  • How to extract the first frame from a video ?

    10 août 2024, par Andrew

    I am trying to extract the first frame from a video to save it as a preview.

    


    Here's an almost working solution using ffmpeg :

    


    func extractFirstFrame(videoBytes []byte) ([]byte, error) {
    input := bytes.NewReader(videoBytes)

    var output bytes.Buffer

    err := ffmpeg.Input("pipe:0").
        Filter("select", ffmpeg.Args{"gte(n,1)"}).
        Output(
            "pipe:1",
            ffmpeg.KwArgs{
                "vframes": 1,
                "format":  "image2",
                "vcodec":  "mjpeg",
            }).
        WithInput(input).
        WithOutput(&output).
        Run()

    if err != nil {
        return nil, fmt.Errorf("error extracting frame: %v", err)
    }

    return output.Bytes(), nil
}


    


    The problem with this is that it can only process horizontal videos. For some reason it will throw a 0xbebbb1b7 error for a vertical videos. I don't understand why is that, probably because this is my very first time with ffmpeg.

    


    Also, I am concerned if this solution is optimal. My assumption is that the whole video will be loaded into the memory first, which is kinda bad and I would like to avoid that

    


    I use https://github.com/u2takey/ffmpeg-go, but errors are the same even if I run it using exec :

    


        cmd := exec.Command(
        "ffmpeg",
        "-i", "pipe:0",
        "-vf", "select=eq(n\\,0)",
        "-q:v", "3",
        "-f", "image2",
        "pipe:1",
    )


    


    Interestingly enough, I noticed that running command in the terminal will work as expected with any type of video ffmpeg -i .\video_2024-08-10_00-03-00.mp4 -vf "select=eq(n\,0)"  -q:v 3 output_image.jpg, so the problem may be on how I send those videos to my server. I useFiber and send videos as multipart/form-data and then read it like this :

    


        form_data, err := c.FormFile("image")
    file, err := form_data.Open()
    bytes, err := io.ReadAll(file)
    ....
    preview, err := extractFirstFrame(bytes)



    


    I also managed to find logs for the failed attempt :

    I also realized that the problem was not related to the video orientation, but to to the video from a specific source uploaded specifically on my server 🤡 Such a weird coincidence that I decided to test my video upload with those files, but anyway. And those are.... Downloaded instagram reels lol. But again, ffmpeg works just fine when ran in terminal

    


  • first audio lost when using ffmpeg to overlay one mp4 on top of a big mp4

    11 septembre 2024, par James Hao

    I searched a lot (including chatgtp and google), and tried a lot of methods, not work.
below is my ffmpeg command line on windows 10 :

    


    ffmpeg -i video.mp4 -i b-.mp4 -filter_complex "[0:v]setpts=PTS-STARTPTS[b1];[1:v]scale=300:-1,setpts=PTS-STARTPTS+0.0/TB[top];[b1][top]overlay=x=50:y=50:enable='between(t\,0.0,5)'[outv];[1:a]adelay=0|0[a1]; [0:a][a1]amerge=inputs=2[outa]" -map "[outv]" -map "[outa]" -pix_fmt yuv420p -c:a aac -ac 2 -c:v libx264 -crf 18 final_video6.mp4


    


    two mp4 files, b-.mp4 should be on top of video.mp4 and play from 0th second and scale to 300 :-1, [0:a][a1]amerge is to merge two audio from the mp4 files, using "-ac 2" to replace pan statement according to enter link description here

    


    in result mp4 file, the audio from video.mp4 is lost ; sometimes with the same instruction, but replace b-.mp4 with another mp4 file, the audio may partially lost. any help will be very appreciated.
below is the console output from ffmpeg :

  • FFMPEG is not working in app service post deployment

    1er mars 2024, par Tushar Gupta

    I using the Xabe.FFmpeg package to generate clips from a video. The code is basically converting a video to multiple clips and it's working fine in my local but whenever I am uploading the code to app service the code is not working.

    


    Stack : .net
App Service OS : Windows

    


    Error :

    I tried deploying the app service using different OS but still facing the same issue, I also tried using different packages but the result is same.
