  • ffmpeg : Cover image for video

    15 avril 2014, par Michael Herrmann

    I have a video file video.mp4 with sound (file information and download links below). I also have an image cover.png which contains a logo and a caption for the video. I want to create a new video which starts by showing cover.png, then blends in the first frame of video.mp4 within one second, then continues to play video.mp4.

    My failed attempt :

    I used ffmpeg to extract the first frame of video.mp4 into image file first_frame.png. I then created video fade.mp4 with a transition from cover.png to first_frame.png :

    ffmpeg -loop 1 -i cover.png -r 24 -loop 1 -i first_frame.png -r 24 -filter_complex "[1:v][0:v]blend=all_expr=&#39;A*(if(gte(T,1),1,T/1))+B*(1-(if(gte(T,1),1,T/1)))&#39;" -t 2 fade.mp4

    I then wanted to simply concatenate fade.mp4 and video.mp4 to produce the desired result. I created a file mylist.txt with the following contents :

    file &#39;fade.mp4&#39;
    file &#39;video.mp4&#39;

    Then I issued the following command to ffmpeg :

    ffmpeg -f concat -i mylist.txt -c copy out.mp4

    Unfortunately, this produced a lot of warnings of the following form :

    [concat @ 00000000003580e0] Invalid stream index 1:01:24.05 bitrate= 136.3kbits/s

    The resulting video out.mp4 does correctly start with fade.mp4, but unfortunately continues with completely random colour patterns when it comes to playing video.mp4.

    File information for video.mp4 :
