I want to overlay multiple videos over a single video at specified interval of time.
have tried with different solution but it will not work as i aspect
i am use below command to overlay video over video
String[] cmdWorking3 = new String[]{"-i",yourRealPath,"-i",gifVideoFile1,"-i",gifVideoFile2,"-i",gifVideoFile3,
"-filter_complex",
"[0][1]overlay=100:100:enable='between(t,0,2)'[v1];" +
"[v1][2]overlay=130:130:enable='between(t,0,2)'[v2];" +
"[v2][3]overlay=150:150:enable='between(t,5,6)'[v3];",
"-map","[v3]","-map" ,"0:a",
"-preset", "ultrafast", filePath};
by using above command first two video completely works fine but last one will not enable
Edit:
//Working perfect
String[] cmdWorking11 = new String[]
{"-i",
yourRealPath,
"-i",
gifVideoFile1,
"-i",
gifVideoFile2,
"-i",
gifVideoFile3,
"-i",
gifVideoFile4,
"-filter_complex",
"[1]setpts=PTS+3/TB[1d];" +
"[2]setpts=PTS+7/TB[2d];" +
"[3]setpts=PTS+10/TB[3d];" +
"[0][1]overlay=100:100:enable='between(t,0,2)'[v1];" +
"[v1][1d]overlay=130:130:enable='between(t,3,6)'[v2];" +
"[v2][2d]overlay=130:130:enable='between(t,7,9)'[v3];" +
"[v3][3d]overlay=150:150:enable='between(t,10,13)'[v4];" +
"[1]asetpts=PTS+3/TB[1ad];" +
"[2]asetpts=PTS+7/TB[2ad];" +
"[3]asetpts=PTS+10/TB[3ad];" +
"[0:a][1ad][2ad][3ad]amix=4[a]",
"-map", "[v4]", "-map", "[a]", "-ac", "5",
"-preset",
"ultrafast",
filePath};
Above command is perfectly works fine but audio from the overlapped video is gone,can you please help me to solve this issue.
main Video time Duration is about 00:15 second and all overlay videos are about 3 second.
it would be great to helping out to solve this issue,Thanks in advance.
You need to delay your 3rd overlay video to start at the time of overlay.
To keep audio as well, include in filter_complex
Replace
-map 0:a
with-map '[a]' -ac 2
