:c2=tri[audio]" \

如何获取xfade offset 值:
How to get xfade offset values:
| 输入 | 输入持续时间 | + | 上一个xfade offset |
- | xfade duration |
= |
|---|---|---|---|---|---|---|
v0.mp4 |
4.00 | + | 0 | - | 0.5 | 3.5 |
v1.mp4 |
9.19 | + | 3.5 | - | 0.5 | 12.1 |
v2.mp4 |
3.41 | + | 12.1 | - | 0.5 | 15.1 |
v3.mp4 |
7.99 | + | 15.1 | - | 0.5 | 22.59 |
| input | input duration | + | previous xfade offset
