  • Merge 2 video files with thier audio in a single file side by side

    27 mai 2015, par meghana

    I need to merge 2 video files along with their audio in single file side by side.

    I am able to merge 2 video files in single file but it using audio of first video file only, where as I need to merge audio of second file as well.

    below is command I am using to do that.

    ffmpeg.exe -i input1.webm -vf "[in] scale=iw/2:ih/2, pad=2*iw:ih [left]; movie=input2.webm, scale=iw/2:ih/2 [right]; [left][right] overlay=main_w/2:0 [out]" -b:v 768k ouput.webm

    I have tried various way with amerge but no success. As I am new to FFMpeg, I am not sure how can I achieve this.

    EDIT

    Below is FFMpeg Command I have used for merging both files as suggested by @occvtech , still it is not merging audio of second audio

    ffmpeg.exe -i 3.mp4 -i 4.mp4 -filter_complex "[0:v] scale=iw/2:ih/2,pad=2*iw:ih[left];[1:v]scale=iw/2:ih/2[right];[left][right‌​]overlay=main_w/2:0 [out]" -map [out] -map 0:a -map 1:a -b:v 768k o5.mp4

    Below is console output for command
