• ffmpeg returns "method SETUP failed : 404 Not Found"

  1er juillet 2019, par Alex

  We’re using ffmpeg (build ffmpeg-20190628-098ab93-win32-static) to take a snapshot from camera RTSP streams on a Win 10 system. On some cameras, we’re getting this error :

  [rtsp @ 06813ac0] method SETUP failed: 404 Not Found
  
  rtsp://username:password@example.com: Server returned 404 Not Found

  Here’s an example command we use :

  ffmpeg -y -i rtsp://username:password@example.com -vframes 1 -pix_fmt yuvj420p 
  
    -vf select='eq(pict_type\,I)' -q:v 1 _test.jpg

  However, VLC can load the same stream (we can’t use VLC, though) from the same machine. Additionally, we’ve opened the firewall to ffmpeg (it popped up the two firewall dialogs and we allowed it through).

  We’ve found posts on the DESCRIBE error but nothing on SETUP. Any help is appreciated. Thank you.

  Update : In VLC, that RTSP stream asks for credentials twice for some reason. Wondering if that’s the cause.

• ffmpeg cmd not running through nodejs getting error like error initializing filter \'select\' with args \'"not(mod(n\'\n']"

  22 juillet 2019, par Nileshdeora1122

  hello everyone i need your help i’m working on ffmpeg as following by blog post https://contextneutral.com/snippet/how-to-run-ffmpeg-from-inside-of-nodejs
  now i’m doing the same my ffmpeg command running successfully on the terminal but not working with nodejs.
  basicaly i’m trying to run :

  "ffmpeg -loglevel panic -y -i "video.mp4" -frames 1 -q:v 1 -vf "select=not(mod(n\,40)),scale=-1:120,tile=100x1" video_preview.jpg "

  my nodejs code looklike this :

  let ffmpeg = spawn(
  
  'ffmpeg', [
  
  '-i', `${ Inputvideofile }`,
  
  '-y', 
  
  '-frames',1,
  
  '-q:v', '1', 
  
  '-vf', ' "select=not(mod(n\,120)),scale=-1:40,tile=10x1 "  ',
  
  `${ outpputImgstripe }`
  
  ]);
  
  ffmpeg.on('exit', (statusCode) => {
  
      console.log(statusCode)
  
    if (statusCode === 0) {
  
       console.log('conversion successful')
  
    }
  
  })
  
  ffmpeg
  
    .stderr
  
    .on('data', (err) => {
  
      console.log('err:', new String(err))
  
    })
  
  
  
  module.exports = router;

  The error im getting is :

  Error initializing filter \'select\' with args \'"not(mod(n\'\n']
  
  err: [String: 'Error reinitializing filters!\nFailed to inject frame into filter network: Invalid argument\nError while processing the decoded data for stream #0:0\n']
  
  err: [String: 'Conversion failed!\n']
  
  1

  i think the error is :

  '-vf', ' "select=not(mod(n\,120)),scale=-1:40,tile=10x1 "  ',

  but don’t know how to solve pls help me
