  • Concatenate audio with image and video using ffmpeg

    9 mai 2018, par huynq9

    I have 1 image, 1 audio file and 1 video. I would like to merge all of them to make a video which will

    • show the image and play audio file for the first 10s
    • play the video file

    here is what I was trying to do so far.

    ffmpeg \
    
-loop 1 -framerate 24 -t 10 -i item1.jpg \
    
-i "https://audio-ssl.itunes.apple.com/apple-assets-us-std-000001/Music/66/58/f7/mzi.eoocfriy.aac.p.m4a" \
    
-i item4.mp4 \
    
-filter_complex \
    
"[0]scale=432:432,setdar=1[img1]; \
    
 [1]volume=1[aud1]; \
    
 [2]scale=432:432,setdar=1[vid1]; \ 
    
 [img1][aud1][vid1] concat=n=3:v=1:a=1" \
    
outputfile.mp4

    I got the error :

    [Parsed_setdar_4 @ 0x3063780] Media type mismatch between the
    ’Parsed_setdar_4’ filter output pad 0 (video) and the
    ’Parsed_concat_6’ filter input pad 1 (audio) [AVFilterGraph @
    0x30479a0] Cannot create the link setdar:0 -> concat:1 Error
    initializing complex filters. Invalid argument

    I tried to googled but still cannot figure out what I am doing wrong ?

    Updated :
    I ran the following command :

    ffmpeg \
    
-loop 1 -framerate 24 -t 10 -i item1.jpg \
    
-t 10 -i "https://audio-ssl.itunes.apple.com/apple-assets-us-std-000001/Music/66/58/f7/mzi.eoocfriy.aac.p.m4a" \
    
-i item4.mp4 \
    
-f lavfi -t 1 -i anullsrc \
    
-filter_complex \
    
"[0]scale=432:432,setsar=1[img1]; \

[img1][1][vid1][3] concat=n=2:v=1:a=1" \
    
outputfile.mp4

    and got the following error :

  • FFMPEG - it takes frames from .avi but doesn't work for mp4

    15 mai 2019, par Zector

    I run the following PHP code in a loop in order to extract the frame from 10th second from a list of video (avi & mp4) :

    $command = "$ffmpegpath -y -i $input  -vframes 1 -ss 00:00:$fromdurasec -y $output";

    It seems that it generates frames for avi files but not for mp4.

    When I run the command manually in command-line it works as expected (as in takes the frame and saves it in folder). Please find below the full log of ffmpeg process :

  • Video parameters for best web scrolling performance [duplicate]

    22 février 2018, par biven

    This question already has an answer here :

    There is web application which provides next workflow. User uploads video -> backend(by using ffmpeg) transform this video for smaller size(320x240) -> web browser plays transformed video. Key feature of this application should be excellent scrolling possibility of video by progress bar. I mean that video should be scrolled as smoothly as possible (without any jumps) when user moves progress bar position back and forward.

    I thought that small size of video helps to provide good scrolling possibility. But that’s incorrect. I have 2 different videos, one scrolling perfect(as I want), second has same resolotion(320x240), but it is scrolling with jumps and breaks.

    By ffprobe I compared both videos and I have next results :

    Video 1(good scrolling) :

    What is the key parameter of video which provide possibility for good scrolling in web browser ?
