• Libavfilter with ffmpeg - overlay the last X seconds

  9 avril 2012, par gphilip

  Looking at the docs of libavfilter it doesn't seem to be possible, but still, I hope you can help me.

  I want to overlay an image to a movie but only for the last X seconds of the movie. I managed to overlay for the full movie, no problem. But can I get a time when the overlay is shown ?

  I use ffmpeg with compiled with libavfilter. Any tricks to solve this ?

• Receive HLS stream and rebroadcast

  22 septembre 2020, par user9066046

  I have commercial streaming server that streams via HLS in Europe.

  


  http://europe.server/stream1/index.m3u8

  


  Now my clients in USA having some network issues due to distance.

  


  So I have deployed new server in USA. I'd like it to receive HLS streams from European server and respond to US based customers.

  


  So users can access like

  


  http://usa.server/stream1/index.m3u8

  


  It will be H265/HEVC only so RTMP is not possible. Every tutorial I see on internet is based on RTMP.

  


  I have used following config from https://docs.peer5.com/guides/setting-up-hls-live-streaming-server-using-nginx/ for reference.
