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.
String[] cmdWorking3 = new String[]{"-i",yourRealPath,"-i",gifVideoFile1,"-i",gifVideoFile2,"-i",gifVideoFile3,
"-filter_complex",
"[3]setpts=PTS+5/TB[3d];" +
"[0][1]overlay=100:100:enable='between(t,0,2)'[v1];" +
"[v1][2]overlay=130:130:enable='between(t,0,2)'[v2];" +
"[v2][3d]overlay=150:150:enable='between(t,5,6)'[v3]",
"-map","[v3]","-map" ,"0:a",
"-preset", "ultrafast", filePath};
To keep audio as well, include in filter_complex
[1]adelay=3000|3000[1ad];
[2]adelay=7000|7000[2ad];
[3]adelay=10000|10000[3ad];
[0:a][1ad][2ad][3ad]amix=5[a]
Replace -map 0:a
with -map '[a]' -ac 2
