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, 2 insertions(+), 2 deletions(-)
