• Discord v13 audioPlayer playing state changed to idle for unknown reason

  14 septembre 2021, par zS1L3NT

  When I play a song, the audioPlayer's state goes from buffering to playing to idle for no reason, without throwing any errors too. The weird thing is that the code I made runs perfectly fine on my Windows 11 Laptop. The error only occurs when I run the exact same code on my Ubuntu VPS. Here is the dependency report when run on the Ubuntu VPS

  What should I do to fix this ?

  


• Broken pipe error when using FFmpeg stream camera video

  14 septembre 2021, par Xiuyi Yang

  I try to write frames captured from a my laptop camera and then stream these images with FFmpeg. This is my code :

  


  import subprocess
import cv2
rstp_url = "rtsp://localhost:31415/stream"

# In my mac webcamera is 0, also you can set a video file name instead, for example "/home/user/demo.mp4"
path = 0
cap = cv2.VideoCapture(path)

# gather video info to ffmpeg
fps = int(cap.get(cv2.CAP_PROP_FPS))
width = int(cap.get(cv2.CAP_PROP_FRAME_WIDTH))
height = int(cap.get(cv2.CAP_PROP_FRAME_HEIGHT))

# command and params for ffmpeg
command = ['ffmpeg',
           '-y',
           '-f', 'rawvideo',
           '-vcodec', 'rawvideo',
           '-pix_fmt', 'bgr24',
           '-s', "{}x{}".format(width, height),
           '-r', str(fps),
           '-i', '-',
           '-c:v', 'libx264',
           '-pix_fmt', 'yuv420p',
           '-preset', 'ultrafast',
           '-f', 'flv',
           rstp_url]

# using subprocess and pipe to fetch frame data
p = subprocess.Popen(command, stdin=subprocess.PIPE)


while cap.isOpened():
    ret, frame = cap.read()
    if not ret:
        print("frame read failed")
        break

    # YOUR CODE FOR PROCESSING FRAME HERE

    # write to pipe
    p.stdin.write(frame.tobytes())


  


  After run this code, the following error occurs :

  


  


  Input #0, rawvideo, from 'pipe :' :
Duration : N/A, start : 0.000000, bitrate : 221184 kb/s
Stream #0:0 : Video : rawvideo (BGR[24] / 0x18524742), bgr24, 640x480, 221184 kb/s, 30 > tbr, 30 tbn, 30 tbc

Traceback (most recent call last) :
File "rtsp.py", line 42, in 
p.stdin.write(frame.tobytes())
BrokenPipeError : [Errno 32] Broken pipe

  


  


  Please help me fix this bug.

  After reply by Rotem, I modidied code as below :

  


  import subprocess
import cv2
import pdb 

rstp_url = "rtsp://localhost:31415/stream"

# In my mac webcamera is 0, also you can set a video file name instead, for example "/home/user/demo.mp4"
path = 0
cap = cv2.VideoCapture(path)

# gather video info to ffmpeg
fps = int(cap.get(cv2.CAP_PROP_FPS))
width = int(cap.get(cv2.CAP_PROP_FRAME_WIDTH))
height = int(cap.get(cv2.CAP_PROP_FRAME_HEIGHT))

# command and params for ffmpeg
command = ['ffmpeg',
           '-re',
           '-f', 'rawvideo',  # Apply raw video as input - it's more efficient than encoding each frame to PNG
           '-s', f'{width}x{height}',
           '-pixel_format', 'bgr24',
           '-r', f'{fps}',
           '-i', '-',
           '-pix_fmt', 'yuv420p',
           '-c:v', 'libx264',
           '-bufsize', '64M',
           '-maxrate', '4M',
           '-rtsp_transport', 'udp',
           '-f', 'rtsp',
           #'-muxdelay', '0.1',
           rstp_url ]


# using subprocess and pipe to fetch frame data
p = subprocess.Popen(command, stdin=subprocess.PIPE)


while cap.isOpened():
    ret, frame = cap.read()
    if not ret:
        print("frame read failed")
        break

    pdb.set_trace()
    # YOUR CODE FOR PROCESSING FRAME HERE

    # write to pipe
    p.stdin.write(frame.tobytes())

    cv2.imshow('current_img', frame)  # Show image for testing

    # time.sleep(1/FPS)
    key = cv2.waitKey(int(round(1000/fps)))  # We need to call cv2.waitKey after cv2.imshow

    if key == 27:  # Press Esc for exit
        break

p.stdin.close()  # Close stdin pipe
p.wait()  # Wait for FFmpeg sub-process to finish
cv2.destroyAllWindows()  # Close OpenCV window


  


  The error ocurs as below :

  


  


  Connection to tcp ://localhost:31415 ?timeout=0 failed : Connection >refused

• Debian php ffmpeg error "Could not get frame filename number 2 from pattern"

  22 août 2021, par Sam

  My code below works fine in on my osx laptop

  


  $sec = 1;
$ffmpeg = \FFMpeg\FFMpeg::create([
   'ffmpeg.binaries'  => exec('which ffmpeg'),
   'ffprobe.binaries' => exec('which ffprobe')
]);

$video = $ffmpeg->open($file);
$frame = $video->frame(TimeCode::fromSeconds($sec));
if(!file_exists($newFilePath)) {
      $frame->save($newFilePath);
      $this->output->writeln('make: ' . $newFilePath);
}


  


  but on debian I get error Could not get frame filename number 2 from pattern

  


  here is the error description from ffmpeg website

  


  


  This usually occurs because the output name is incorrect or some option was omitted.
If outputting a single image you need to include -frames:v 1.
If outputting a series of images you need to use the proper naming pattern as described in the image muxer documentation. For example, output_%03d.png will make a series named output_001.png, output_002.png, output_003.png, etc.
If outputting a single image that is continuously overwritten with new images, add -update 1.

  


  


  My filename looks fine to me

  


  here is the detailed error :
