Is it possible to pause an encoding in MeGUI?

[comomolo]

I see a pause icon in the main queue window, but when I click on it, the encoding still goes on.

I see a pause icon in the main queue window, but when I click on it, the encoding still goes on.might pause after the current pass.

[comomolo]

The current pass will take 8 hours... I need to pause it in the middle of this pass. Is that possible at all?

[Sirber]

As far as I know, no. You cannot pause a CLI.

I presume you're using x264 (I really cannot imagine why somebody wouldn't tell that to begin with.. how is anybody but you to know what you are doing if you don't tell?), so in that case, x264.exe will keep on going for a few hundred frames (and depending on your settings, computer, etc. that can take a long while) before it finally rests.

Although, since pause doesn't mean you can close megui, what's wrong with low priority? That'll yield every CPU cycle other apps need but it'll still keep going and once no other software uses your CPU cycles it'll go on full speed again without you having to do anything about it.

@Doom9

How does your "pause" exactly work?

[Doom9]

stop reading from the stdout/stderr pipes.. that pauses every software that prints progress to stdout/stderr I know of (in case of x264, it takes excessively long but it still works).

[Sirber]

hum.... don't think I can do that with TDosCommand (Delphi)...
thanks for the hint though! :D

Hey, hold your horses!! I simply didn't think that was an important bit of information. I still think it isn't, but you're the developer, so yes, you're right, I'm using x264.

All right. I'll see if I can still work on Golive (which takes A LOT of memory and CPU) while x264.exe is executing in low priority.

Just out of curiosity: Long time ago I was a Silicon Graphics user and IRIX had a command to pause any process (Ctrl-z, if I remember well) and then other commands (fg and bg) to bring it back to life. Aren't there any similar commands in Windows? Again, this is just curiosity.

Thanks for your answers.

DOS and Win32 cmd shell have pause too; what do you think the pause key is for? :p But a lot of programs ignore it now, maybe it's not part of current stdc libs. But no way to break into a command and run the shell before resuming. Neatness.

Could be cool if someone could hack this in TDosCommand :D

You can suspend a process by calling SuspendThread on all its threads.
There is a command line tool. http://www.sysinternals.com/Utilities/PsSuspend.html
