• Add filters and effects by FFMPEG on a live program

  2 mars 2014, par M.Yazdian

  Add filters and effects by FFMPEG on a live program.
  I need to add some effects such as writing at the bottom of a live program and impose the Images of other live cameras on the main camera image through FFMPEG but when I want to add these effects and filters I have to stop FFMPEG, edit command and run FFMPEG again which is not professional.

  All other broadcasting software such as wirecast , vidblaster and others work very well while the main event is going on LIVE, you can add filters and effects without any stop start, just apply the effect and the viewer can see every think live without any interruption

  can you advice me how can I use FFMPEG and add filters and effects without any stop start, I need to just apply the effects and the viewer should see every think live without any interruption.

  Thanks

• How to generate the first few HLS playlist files for a live broadasting event ?

  1er mars 2014, par user3367166

  Knowing that HLS is based on a playlist of N segment files, how to properly generate the first (N-1) playlist files for a live broadcasting event (sliding window method) ?
   should we wait for the first N segments to be recorded, and send a complete first playlist file ? This of course works but means that there is a delay of N x segment_duration before streaming starts.
   or is there an official way of sending "partial" playlist files such that streaming starts after 1 x segment_duration ?

  I have experimented with partial playlist files : ffmpeg 2.1.3 appends new segments into the playlist as they are recorded (below). I find this a reasonable way but my ipod5 usually stops playback after the first playlist or sometimes manages to playback the first few playlists but with much choppiness, so I believe it is not a supported way. Is there any official solution ?

  1. 1st playlist file :

     #EXTM3U
     
     #EXT-X-VERSION:3
     
     #EXT-X-TARGETDURATION:8
     
     #EXT-X-MEDIA-SEQUENCE:0
     
     #EXTINF:8,
     
     segment0.ts

  2. 2nd playlist file :

     #EXTM3U
     
     #EXT-X-VERSION:3
     
     #EXT-X-TARGETDURATION:8
     
     #EXT-X-MEDIA-SEQUENCE:0
     
     #EXTINF:8,
     
     segment0.ts
     
     #EXTINF:1,
     
     segment1.ts

  3. 3rd playlist file :

     #EXTM3U
     
     #EXT-X-VERSION:3
     
     #EXT-X-TARGETDURATION:8
     
     #EXT-X-MEDIA-SEQUENCE:0
     
     #EXTINF:8,
     
     segment0.ts
     
     #EXTINF:1,
     
     segment1.ts
     
     #EXTINF:8,
     
     segment2.ts
