  NetStream.Play.StreamNotFound while trying to get RMTP snapshot

  Posted by Gabriel Barreras on July 17, 2014 at 10:28 am

  Hi,
  I’m using the following command:
  ffmpeg -i rtmp://antena3fms35livefs.fplive.net/antena3fms35live-live/stream-antena3_1 -f image2 -vf fps=fps=1 out%d.png
  extracted from official FFmpeg wiki here.
  I am allowed to see the video stream using VLC with the same link. However, when using the command above, I’m getting this output:

rtmp://antena3fms35livefs.fplive.net/antena3fms35live-live/stream-antena3_1: Unknown error occurred

  What is the problem here?
  I’ve tried with other different rtmp streams and I’m still getting the same error.

  Thank you!

  I just tried your command and it worked fine for me. Maybe it is something about your FFMPEG installation? I am using version 2.4 on a Mac (tessus build).

  I know other/older versions used “librtmp” for rtmp connections, which required some extra options behind the stream URL. See ffmpeg docs here:
  https://www.ffmpeg.org/ffmpeg-protocols.html#librtmp-rtmp_002c-rtmpe_002c-rtmps_002c-rtmpt_002c-rtmpte

  And librtmp docs here:
  https://rtmpdump.mplayerhq.hu/librtmp.3.html

  For an unprotected live stream, you may want to try quoting the stream URL and appending ” live=1″ within the quotes:
  ffmpeg -i "rtmp://antena3fms35livefs.fplive.net/antena3fms35live-live/stream-antena3_1 live=1" -f image2 -vf fps=fps=1 out%d.png
