Subject: [PATCH] Devices are expected to honour the CA field. Without this
 patch there is no way to tell a VDR that it may not use streamdev for a
 specific channel.

+# The cannels.conf ca field can be used to bind a channel to a specific
+# device. The streamdev-client does not consider this information, so
+# there's no way to keep VDR from using streamdev for a specific
+# channel. Apply this patch if you need this feature.
+#
+# This fix should probably become part of streamdev. However as it
+# changes the behaviour of streamdev, I decided to keep it as a separate
+# patch until there is something like a new official streamdev release.
