• FFmpeg make mpeg2 ts without discontinuity

  31 mai 2012, par user1427162

  I have many MOV files recorded with iPhone and I want to convert them to mpeg2 TS. I want to use them for live video streaming with HTTP Live Streaming protocol.

  I set my iPhone to continiously send MOV files to server. Every video clip is 5 seconds long. I want to make mpeg2 TS out of them and add their urls to m3u8 playlist.
  I managed to do all of that, but when I try to play the stream VLC player plays only first two files in playlist, and last file in playlist at that moment.
  I searched the internet and I think this has something to do with discontinuity.

  Is there any way to convert multiple MOV files into multiple mpeg2 TS segments without discontinuity ?

  Or maybe I'm doing something else wrong ?
  Here is my ffmpeg command :

  ffmpeg.exe -i input,MOV -f mpegts output.ts

  and here is my m3u8 list :

  #EXTM3U
  
  #EXT-X-PLAYLIST-TYPE:EVENT
  
  #EXT-X-TARGETDURATION:10
  
  #EXT-X-MEDIA-SEQUENCE:0
  
  #EXT-X-MEDIA-SEQUENCE:0
  
  #EXTINF:10,
  
  fileSequence0.ts
  
  #EXTINF:10,
  
  fileSequence1.ts
  
  #EXTINF:10,
  
  fileSequence2.ts

  Thanks in advance

• Preview video in android before saving to phone

  13 novembre 2014, par Zoe

  I’m in the process of creating a video editor for android.
  I am loading .mp4 videos into a timeline, where each rectangle in the timeline represents an imported video and I can drag/drop and rearrange these videos etc before saving the new .mp4 to my phone.

  I’ve been using mp4parser to do this, however I have ffmpeg loaded too but have avoided using this as I’m not too familiar with c++

  I have a space for a video player in my app. The idea is to have a seek line that can be dragged along the timeline as you are editing, and I want the player to be able to play a
  the edited video at the given point.

  However, the only examples on how to implement video players in android require you to load this video from your phone to play it. I was thinking I could just play the loaded videos separately but one after another giving the impression you’re watching a whole video, but I’m later planning to add functionality to include transitions and subtitles to videos which you would not be able to preview using this method.

  Any ideas on how about I can go about implementing a video player to preview the media whilst editing ?

  Thank you.

• how to use x264 dll in another project

  5 août 2014, par Hadi Rasekh

  enter code here I want to use x264 in my project. There is some line in the code said :

  /* Application developers planning to link against a shared library version of
* libx264 from a Microsoft Visual Studio or similar development environment
* will need to define X264_API_IMPORTS before including this header.
* This clause does not apply to MinGW, similar development environments, or non
* Windows platforms. */

  But I don’t get this line :
  define X264_API_IMPORTS before including this header

  We can create x264 dll by its configuration and make

      ./configure --enable-shared
  
      make

  but I can not use the dll in my Qt Project.

  I can make my own dll (in another code) and use it in the project.
  But when I start to use x264 dll in my project I get the following error :

      C:\DataHiding\SourceCode2\GUI\DataHiding\mainwindow.cpp:10: error:
  
      'pulldown_frame_duration' was not declared in this scope
  
      qDebug() << pulldown_frame_duration[1];
