• How to embed m3u8 from ffmpeg Raspberry in Network Webserver

  25 octobre 2022, par FunnyO

  I have a Raspberry-Pi converting an RTSP-Stream to HLS-Segments via ffmpeg.
Now when I try to embed the Stream,

  


  I use this :

  


  &#xA;&#xA; &#xA;&#xA;<video class="video-js vjs-default-skin" width="400" height="300" controls="controls">&#xA;    <source type="application/x-mpegURL" src="http://192.168.2.45/files/hls/live.m3u8">&#xA;</source></video>&#xA;<code class="echappe-js">&lt;script src=&quot;https://vjs.zencdn.net/ie8/ie8-version/videojs-ie8.min.js&quot;&gt;&lt;/script&gt;&#xA;&lt;script src=&quot;https://cdnjs.cloudflare.com/ajax/libs/videojs-contrib-hls/5.14.1/videojs-contrib-hls.js&quot;&gt;&lt;/script&gt;&#xA;&lt;script src=&quot;https://vjs.zencdn.net/7.2.3/video.js&quot;&gt;&lt;/script&gt;&#xA;

  


  Working like a charm on the local raspberrypi apache2 Server.

  


  Now the problem is, I cannot display this stream with the identical code on a seperate device.

  


  What am I doing wrong ?
Is there a Firewallport I need to open ?
I dont think so ?
I can access the files when opening : http://192.168.2.45/files/hls/ on the seperate device.

  


• Why failes ffmpeg with "Failed to inject frame into filter network : Internal bug, should not have happened" ?

  17 octobre 2023, par StackOverRigge

  I want to convert a MP4 video file into an animated gif file using ffmpeg. I am trying to do this in two steps :

  


  

  1. Create a palette image

  


  2. Convert the MP4 with the help of the palette image to a GIF file

  


  


  I'm using ffmpeg 6.0 essentials_build.

  


  First, I create a palette image :

  


  ffmpeg -v warning -i video.mp4 -vf "fps=15,scale=1366:768:flags=lanczos,palettegen=stats_mode=diff" -y palette.png


  


  Then, I'm trying to convert the MP4 to GIF :

  


  ffmpeg -i video.mp4 -i palette.png -lavfi "fps=15,scale=1366:768:flags=lanczos,paletteuse=dither=bayer:bayer_scale=5:diff_mode=rectangle" -y video.gif


  


  This command ends in this error message :

  


  Error while filtering: Internal bug, should not have happeneditrate=4279.9kbits/s speed=0.742x
Failed to inject frame into filter network: Internal bug, should not have happened

• os.path.join () on firstargv and list [closed]

  5 novembre 2019, par user243

  I am iterating through a directory and sorting the filenames based on time. These sorted filenames are then stored as a list. The directory is specified as firstargv

  I need to take each filename from the list and join it with the directory specified as firstargv creating an entire path so that I can pass it as file to ffprobe later for further process.

  Below is the code I am using but I am not getting desired result,

  import subprocess, sys, os
  
  
  
  firstarg=sys.argv[1]
  
  a = str(firstarg)
  
  time = sorted(os.listdir( a ), key=lambda s: s[9:])
  
  filename = time
  
  for y in filename:
  
      new_path = os.path.join(firstarg, *y)
  
  for z in new_path:
  
      p1 = subprocess.Popen (['ffprobe', '-i', z, '-show_entries', 'format=duration', '-sexagesimal', '-v', 'error', '-of', 'csv=%s' % ("p=0")], stdout=subprocess.PIPE)
  
      out = p1.communicate() [0]

  Any ideas here please ?
