Question: reducing reserved stack size about ffmpeg

[Sibras]

The VS projects settings to control stack allocation are are found in the "Linker->System" section of the project properties (in this case it would be the x264 project). However by default only 1MB is allocated for the stack of each thread so 500MB seems a bit high. It is possible to programmatically control the stack allocation at thread creation time using CreateThread however none of the supplied projects use this method and just use the default project settings.

Using a standard x264 build should work fine on 32b and when doing an encode most of the new threads will be created by libx264 internally so you can try testing it using the direct x264 cli program found in the supplied repo. I will mention that when doing 10bit encodes the upstream project doesnt even support using 32bit due to memory space issues causing it to fail. That said a default 8bit encode should still function.

Thanks Matt! I've have another look and trying to create the .h264 video stream makes the stack address space grow from ~450MB to ~570MB. That's a significant jump, but it's hardly the root cause of our problems. On the other hand, we have a "Private Data" segment 1GB in size, that's probably where we should investigate.
