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.
What CPU are you on?
There is some complexity regarding the amount of threads and
process groups on windows, see:

Do you even have a processor that will utilize 64 cores?
I recommend trying with smaller values and see where "windows make"
starts to fail.
Regards,
S Srihari

Hi,
I was building ffmpeg through windows. While I was able to successfully
able to build for smaller number of threads, for larger number of
threads I
faced an issue
The commands I used were
bash ./configure --arch=x86 --target-os=mingw32 --disable-x86asm
make -j <no_of_Threads>
While building with 4 Threads the build was successful

While building with 64 threads, I faced the following error,

Please don't use images for plain text. It's hard to access and barely
legible.
Please could you check this issue. Thanks
You probably just ran out of RAM or something. Highly unlikely that this
is an issue with ffmpeg.
