  • Have some problem when merging two video files with ffmpeg and xfade filter [closed]

    12 septembre 2023, par song jin

    ffmpeg -i img_1.mp4 -i img_2.mp4 -i img_3.mp4 -i img_4.mp4 -i img_5.mp4 -filter_complex "[0:v]xfade=transition=wiperight:duration=1:offset=4[v0];[1:v]xfade=transition=wiperight:duration=1:offset=8[v1];[2:v]xfade=transition=wiperight:duration=1:offset=1[v2];[3:v]xfade=transition=wiperight:duration=1:offset=1[v3];[v0][v1][v2][v3]concat=n=4:v=1:a=0,format=yuv420p[v]" -map "[v]" -y -s 1920*1080 concat.mp4
I was using this command to merging multiple videos, and then the following problem occurred：

    


    Stream mapping:Stream #0:0 (h264) -> xfade
Stream #1:0 (h264) -> xfade
Stream #1:0 (h264) -> xfade
Stream #2:0 (h264) -> xfade
Stream #2:0 (h264) -> xfade
Stream #3:0 (h264) -> xfade
Stream #3:0 (h264) -> xfade
Stream #4:0 (h264) -> xfade
format:default -> Stream #0:0 (libx264)


    


    As a result, there will be multiple input streams in the video.
How can I solve it ?
I hope have only one input per video stream
I want to have only one input per video stream

    


  • concatenate non-stream subtitles problem ? [closed]

    6 mai 2022, par Norman Rogers

    Concatenated a series of videos into one using ffmpeg, but they each have detached (non-stream) subtitles.
To concatenate these I tried Subtitle Edit's join subtitle tool but since the subrip files don't keep a record of its host video's end time, it results in incrementing delay.
Don't want to burn the subtitles or necessarily embed it into a stream.
think it should be like

    


      

    1. retrieve end time of each vid

      2. 


    2. append tiny placeholder sub at end of each subtitle that ends at vid's end time

      3. 


    3. use subtitle edit's join tool

      4.
