• how to apply video filter in ffserver live streaming

  28 mai 2015, par Razack

  We are live streaming from camera in to ffserver through ffmpeg. We are converting the live streaming into side by side (SBS) using ffmpeg stereo3d filter. we have no problem getting the required output directly playing in MPlayer. When we stream through FFServer into a player what we get is not side by side but a single.
  ffmpeg -i source.mp4 -vf stereo3d=sbsl:abl http://x.x.x.x:8090/feed1.ffm
  Thanks for your help

• Live Streaming App iOS

  23 août 2016, par Jay Gajjar

  I am trying to develop a live-streaming application like the meerkat app, where user A can broadcast a live stream while other users are able to watch it. I am having trouble understanding the architecture and mechanisms used to upload video to a server. Currently, I am using a dedicated server with FFMPEG installed on it. I also know FFServer can be used to perform RTSP communication, but I am still unclear how to do this. Can anyone guide me on this ?

  I would like to know how to upload videos to a server or whether there is another way to perform a live stream. Open source frameworks are welcome.

• FFmpeg Live streaming, capture card avisynth/graphedit

  19 décembre 2013, par diegonaranjo

  I´m stuck in a problem with a test doing multicast streaming from a Viewcast Osprey 700e HD using ffmpeg.
  The thing is that I´ve to use avisynth(with graphedit) for ffmpeg recognize the card. The streaming has no ending time,
  is a live channel for IPTV.
  The script is working well, but the problem is the avisynth config, because I have to specify the countframe option,
  i think this is for the duration of the clip, but I need an infinity streaming.

  The is script is :

  ffmpeg -i espnhd.avs -rtbufsize 100000k -r 30 -c:v mpeg2video -b:v 5120k -s 1280x720 -g 100 -q:v 2 -c:a ac3 -b:a 256k -f mpegts udp ://239.192.42.61:1234

  The espnhd.avs file is :

  v=directshowsource("espnhdv.GRF", pixel_type="YUV", framecount=1000000, fps=30, audio=False, convertfps=false)
  A=directshowsource("espnhda.GRF", fps=30, framecount=1000000, video=False, convertfps=false)
  AudioDub(V, A)
  loop()

  When i run the application, work fine but the streaming ends when 1000000 frames it´s encoded...
  If i dont specify framecount, ffmpeg doesn´t start with the following error, can´t determine the duration of the clip.

  Is there any way to specify an inifinity duration on avisynth ?

  The streaming stops at 1:57hs. I took the end fo the logs :

  I really appreciate some help.
