因为使用vstack和hstack转到了2016版本。
我在android中使用以下代码：
String[] cmds = new String[]{"-i",video1+".mp4","-i",video2+".mp4","-i",video3+".mp4","-filter","complex","[1:v][2:v]hstack[bottom];[0:v][bottom]vstack",output+".mp4"};
但是我收到以下错误：

答案1
做这件事有很多种方法。
堆栈和虚拟堆栈
此方法使用堆栈水平堆叠video1，video2然后虚拟栈垂直堆叠video0在它们上面。
ffmpeg -i video0 -i video1 -i video2 -filter_complex \
"[1:v][2:v]hstack[bottom];[0:v][bottom]vstack"
output
如果需要缩放以匹配尺寸
如果您需要先缩放任何输入，然后添加规模筛选：
ffmpeg -i video0 -i video1 -i video2 -filter_complex \
"[1:v]scale=320:-1[left]; \
[2:v]scale=320:-1[right]; \
[left][right]hstack[bottom]; \
[0:v][bottom]vstack"
output
合并音频
你没有提到音频，但如果你还想合并所有音频，请添加合并：
ffmpeg -i video0 -i video1 -i video2 -filter_complex \
"[1:v][2:v]hstack[bottom];[0:v][bottom]vstack[v]; \
[0:a][1:a][2:a]amerge=inputs=3[a]" \
-map "[v]" -map "[a]" -ac 2 \
output
如果您只想要来自一个输入的音频，那么请不要使用 amerge，只需映射您想要的音频，例如-map 1:a。
对于旧版本：pad + overlay
你的破旧ffmpeg太旧了，无法使用堆栈过滤器，所以使用软垫和覆盖。
ffmpeg -noautorotate -i video0 -noautorotate -i video1 -noautorotate -i video2 \
-filter_complex \
"[0:v]scale=1280:-1[top];[1:v]scale=640:-1[left];[2:v]scale=640:-1[right]; \
[top]pad=iw:ih+(ih/2)[bg];[bg][left]overlay=0:overlay_h*2[bg2]; \
[bg2][right]overlay=overlay_w:overlay_h*2[v]; \
[0:a][1:a][2:a]amerge=inputs=3[a]" \
-map "[v]" -map "[a]" -ac 2 output
