Crash when WifiDisplaySink.cpp:652 CHECK_EQ( err,(status_t)OK)

I use samsung Note2 as source . also I know the Note2 with hdcp, so the wfd failed. the sink crash when WifiDisplaySink.cpp:652 CHECK_EQ( err,(status_t)OK). The sink application crash seams not so friendly for user, how to avoid the application crash? thanks a lot.

Crash in onQueueAccessUnit

I'm working on a HDMI dongle running 4.4.2. I'm getting following error.

I have put more debug logs to check. And what I see is that, AMessage of accessunit with track_no 0, is not getting a format in the first message. So It doesn't get registered in DirectRenderer, and hence it crashes.

Can you point to cause of such a problem? (I'm using Nexus 7 2013 as a source) Thanks a lot !

Merging with with AOSP 4.4.2 as a sink

I am trying to patch 4.4.2 with your 4.4.2 branch.

I'm able to match dependencies, and build the systemimage. Now while testing the app (Mira4U), I have found following issues. (I'm testing this as a WFD sink)

1. Without Special Mode
   /NetworkSession( 2609): connecting socket 52 to 192.168.49.7:7236
   I/WifiDisplaySink( 2609): We're now connected.
   E/WifiDisplaySink( 2609): Invalid server_port description '19000'.
   F/WifiDisplaySink( 2609): frameworks/av/media/libstagefright/wifi-display/sink/WifiDisplaySink.cpp:652 CHECK_EQ( err,(status_t)OK) failed: -1007 vs. 0
2. WIth Special Mode on -
   E/NetworkSession( 3357): Recvfrom failed, 199/200 retries left
   I/TimeSyncer( 3357): timed out, sending another request

TimeSyncer keeps on trying to recieve content, and times out.

Can please help in solving this?
