i wish to find a solution to this issue i have been facing for a long while, trying to publish a reel on instagram. It keeps returning this error: Media upload has failed with error code 2207026 which means its not in the required format, i have tried with countless videos, uploaded them to my google drive and input the link to the video but still the same error, i came across this: Facebook Graph API – Getting error 2207026 when trying to upload video

And also implemented the last suggesstion in my code as shown below:

public String uploadFile(MultipartFile file) {
        String extension = StringUtils.getFilenameExtension(file.getOriginalFilename());
        var key = UUID.randomUUID() + "." + extension;
        String directory = this.fileStorageLocation;
        Path newPath = Paths.get(directory).toAbsolutePath().normalize();
        try {
            Files.createDirectories(newPath);
            Path inputFilePath = newPath.resolve(StringUtils.cleanPath(key));
            Path outputFilePath = newPath.resolve("output.mp4");
            Files.copy(file.getInputStream(), inputFilePath, StandardCopyOption.REPLACE_EXISTING);
            executeFFmpegCommand(inputFilePath.toString(), outputFilePath.toString());

        } catch (IOException ex) {
            Logger.getLogger(FileService.class.getName()).log(Level.SEVERE, null, ex);
        }
        return key;
    }

    private void executeFFmpegCommand(String inputFilePath, String outputFilePath) throws IOException {
        String ffmpegPath = "C:\ffmpeg\bin\ffmpeg.exe";
        String[] ffmpegCommand = {
                ffmpegPath,
                "-i", inputFilePath,
                "-c:v", "libx264",
                "-aspect", "16:9",
                "-crf", "18",
                "-vf", "scale=iw*min(1280/iw\,720/ih):ih*min(1280/iw\,720/ih),pad=1280:720:(1280-iw)/2:(720-ih)/2",
                "-fpsmax", "60",
                "-preset", "ultrafast",
                "-c:a", "aac",
                "-b:a", "128k",
                "-ac", "1",
                "-pix_fmt", "yuv420p",
                "-movflags", "+faststart",
                "-t", "59",
                "-y", outputFilePath
        };

        ProcessBuilder processBuilder = new ProcessBuilder(ffmpegCommand);
        processBuilder.inheritIO();
        Process process = processBuilder.start();
        try {
            process.waitFor();
            System.out.println("FFmpeg command executed successfully.");
        } catch (InterruptedException e) {
            throw new IOException("Error executing FFmpeg command: " + e.getMessage(), e);
        }
    }

And uploaded the video to my drive and put in the link again, but still the same error, i dont know could be the issue, could someone provide a suggestion or a link to a video that has been tested with, because i dont see what am doing wrong, thanks.
