• Cannot Play RTSP Streams From the Internet

  17 avril 2023, par jnnks

  I am trying to receive an rtsp :// stream from the internet. There are many example streams running, but I cannot receive any of them.
ffplay and VLC both fail to receive data. I tried both UDP and TCP with various urls with no success.
Streaming from a local rtsp server with aler9/rtsp-simple-server Docker container works fine.

  


  This is the command I use to watch the stream :

  


  ffplay rtsp://rtsp.stream/pattern


  


  VLC fails with :

  


  [00007f58640015f0] satip stream error: Failed to connect to RTSP server rtsp.stream:554
[00007f58640015f0] access_realrtsp stream error: cannot connect to rtsp.stream:554


  


  What else can I try ?

  


• HTML5 video in Internet Explorer

  26 juin 2012, par Jamie Taylor

  I have 3 copies of a video :

  Raw AVI

  Encoded .mp4 (h.264 video and mp3 audio)

  Encoded .ogv, encoded with oggtheora

  My HTML 5 player runs in Firefox 14, Chrome 19 and Opera 12, it fails however in, you guessed it.. Internet Explorer 9. As far as I know the h.264 file should be picked up and play, however it's not.

  <video class="vid" width="550" height="400" controls="controls">
  
      <source src="test/charlie.mp4" type="video/mpeg"></source> 
  
      <source src="test/charlie.ogv" type="video/ogg"></source> 
  
      Nope.
  
  </video>

  Any ideas ?

  And please take this picture as a sign of my gratitude

• FFMPEG - Instructional video combining letters to a background to form a word

  6 juin 2020, par Knide

  I'm trying to help with coding a FREE site for instructional video for kids on how to write in australian. To help with the current pandemic that we are experiencing right now.

  



  Anyway, I'm new to ffmpeg and would like to do the letter combinations programatically using it.

  



  So basically I have a form where teachers or parents can enter a word, and I have video instructions for each letter, and would combine them to form the word.

  



  Example : Dog

  



  This is the background :

  These are the letters :

  



  D - https://drive.google.com/file/d/1DHa1sZ7mklY1p3lquD8h5kTbXaZmtB_z/view?usp=sharing

  



  o - https://drive.google.com/file/d/1Ytwq_3l7x0vRDMEpZpmFjT9QNICYWH_D/view?usp=sharing

  



  g - https://drive.google.com/file/d/16jcOsrSbMSbsk2vsqeMXv9Cc4Uss7qtj/view?usp=sharing

  



  And the output would become :
https://drive.google.com/file/d/1RT38IOwXsL9kW9mj41KrxwfI_kdZy45j/view?usp=sharing

  



  If you could help with supplying what ffmpeg code we could use to have the output video, that would be great.
