  curl: (60) SSL certificate problem: certificate has expired
More details here: https://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.
HTTPS-proxy has similar options --proxy-cacert and --proxy-insecure.

• Using aler9/rtsp-simple-server, able to stream HLS from file but not from ffmpeg's stdin

  11 avril 2023, par Powercoder

  UPD : hehe, it actially works, but in chrome, not mozilla

  


  I want to display programmatically generated stream on a webpage in real time. For this I have rtsp-simple-server with RTSP and HLS enabled. I managed to publish a stream from file with command ffmpeg -re -stream_loop -1 -i file.mp4 -vcodec libx264 -f rtsp -rtsp_transport tcp rtsp://localhost:8554/mystream and see it at http://localhost:8888/mystream.

  


  But when I'm trying to do the same with python from the ffmpeg's stdin, I'm getting infinitely loading video instead of stream and browser console says "Uncaught (in promise) DOMException : The fetching process for the media resource was aborted by the user agent at the user's request". Here is my code :

  


  import random
import shlex
import subprocess
import time

import numpy as np


def main():
    width = 1024
    height = 720
    framerate = 1
    frame_duration = 1 / framerate
    cmd = shlex.split(
        f'ffmpeg'
        f' -y'
        f' -f rawvideo'
        f' -vcodec rawvideo'
        f' -s {width}x{height}'
        f' -pix_fmt bgr24'
        f' -r {framerate}'
        f' -i -'
        f' -r {framerate}'
        f' -force_key_frames expr:eq(mod(n,3),0)'
        f' -vcodec libx264'
        f' -crf 18'
        f' -preset ultrafast'
        f' -tune zerolatency'
        f' -f rtsp'
        f' -rtsp_transport tcp'
        f' rtsp://localhost:8554/mystream'
    )
    ffmpeg_process = subprocess.Popen(cmd, stdin=subprocess.PIPE)
    try:
        while True:
            image = np.full(
                (height, width, 3),
                (
                    random.randint(0, 255),
                    random.randint(0, 255),
                    random.randint(0, 255),
                ),
                dtype=np.uint8,
            )
            ffmpeg_process.stdin.write(image.tobytes())
            time.sleep(frame_duration)
    finally:
        ffmpeg_process.stdin.close()
        ffmpeg_process.wait()


if __name__ == '__main__':
    main()



  


  In the server's logs seems like no bad messages instead of single 404 status (is it just about favicon, right ?)

  How do I get my stream from python visible on a webpage ?

  


• Rotating gyro data in gopro footage with ffpmeg

  2 juillet 2023, par FPV Shenanigans

  I believe orientation of gyro data in some of my gopro clips is wrong. Reelsteady runs stabilization ok but it results in even worse than initial video shaky effect. I have filmed with gopro in 90 degree with orientation locked .

  


  Is it possible to amend metadata if ffmpeg to fix this ?

  


  the below is an example clip

  tried this

  


  ffmpeg.exe -i "F :\2023 THE ONLY COPY\Chasing surfers\GX010223.MP4" -c copy -metadata:s:v rotate=90 "F :\2023 THE ONLY COPY\Chasing surfers\GX010223_test.mp4"

  


  but reelsteady can't read metadata from a new video
