This creates issues when an outgoing stream is sendonly or<br>recvonly as the stream state of the inbound channel will be the same<br>as the stream state of the outbound channel.<br><br>Now the stream state is flipped for the streams of the 2nd channel in<br>ast_unreal_new_channels if the outgoing stream topology is recvonly or<br>sendonly.<br><br>ASTERISK-29655<br>Reported by: Michael Auracher<br><br>ASTERISK-29638<br>Reported by: Michael Auracher<br><br>Change-Id: I0cea29635bb20b7bf7fd0fb95498cd44dab98fbf<br>---<br>M main/core_unreal.c<br>1 file changed, 23 insertions(+), 8 deletions(-)<br><br></pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;">git pull ssh://gerrit.asterisk.org:29418/asterisk refs/changes/19/18419/1</pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;"><span>diff --git a/main/core_unreal.c b/main/core_unreal.c</span><br><span>index a79fca4..d43272c 100644</span><br><span>--- a/main/core_unreal.c</span><br><span>+++ b/main/core_unreal.c</span><br><span>@@ -1168,7 +1168,9 @@</span><br><span> struct ast_assigned_ids id1 = {NULL, NULL};</span><br><span> struct ast_assigned_ids id2 = {NULL, NULL};</span><br><span> int generated_seqno = ast_atomic_fetchadd_int((int *) &name_sequence, +1);</span><br><span style="color: hsl(0, 100%, 40%);">- struct ast_stream_topology *topology;</span><br><span style="color: hsl(120, 100%, 40%);">+ int i;</span><br><span style="color: hsl(120, 100%, 40%);">+ struct ast_stream_topology *chan_topology;</span><br><span style="color: hsl(120, 100%, 40%);">+ struct ast_stream *stream;</span><br><span> </span><br><span> /* set unique ids for the two channels */</span><br><span> if (assignedids && !ast_strlen_zero(assignedids->uniqueid)) {</span><br><span>@@ -1186,14 +1188,27 @@</span><br><span> id2.uniqueid = uniqueid2;</span><br><span> }</span><br><span> </span><br><span style="color: hsl(0, 100%, 40%);">- /* We need to create a topology to place on the first channel, as we can't</span><br><span style="color: hsl(120, 100%, 40%);">+ /* We need to create a topology to place on the second channel, as we can't</span><br><span> * share a single one between both.</span><br><span> */</span><br><span style="color: hsl(0, 100%, 40%);">- topology = ast_stream_topology_clone(p->reqtopology);</span><br><span style="color: hsl(0, 100%, 40%);">- if (!topology) {</span><br><span style="color: hsl(120, 100%, 40%);">+ chan_topology = ast_stream_topology_clone(p->reqtopology);</span><br><span style="color: hsl(120, 100%, 40%);">+ if (!chan_topology) {</span><br><span> return NULL;</span><br><span> }</span><br><span> </span><br><span style="color: hsl(120, 100%, 40%);">+ for (i = 0; i < ast_stream_topology_get_count(chan_topology); ++i) {</span><br><span style="color: hsl(120, 100%, 40%);">+ stream = ast_stream_topology_get_stream(chan_topology, i);</span><br><span style="color: hsl(120, 100%, 40%);">+ /* We need to make sure that the ;2 channel has the opposite stream topology</span><br><span style="color: hsl(120, 100%, 40%);">+ * of the first channel if the stream is one-way.
