Information Request: Batch Processing about server

[ArcAIN6]

after a bit of searching on my own, it seems you aren't able to limit memory usage of ffmpeg.. however, you can make ffmpeg use less CPU (the bigger issue here)

from what i read, you can lower the thread count of ffmpeg by adding -theads x .. where x represents the number of cores you wish to utelize.

example:

Process ffmpeg = new Process();
ffmpeg.StartInfo.UseShellExecute = false;
ffmpeg.StartInfo.FileName = "..\ffmpeg.exe";
ffmpeg.StartInfo.Arguments = "-threads 4";  // <=== Add this line
ffmpeg.StartInfo.CreateNoWindow = true;
ffmpeg.Start();

Right, setting '-threads 1' will limit the number of threads per each ffmpeg processes.

But u still will have several conversion jobs running parallelly.
You can control the number of concurrent conversions jobs via 'maxInstances' param in batch.ini file (or enabledWorkers.KAsyncConvert param in more recent Kaltura versions).

I would u suggest to take another route - try to set the conversion jobs to lower Linux priority. This way the critical jobs will get the resources while they will be needed, and the conversion jobs will be able to exploit the full CPU resources when the critical jobs are idle. I don't know whether this is possible set up, but it is worthwhile to inquire.

thank you for the info :)
