How to extract the first frame from a video ?
10 août 2024, par AndrewI 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 usingexec
:

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 asmultipart/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

I run the funtion indianull and expected it to convert a video , in my desired format + add logo + add subtitles ! Takes the original Video from on folder , Subtitles from another folder , and converts the video , and saves it in another folder ..


the issue i see only is :

"\[af#0:1 @ 0x600001ad9cb0\] Error sending frames to consumers: No space left on device \[af#0:1 @ 0x600001ad9cb0\] Task finished with error code: -28 (No space left on device) \[af#0:1 @ 0x600001ad9cb0\] Terminating thread with return code -28 (No space left on device) \[out#0/mp4 @ 0x600001dd8540\] video:0KiB audio:0KiB subtitle:0KiB other streams:0KiB global headers:0KiB muxing overhead: unknown"


I do defenitly have over 400GB free on My SSD !
Is an an speciffic folder that is full ? and can not hold any files ?


Any idea how to solve this ? or any suggestion how to try to solve ?
