• Begin stream simple mp4 with ffserver

  19 février 2015, par Ara Deonas

  I want to stream a mp4 and for this I read about ffserver.
  So I search and read ffserver documentations but still cant stream a simple file.
  For this I done these :
  1-A win 8 and last VLC installed.
  2-A Ubuntu 13 with last ffmpeg package.
  3-A ffserver.conf file saved to /etc/ and copied from http://ffmpeg.org/sample.html (I just copy text in a new file).
  4-Run this command : ffserver -f /etc/ffconfig.conf and this is result :

  avserver version 0.8.13-6:0.8.13-0ubuntu0.13.10.1, Copyright (c) 2000-2014 the Libav developers
  
    built on Jul 15 2014 13:53:49 with gcc 4.8.1
  
  Tue Feb 10 07:29:07 2015 AVserver started.

  5-Check http://localhost:8090/stat.html and server status is OK.It shows me 4 stream : test1.mpg,test.asf,stat.html,index.html.
  6-Run this command : ffmpeg -i test.mp4 http://localhost:8090/feed1.ffm and this is result :

  7-I look at error and I can not find why this happen and where I go wrong !

  Until now I read many sample and tutorials about ffserver but most of them is about live streaming but I just want to stream some mp4 files.

  EDIT :

  I installed real ffmpeg like this link : http://askubuntu.com/questions/373322/how-to-replace-avconv-with-the-real-ffmpeg-and-have-it-work-right but same error (Just change ppa to ppa:mc3man/trusty-media for last release) :

  Can any one give me exact commands that I should run for test ?
  (I know this is like beginners problem but I read doc and test everything as I can but still no luck)

• Firefox doesn't play mp4 file in HTML5 video

  21 janvier 2016, par Developer

  I recorded a video with my mobile which had the format ".mp4". Now if I load that video in HTML5 video tag, I get an error HTTP "Content-Type" of "video/3gpp" is not supported. Why does Firefox consider the file as 3gpp although it is an mp4 file ?
  If I log the file properties when it is loaded on to browser, I see the following

  { name: "test.mp4", lastModified: 1434536249000, lastModifiedDate: Date 2015-06-17T10:17:29.000Z, size: 41151959, type: "video/mp4" }

  This means firefox identifies the type as mp4 only. But doesn’t play it giving the error HTTP "Content-Type" of "video/3gpp" is not supported.

• Read metadata with FFMPEG

  18 février 2015, par Martin Delille

  I’m looking for a way to print a video or audio file metadata using FFMPEG.

  I tried the following command :

  And got the following result :

  At least one output file must be specified

  There should be a timecode that I can’t see.

  Any ideas ?
