close/kill another Windows process which is started by run a .bat in Qt app
-
You can run this command without cmd.exe, that's my point...
-
No.
process->start("gst-launch-1.0", QStringList() << HERE_PUT_THE_PARAMETERS_AS_LIST); -
@jsulm With the help of GStreamer Library?
@Vijaykarthikeyan
Don't understand. @jsulm is just asking why you usecmd /c ...at all? Use QProcess::startCommand() directly on your string starting with"gst-launch-1.0 ...". Then you don't have acmdprocess and agst-launch-1.0one to deal with.@jsulm
The user probably doesn't want to split his string into lots of separate arguments to pass tostart():) That's why I suggest he might want to usestartCommand(). -

that's why i didnt know about this command

Always helps if you tells which version you are using for any question!
To use
start()then (withoutcmd /c) you must chop your line up into separate arguments at every (non-embedded) space. probably including each of those!which are being used as "pipes" on the command passed togst-launch-1.0. Do so manually in code source, or maybe useQString::split()on space if you want. I think QStringList QProcess::splitCommand(QStringView command) is available to you in 5.15. [Yes, it was introduced at 5.15 if you want to use it.] -

-
Why? I don't know.
Windows/DOS has ataskkill <pid>command, I believe. You could issue that via anotherQProcess(try it first from command line). I don't know if that will work whenQProcess::kill()does not. I do not know whethergst-launch-1.0is itself a "wrapper" for spawning other processes. -

@JonB ok..understand..Can you please calrify one thing.. Will terminatinf the QProcess will terminate the process pointer or the process which is triggered by the QProcess?
@Vijaykarthikeyan It should
deleteterminate the process created on theQProcessobject, i.e. just what you would expect.
