FFmpeg: NetStream.Play.StreamNotFound for RMTP stream

Question

I want to take snapshots of the RTMP video stream periodically. I see the rtmp video stream using VLC. This is the rtmp url:

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

I use the following command to capture snapshots, according to the official FFmpeg website here :

 ffmpeg -i rtmp://antena3fms35livefs.fplive.net/antena3fms35live-live/stream-antena3_1 -f image2 -vf fps=fps=1 out%d.png 

The command produces the following output:

Closing connection: NetStream.Play.StreamNotFound rtmp://antena3fms35livefs.fplive.net/antena3fms35live-live/stream-antena3_1: Unknown error occurred 

I tried this with other rmtp streams, but I still get the same error.

What could be the problem? Thanks!

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

I know that other / older versions used "librtmp" for rtmp connections, which require additional options for the stream url. See ffmpeg docs here: ffmpeg librtmp documentation

And librtmp docs here: librtmp documentation

For an unprotected live stream, you can try specifying the stream URL and adding "live = 1" in quotation marks:

 ffmpeg -i "rtmp://antena3fms35livefs.fplive.net/antena3fms35live-live/stream-antena3_1 live=1" -f image2 -vf fps=fps=1 out%d.png
