Killing RTMPsrv/RTMPdump inside Windows

I have successfully created a batch file to open RTMPDumpHelper and browser.

The problem I have is I tried to use taskkill and Cygwin tools to kill rtmpsrv and rtmpdump.

The problem is it apparently only kills rtmpsrv but not the rtmpdump that is started.

I randomly use rtmpdump in other batch files around same time so I can't just try killing any rtmpdump.

Anybody know if there is a way to watch for the exact PID or something, cause only way so far is kill it when I get a chance causing unnecessary extra recording.

Re: Killing RTMPsrv/RTMPdump inside Windows

If you get my build of RtmpSrv, you can use the "--printonly" option.

Code:

$ rtmpsrv --help

This is just a stub for an RTMP server. It doesn't do anything beyond

obtaining the connection parameters from the client.



-h, --help              Prints this help screen.

-c, --port port         Overrides the port in the rtmp url

-i, --printonly         Print RtmpDump command and exit

-z, --debug             Debug level command output.

-N, --version           Print version information and exit

I see how your rtmpsrv works but I'm not quite sure how I can still kill it afterwards.

I mean I still think I would have to find some way to find out exactly which rtmpdump is running for my recording and kill only that one.

It is clear you have misunderstood the "--printonly" option. It does not invoke RtmpDump. Running RtmpSrv with the printonly option merely prints the first RtmpDump command detected and exits.

Well I understand that part but I was temporarily confused on how to kill the rtmpdump I start afterwards with the output.

Cygwin has long known issues with non-Cygwin binaries, AKA RtmpDump. If you want to kill RtmpDump with Cygwin, you need to do one of these

Quote:

# Instead of invoking like this
rtmpdump -o a.flv -r rtmp://server.com/app/playpath
# Invoke like this, then hit Ctrl+C to stop
timeout 1d rtmpdump -o a.flv -r rtmp://server.com/app/playpath

# Set RtmpDump to simply stop after certain time
rtmpdump -o a.flv -r rtmp://server.com/app/playpath -B 10

# Invoke RtmpDump under cmd.exe instead of Bash
rtmpdump -o a.flv -r rtmp://server.com/app/playpath

# Compile RtmpDump as a Cygwin binary instead of Native Windows binary
rtmpdump -o a.flv -r rtmp://server.com/app/playpath

# Kill RtmpDump using Cygwin commands
ps -W | awk /rtmpdump/'{print$4;exit}' | xargs kill -f

# Use Windows Task Manager to kill
rtmpdump.exe

Re: Killing RTMPsrv/RTMPdump inside Windows

Thank you so much.

I finally came up with a working idea from your solutions.

I realized with "ps -W" I can find out exactly which rtmpdump is running and kill only the one going to RTMPDumpHelper and not the other one on the system recording other stuff at any given moment.

I wrote a fix for this years ago.

Seems like it may not have been committed, unfortunately.

Re: Killing RTMPsrv/RTMPdump inside Windows

I use Cygwin as well. I often have multiple streams running, so "ps" doesn't do it for me. I found the following command allows me to pick the right rtmpdump stream to kill:

WMIC.exe PROCESS get CommandLine,ProcessId

I parse out the lines and grep the particular stream I want dead. Then kill -9 on the correct pid works pretty well for me. The only downside is the (partial) stream doesn't get finished, so stream viewers will think it's a live stream. I'm sure a quick trip through ffmpeg would clear that up, though. (I haven't actually tried, cause I throw away the streams I kill.)
