Hi, Thanks for the reply. I checked the memory usage while building ffmpeg with 64 threads. The machine I tested has 128 GB ram. While I tested it I found that maximum memory utilized by the build of ffmpeg was 17GB. Still the build throws up error semaphore or child process wait (Error 87 : The parameter is incorrect). Hence could you check on the same please. I have attached screenshots of memory utilized from the task manager.
