+Subject: [PATCH] Don't try to acquire buffer when src pad isn't active
+
+From: =?UTF-8?q?Enrique=20Oca=C3=B1a=20Gonz=C3=A1lez?= <eocanha@igalia.com>
+
+This solves a race condition when setting the pipeline from PAUSE to
+NULL while the decoder loop is still running. Without this patch, the
+thread which interacts with the decode sink pad gets blocked here:
+
+  gst_element_change_state()
+  gst_element_change_state_func()
+  gst_element_pads_activate() --> Deactivating pads
+  activate_pads()
+  gst_pad_set_active()
+  gst_pad_activate_mode()
+  post_activate()
+  GST_PAD_STREAM_LOCK()
+
+while gst_omx_port_acquire_buffer() gets stalled forever in
+gst_omx_component_wait_message() waiting for a message that will never
+arrive:
+
+  gst_omx_video_dec_loop()
+  gst_omx_port_acquire_buffer()
+  gst_omx_component_wait_message()
