• video hosting with PHP api or PHP script for social network project

  17 avril 2014, par al404IT

  I have a project for a small social network where user can upload their videos, video should not be longer than 1 or 2 minutes but they need to be private and related to user that uploaded.

  Since uploaded video may be in many different format I have two options :

  • upload video and use ffmpeg to process them, can i find any PHP script that does that ? PROS I have my files on my server and I'm not dependent from third party CONS I guess is a real intensive task and I may need a quite good noting plan since the beginning of this project

  • use a video hosting service that provide API to upload and process video, i actually find vzaar.com that may seems to do what I need. PROS Scalable CONS I rely on third party for my contents

  since the project is a small social network it may be interesting this too opusphp.com, but i never user or read about

  can Vimeo PRO suite my needs ? Other suggestions ?
  In future it may be necessary to add a basic video editing function to trim uploaded video setting starting and ending point

• AVPlayer currentTime not match with the displayed frame after many seeking. (HLS Stream)

  26 août 2022, par D.Bence

  I have a m3u8 file which i want to use with HLS.
link to m3u8 file

  


  My problem is that when i seek many times, the currentTime not match with the displayed frame. I experience that, the more seeking there is more difference. (it's like a constant +offset)

  


  Our use case is very timing sensitive, we need to stop the videos at specific positions. For this we use the following code :

  


  [_player addBoundaryTimeObserverForTimes:times
      queue:dispatch_get_main_queue()
      usingBlock:^{
            weakSelf.player.rate = 0.0;
            // The time is correct here, but the displayed frame is not sync with this time
            CMTimeShow(weakSelf.player.currentTime);
      }
]   


  


  I read that AVURLAssetPreferPreciseDurationAndTimingKey can help, but the currentTime still wrong.

  


  NSDictionary<nsstring> *options = @{AVURLAssetPreferPreciseDurationAndTimingKey:@YES};&#xA;AVURLAsset *urlAsset = [AVURLAsset URLAssetWithURL:url options:options];&#xA;AVPlayerItem *item = [AVPlayerItem playerItemWithAsset:urlAsset];&#xA;</nsstring>

  


  I also read that there is a problem with the m3u8 itself. (for example wrong GOP size.)

  


  What is the reason for the incorrect currentTime, and how can i fix this ?

• ffmpeg : Time information does not match video duration

  8 novembre 2017, par Harry Developer

  I’m using tvheadend to record broadcasts to disc (running ubuntu). Later, I’m playing the files using players like MX Videoplayer or IJK player. Sometimes, the time information of the media files is weired. E.g., using

  ffprobe -i some-file.ts

  shows a lenght of 10 hours or even 20 hours, although the recording is only 2 hours long. Is this a ffmpeg bug ? What can be done to get the correct media length ?

  Here is the ffprobe output of the original file after recording it on disc :
