• "FFmpeg : Error not transitioning to the next song in Discord Bot's queue."

  1er avril 2024, par noober

  I have 3 modules, but I'm sure the error occurs within this module, and here is the entire code within that module :

  I have tried asking ChatGPT, Gemini, or Bing, and they always lead me into a loop of errors that cannot be resolved. This error only occurs when the song naturally finishes playing due to its duration. If the song is playing and I use the command !skip, the next song in the queue will play and function normally. I noticed that it seems like if a song ends naturally, the song queue is also cleared immediately. I hope someone can help me with this

  


• Trying to encode video file as hevc error in python

  29 juin 2022, par jatt

  I am getting a syntax error when trying to run this code with it saying the end quotes being the error. process = sp.Popen(shlex.split(f'usr/bin/ffmpeg -y -s {width}x{height} -pixel_format bgr24 -f rawvideo -r {fps} -i pipe: -vcodec libx265 -pix_fmt yuv420p -crf 24 {output_filename}') stdin=sp.PIPE)

  


  I don't know why because the end quote is supposed to be there and I am not sure how to fix it.
The original code is from here : How to output x265 compressed video with cv2.VideoWriter

  


  import cv2
import numpy as np
import subprocess as sp
import shlex

width, height, n_frames, fps = 1344, 756, 50, 25  # 50 frames, resolution 1344x756, and 25 fps

output_filename = 'output.mp4'

# Open ffmpeg application as sub-process
# FFmpeg input PIPE: RAW images in BGR color format
# FFmpeg output MP4 file encoded with HEVC codec.
# Arguments list:
# -y                   Overwrite output file without asking
# -s {width}x{height}  Input resolution width x height (1344x756)
# -pixel_format bgr24  Input frame color format is BGR with 8 bits per color component
# -f rawvideo          Input format: raw video
# -r {fps}             Frame rate: fps (25fps)
# -i pipe:             ffmpeg input is a PIPE
# -vcodec libx265      Video codec: H.265 (HEVC)
# -pix_fmt yuv420p     Output video color space YUV420 (saving space compared to YUV444)
# -crf 24              Constant quality encoding (lower value for higher quality and larger output file).
# {output_filename}    Output file name: output_filename (output.mp4)
process = sp.Popen(shlex.split(f'usr/bin/ffmpeg -y -s {width}x{height} -pixel_format bgr24 -f rawvideo -r {fps} -i pipe: -vcodec libx265 -pix_fmt yuv420p -crf 24 {output_filename}') stdin=sp.PIPE)

# Build synthetic video frames and write them to ffmpeg input stream.
for i in range(n_frames):
    # Build synthetic image for testing ("render" a video frame).
    img = np.full((height, width, 3), 60, np.uint8)
    cv2.putText(img, str(i+1), (width//2-100*len(str(i+1)), height//2+100), cv2.FONT_HERSHEY_DUPLEX, 10, (255, 30, 30), 20)  # Blue number

    # Write raw video frame to input stream of ffmpeg sub-process.
    process.stdin.write(img.tobytes())

# Close and flush stdin
process.stdin.close()

# Wait for sub-process to finish
process.wait()

# Terminate the sub-process
process.terminate()


  


• How to add "ffmpeg" to the Cloud Run environment or to Dockerfile ?

  16 janvier 2021, par awabs

  I am triying to a logo to video that is uploaded to cloud storage using ffmpeg library, I deployed this code as cloud function is runs only with small size videos, so I decided to move to cloud run, but here I have to build container myself so I used this command instead

  


  gcloud builds submit --pack image=europe-west1-docker.pkg.dev/video-sharing-a1mfa/video-sharing-repo/my-image,env=GOOGLE_FUNCTION_TARGET=addLogo


  


  and it builds the image and I just had to create a service in the Cloud Run and it is running, but unfortunately when I trigger this function I get this error

  


  Error: spawn ffmpeg ENOENT
at Process.ChildProcess._handle.onexit (internal/child_process.js:268:19)
at onErrorNT (internal/child_process.js:470:16)
at processTicksAndRejections (internal/process/task_queues.js:84:21)


  


  Which I am not sure of but I guess is that ffmpeg in not installed in contanier (where it comes preinstalled in the gcloud functions env). Any idea how to install it or what the docker file configuration might be ?

  


  here is my code :

  


  const { Storage } = require('@google-cloud/storage');
const projectId = 'video-sharing-a1mfa';
let gcs = new Storage({
    projectId
});

const os = require('os');
const path = require('path');
const spawn = require('child-process-promise').spawn;


exports.addLogo = async (req, res) => {

const event = JSON.parse(req.body);
const bucket = event.bucket;
const contentType = event.contentType;
const filePath = event.name;

console.log('File change detected, function execution started');
if (path.basename(filePath).startsWith('resized-')) {
    console.log('We already renamed that file!');
    return;
}
const destBucket = gcs.bucket(bucket);
const tmpFilePath = path.join(os.tmpdir(), path.basename(filePath));
const metadata = { contentType: contentType };
const tmpLogoPath = path.join(os.tmpdir(), 'watermark.png');
await destBucket.file('watermark.png').download({
    destination: tmpLogoPath
})

const newPath = path.join(os.tmpdir(), 'output.mp4')

await destBucket.file(filePath).download({
    destination: tmpFilePath
});
console.log('file downloaded to temp');

console.log('adding watermark');

var str = "overlay=10:10"

await spawn('ffmpeg', ['-i', tmpFilePath, '-i', tmpLogoPath, '-filter_complex', str, newPath]);


console.log('watermark added');

return destBucket.upload(newPath, {
    destination: path.dirname(filePath) + '/resized-' + path.basename(filePath),
    metadata: metadata
});;
};
