EDYTOWAĆ

Ze względu na użycie vstack i hstack przeszły do ​​wersji 2016.

I używam następującego kodu w Androidzie:

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"};

Można to zrobić na kilka sposobów.

hstack i vstack

Metoda ta wykorzystuje hstack do poziomego stosu video1i video2, następnie vstack pionowo stos video0na nich.

ffmpeg -i video0 -i video1 -i video2 -filter_complex \
"[1:v][2:v]hstack[bottom];[0:v][bottom]vstack"
output

Jeśli chcesz skalować, aby dopasować rozmiary

Jeśli najpierw musisz przeskalować dowolne wejście, dodaj filtr skalowania :

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

Łączenie audio

Nie wspomniałeś o dźwięku, ale jeśli chcesz połączyć wszystkie dźwięki, dodaj amerge :

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

Jeśli chcesz audio tylko z jednego wejścia, nie używaj amerge i po prostu zamapuj żądany dźwięk, na przykład -map 1:a.

W przypadku przestarzałych wersji: pad + nakładka

Twoje zdeprawowane ffmpegjest zdecydowanie za stare, aby używać filtrów stosu, więc używaj padu i nakładki .

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]; \
