• Play video files online sequentially without delay/buffering between videos

  26 février 2015, par Marko

  Is it possible to play video online that’s made of two or more video files ?

  Since my original post wasn’t clear enough, here’s expanded explanation and question.

  My site is hosted on Linux/Apache/PHP server. I have video files in FLV/F4V format. I can also convert them to other available formats if necessary. All videos have same aspect ratio and other parameters.

  What I want is to build (or use if exist) online video player that plays video composed of multiple video files concatenated together in real-time, i.e. when user clicks to see a video.

  For example, visitor comes to my site and sees video titled "Welcome" available to play. When he/she clicks to play that video, I take video files "Opening.f4v", "Welcome.f4v" and "Ending.f4v" and join/merge/concatenate them one after another to create one continuous video on the fly.

  Resulting video looks like one video, with no visual clues, lags or even smallest observable delay between video parts. Basically what is done is some form of on-the-fly editing or pre-editing, and user sees the result. This resulting video is not saved on the server, it’s just composed and played that way real-time.

  Also, if possible, user shouldn’t be made to wait for this merging to be over before he/she sees resulting video, but to be able to get first part of the video playing immediately, while merging is done simultaneously.

  Is this possible with flash/actionscript, ffmpeg, html5 or some other online technology ? I don’t need explanation how it’s possible, just a nod that it’s possible and some links to further investigate.

  Also, if one option is to use flash, what are alternatives for making this work when site is visited from iphone/ipad ?

  Hey my name is Alisha from Norway im trying to get my RTMP server working the thing is that it works just fine but I just cant stream over it with ffmpeg I can stream to it on OBS and it works fine, but I am trying to a website where people could watch old public domain movies from the 1950 some of the films are actually pretty big lol.... anyways I detailed bellow more

  


  rm -rf /mnt/hls/loool && ffmpeg -re -i "$file" -c:v libx264 -c:a aac -b:v 300k -b:a 95k -f flv -flvflags no_duration_filesize rtmp ://lambright.xyz:1935/live/loool

  


  any work around I literally cant play the audio :( I can only hear (my source file is an MKV and 3gb )

  


  Note I had a smaller mp4 file and it did played the audio, the video isnt even playable in chrome but on VLC it is, but only a small file worked fine... its fine when I stream from my pc, but whats the point I am trying to set up my vintage 1950 serverbox :') trying to build a nice website where users could watch neat and decent old movies that are public domain if you wonder :/

  


  Another note when I am trying to play it on my iphone safari browser it does actually play parts but audio is super corrupted like you hear the audio sometimes :((
