  • ffmpeg - why I have three video streams in the output file when I have one video input (one video stream), one logo input

    17 juillet 2024, par Yazhou

    Hi I'm using ffmpeg to transcode some video files from prores or dv to h264/mov. Also I want to add a logo on it and make some other changes.
The command line I use is

    


    ffmpeg -i input.mov -i logo.png -c:a aac -c:v libx264 -pix_fmt yuv420p -crf 18 -map 0:a? -map 0:v -filter_complex "yadif,[1]scale=iw*1:-1[wm];[0:v:0][wm]overlay=main_w-overlay_w-5:5" -disposition:v:0 default output_h264.mov

    


    And what I got has three video streams. One for the logo,one for the video with logo, and one for original video.

    


    Though I put the default video stream as the one with both video and logo as you can see for -disposition:v:0 default, and it's also playing that stream. But when I tried to upload it on Vimeo or Youtube, it uses the wrong stream.

    


    


    How can I change the command line to let ffmpeg only output one stream ?
And how can I remove the extra streams for the existed outcomes ?

    


  • FFMPEG - Merge multiple video in to one video, the output video has no audio

    26 octobre 2018, par Tan Pham

    My input file has 5 video and 1 picture. I want to merge all video to one video, play video at the same time.
    The layout of the output video like this :
    enter image description here

    Im using ffmpeg to merge video. this is my ffmpeg command :

    ffmpeg 
    
-i C:\VID\test1.mp4 
    
-i C:\VID\test2.mp4 
    
-i C:\VID\test3.mp4 
    
-i C:\VID\test4.mp4 
    
-i C:\VID\test5.mp4 
    
-i C:\VID\background.jpg 
    
-filter_complex 
    
" nullsrc=size=1280x720 [base]; 
    
[0] setpts=PTS-STARTPTS, scale=560x360 [video0];
    
 [1] setpts=PTS-STARTPTS, scale=280x180 [video1]; 
    
[2] setpts=PTS-STARTPTS, scale=280x180 [video2];
    
 [3] setpts=PTS-STARTPTS, scale=280x180 [video3];
    
 [4] setpts=PTS-STARTPTS, scale=280x180 [video4]; 
    
[5:v] scale=700x700 [image]; 
    
[base][video0] overlay=shortest=1 [tmp1]; 
    
[tmp1][video1] overlay=shortest=1:y=360 [tmp2];
    
 [tmp2][video2] overlay=shortest=1:x=280:y=360 [tmp3]; 
    
[tmp3][video3] overlay=shortest=1:y=540 [tmp4]; 
    
[tmp4][video4] overlay=shortest=1:x=280:y=540 [tmp5];
    
 [tmp5][image] overlay=570:10:enable='between(t,0,30)'"
    
 -t 30 -c:v libx264 output.mkv

    The output video layout is working fine but no audio in the output video.
    I want all audio off each video will be keep on the output video. play audio at the same time together.
    I’m using tutorial on this link : Create a mosaic out of several input videos
    Thanks for reading
