• ffmpeg convert rtp to mp4(http) streaming

  24 février 2016, par Asoul

  I want to use ffmpeg for transcoding RTP streaming to MP4(HTTP) streaming, so I can play in html video tag,

  but I can only transcode to flv format successfully.

  Below is my settings :

  [/etc/ffserver.conf]

  ...
  
  
  
  <feed>
  
    File /tmp/feed1.ffm
  
    FileMaxSize 5M
  
    ACL allow localhost
  
  </feed>
  
  
  
  <stream flv="flv">
  
    Feed feed1.ffm
  
    Format flv
  
    VideoFrameRate 40
  
    VideoBitRate 128

  </stream>
  
  
  
  <stream mp4="mp4">
  
    Feed feed1.ffm
  
    Format mp4

  </stream>
  
  
  
  <stream avi="avi">

  avutil/error : Add HTTP 429 Too Many Requests AVERROR code
  This is a common error code from e.g. CDNs or cloud storage, and
  
  it is useful to be able to handle it differently to a generic
  
  4XX code.
  Its source is RFC6585.

• FFmpeg code not working on http url for thumbnail extraction

  1er août 2014, par user2240379

  I am trying to extract thumbnail from sharepoint 2013 video library. I found a link which can extract using ffmpeg. this is the link :
  [How can I save first frame of a video as image ?

  filename = "http://siteurl/" + items["FileRef"].ToString();

  When i replaced the input file with sharepoint site url and video name then it does not produce any thumbnail. I also gives error on

  ffmpeg.Start();
  
          ffmpeg.WaitForExit();
  
          ffmpeg.Close()

  I would like to understand how make it work for http url.
  If it is not possible to use url in ffmpeg can anyone suggest another method to achieve thumbnail.(as i want the thumbnail to be set automatically using 1st frame from of video if it not set manually)
