C++ ffmpeg lib version 7.0 - noice in exported audio
2 septembre 2024, par Chris PI want to make a C++ lib named cppdub which will mimic the python module pydub.


One main function is to export the AudioSegment to a file with a specific format (example : mp3).


The code is :

I have no run time error but i see this message in console :

I can play the exported mp3 file but there is background noise.

How to optimize this code that gets video frame as image
14 août 2024, par TSRI am quite new to mp4 file. But here is my working attempt to extract image frame given video url and a timestamp.


In reality the input url is an 8K 10hours 200GB video, so I can't download it all, I can't load it to memory, and this is an API call so it has to be fast.


Is there anything else I can optimize ?


My doubts :


- 

-
This line
ffprobe -v error -select_streams v:0 -show_entries packet=pos,size,dts_time -read_intervals ${timestamp}%+5 -of csv=p=0 "${url}"I chose this clingy 5s, in which case would this fail ?

-
Same line, I don't know what's going on under the hood of this
ffprobecommand, but I tested it with the big 8K video and it seems to complete fast. So is it safe to assume that the entire 200GB was not downloaded ? An explanation of how thisffprobecommand work would be appreciated

-
Based on trial and error, I concluded that the intervals returned is parsable by
ffmpegonly if the first frame until the timestamp is included. If I include only that the single frame interval,ffmpegsays it is an invalid file. (Makes sense cuz I don't think I'll get an image from a 4byte data.) However, how can I be sure that I am selecting the least number of intervals.

-
Worse bottleneck : The function
extractFrametakes 6seconds on the big video. It seems to read the entire video segment fetched (by the preceding subrange step). I couldn't find a way to jump to the last frame without computing. Is this how MP4 work ? I read somewhere that MP4 computes the current frame based on the previous. If that is true, does it mean there is no way to compute a specific frame without reading everything since the last keyframe ?

-
Finally, this
ffmpegline is fishy (I got it from SO Extract final frame from a video using ffmpeg) it says that it ovewrites the output at everyframe . Does it mean it is writing to the disk every time ? I experience severe degradation in performance when I used.pnginstead of.jpg. This tells me that the image is computed every
frame. Can we compute only the final image at the very end ?













Here is the working code to optimize.

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
0xbebbb1b7error 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-dataand 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
