How to Check RTMP Live stream is on or off

Question

I want to check RTMP live stream is on or off for mic.

I have used RTMP DUMP

exec("/usr/bin/rtmpdump -V -v -r rtmp://www.exapmle.com/etc./13/mic1 -o /tmp/rtmp-checker.log 2>&1", $pp);

I have found this trick from http://blog.svnlabs.com/how-to-check-rtmp-source-stream-is-live-or-not/

But I am not satisfied with the result because it doesn't always work, and generates a random string as a result.

![So some time i am facing this type of error. any perfect solution for this.?][1] [1]: http://i.stack.imgur.com/ZrTco.png

I'm looking for solutions with ffmpeg, or something else.

You can use ffprobe:

ffprobe -v quiet -print_format json -show_streams rtmp://example.com/stream

You'll get a return code 1 if the command failed or 0 and a JSON string containing the detected streams on success:

{
    "index": 1,
    "codec_name": "aac",
    "codec_long_name": "AAC (Advanced Audio Coding)",
    "profile": "LC",
    "codec_type": "audio",
    ...
}

This is a basic test, if you want to go further than that you could download a few seconds of the stream, validate it with ffprobe, run silencedetect on it etc.
