Actually, it might indeed be a memory problem: a couple of secondary windows are created (and closed with exit) until I get a bunch of memory error messages, obviously one error message per attempt to open an additional window.

It's possible that PM (including the PM drivers) has some problem allocating memory. Potentially, because they have to allocate from some limited memory pool or region.
I have had success by decreasing the disk cache. This is a lack of kernel memory. In multiprocessor machines, the error message is not issued and the system is frozen.

With the already mentioned config and with the ORIGINAL pmmerge, I do not get a hang on either testcase.
However, teststart2 eventually reports this:

SYS0008: There is not enough memory available to process this command.
All available memory is in use.

However, I cannot see memory depleting, therefore I think the root cause if something else. In any case, this seems to be a bug in the REXX interpreter.

What I can also see for testcase2 is that the initial window does not properly draw which might be a PM problem.
If this stuff crashes for you then there might be an SMP issue with PM (as I am only running on one core). I wouldn't be surprised.
Thank you for the error message! This is a very important point that I could not get on the SMP system. Perhaps another process is trying to still use the memory that is no longer left. And there is freezing.

I offer two tests. Both of me freeze any system. I wonder how it will be with you?

Tests go through 10 000 cycles and stop in a good case and freeze earlier in a bad one.

Everything works great on two different computers. One of them is a server in constant uptime.

I believe that a successful build with AVX is an accident and I suggest disabling the AVX code until the link is fixed.

Hi, Dave

This version doesn't work for me...

And yet my assemblies are working.

There's a new version uploaded to netlabs-exp. To quote,
Quote
I've uploaded a new version 4.2.2-4 to netlabs-exp with -fno-common --disable-avx2 --disable-avx512. Note that I still use --disable-avx2 because of my current assumption that it is not safe to generate AVX2 code w/o a proper alignment support from GCC (see my comment above). I guess that it works for you now just by accident.

Closing this. Please feel free to reopen if the new RPMs don't work for you.
untested here.

This FFmpeg plays videos fine on my system, CPU supports AVX, OS/2 kernel which doesn't.
Yes of course. So everything will be, if the kernel does not support AVX, then this code is not included and another algorithm works that does not require special alignment.
But if the kernel supports AVX (this is an OS4 kernel), then the AVX code branch will turn on and a trap will appear.
If you disable AVX support during compilation, then the code will work on both the standard kernel and OS4.

Dll kit to support streaming video Seamonkey and Firefox for OS / 4 kernel. Disabled AVX support. Failed to get this set of commands to work with the "-fno-common" key.

Dariusz,

I have installed:
1. SDL2 2.0.12-2
2. libvorbis 1.3.7-2

Possibly needed packages SDL2_*
I also have them installed.

Hi Igor,

Do you have a quick pre-requisites summary?

I ask b/c trying on non OS4 kernel (assuming here that it runs w/o the AVX instructions in such a scenario) shows the following:

Code: [Select]
[G:\test\ffmpeg_avx]ffmpeg
SYS1804: The system cannot find the file VORBIS0.

...so clearly a missing DLL.

Thanks!

Hi Dariusz,

Please install libvorbis via ANPM.
You can also use yum, but I don't know what the package is called there. Perhaps the same.

This is a version of ffmpeg compiled with AVX support and correct alignment. When launched with the OS / 4 kernel, it takes advantage of the AVX instructions of modern processors.

I found that one as well, but when installed it claimed to be expired.  So not sure if I got ahold of a bad one?
I'm sorry, but I have no way to check it at all. No equipment available...

I have the SIO2K version 11-14-00 - Beta 014 with beta tester key (256 ports). If there is a need and permission from Ray, I am ready to post it.

@Igor, looks like you don't have libevent installed.
Thank you very much! Started!
Please remove broken AVX support!
