From e6bd5b41935f125bf43e030dcb909c3537d33b31 Mon Sep 17 00:00:00 2001 From: David Svensson Fors Date: Tue, 3 Sep 2019 10:38:13 +0200 Subject: [PATCH] miniobject: free qdata array when the last qdata is removed In cases with many long-lived buffers that have qdata only very briefly, the memory overhead of keeping an array of 16 GstQData structs for each buffer can be significant. We free the array when the last qdata is removed, like it was done in 1.14.
