+Date: Thu, 11 Feb 2021 12:25:14 +0100
+Subject: [PATCH 2/2] avcodec/libopusenc: reload packet loss at encode
+
+An estimation of packet loss is required by libopus to compute its FEC
+data. Currently, this estimation is constant, and can not be changed
+after configuration. This means an application using libopus through
+ffmpeg can not adapt the packet loss estimation when the network
+quality degrades.
+
+This patch makes the encoder reload the packet_loss AVOption before
+encoding samples, if fec is enabled. This way an application can modify
+the packet loss estimation by changing the AVOption. Typical use-case
+is a RTP stream, where packet loss can be estimated from RTCP packets.
+

+Subject: [PATCH] Screen sharing x11 fixes
+
++ We can now have a single stream in the x11grab, which can be updated to follow window resizing
++ Due to stream reinit, shm may cause memory issues and was removed
++ Adds one option (is_area) that defines if we are grabing a region of the display/window or the hole screen/window.
