How to Check RTMP Live stream is on or off

I want tocheck 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 Satisfy with result because some time its not working and generates random string as result.

So some time i am facing this type of error. any perfect solution for this.? IF YOU have any other solution Using FFMPEG OR OTHER then you are most welcome.

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.

    • You can try lowering -probesize (in bytes, default 5 mb). If it still gets stuck forever then the alternative is to use the linux timeout command: timeout 10s ffprobe .... It will return 124 if the command timeouts, in which case you raise an alert and check the stream.
    • Is it nessesary to include the -print_format json and the -show_streams options? After a some tests it looks like to me that the method works even if you rely on the exitcode exclusively, while omitting both options.

    • @GergelyLukacsy It's not necessary if you don't need stream information. The question was about a microphone stream thus the check for an audio stream.

Warm tip !!!
