From: Brendan McGrath <bmcgrath(a)codeweavers.com> The avdec_h264 element can use 32MB per thread when working with 4K video. With 16 threads, this is 512MB, which is a quarter of the RAM available to a 32-bit application. Setting MAX_THREADS to 4 can save 384MB. --- dlls/winegstreamer/unixlib.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/dlls/winegstreamer/unixlib.c b/dlls/winegstreamer/unixlib.c index 84a946ec395..822deb21949 100644 --- a/dlls/winegstreamer/unixlib.c +++ b/dlls/winegstreamer/unixlib.c @@ -313,7 +313,11 @@ void set_max_threads(GstElement *element) if (shortname && strstr(shortname, "avdec_") && ELEMENT_HAS_PROPERTY(element, "max-threads")) { +#if defined(__i386__) + const gint32 MAX_THREADS = 4; +#else const gint32 MAX_THREADS = 16; +#endif gint32 max_threads = MIN(thread_count, MAX_THREADS); GST_DEBUG("%s found, setting max-threads to %d.", shortname, max_threads); g_object_set(element, "max-threads", max_threads, NULL); -- GitLab https://gitlab.winehq.org/wine/wine/-/merge_requests/5923
