Hi, when I connect to the Piracast, 1/2 the time my Moto X shows that it is mirroring, but there is no picture, But the other half of the time, I get socket.error: [errno 113] No route to host

Does anyone have any idea how to fix this.

Thanks!

This is the last log entry, after that the following information appears and the system freezes.

Its a plain raspbian image no other tools or packages was installed.
Tried also a completly new flashed image - same same.

Some System information:

Any hints?
Thanks in advance.

Hello,

there is an error in line 140
Old: match = re.search(r'Session: (\d_);', m6_rsp)
New: match = re.search(r'Session: (\d_)', m6_rsp)

This solved the

File "/home/pi/piracast/scripts/sink.py", line 143, in source_connect
s.send(m7_req.format(ip, match.group(1)))
AttributeError: 'NoneType' object has no attribute 'group'

error for me on a Sony Xperia Z1.

The M6 Response does not contain a ";" between the Session: and the Transport: part. So, the match.group(1) does not contain any value with the old line 140. With the new line 140, it now contains the Session ID and that worked for me.

When I try to close piracast with ctrl+c it hangs.
When I exit from the client it works fine.
Maybe exiting with ESC should also be possible?

I just skip the driver part (pi 3 has built in wifi)
Then I install isc-dhcp-server
after that copy this

sudo cp env/isc-dhcp-server /etc/default
sudo cp env/dhcpd.conf /etc/dhcp/
sudo cp env/interfaces /etc/network/interfaces

After compile successful and reboot
The wifi and ethernet ruined
NO WIFI INTERFACE FOUND in network setting
I thick is the network config files overwrited in dhcp server install part so wifi and ethernet not work anymore

Sorry for my bad English

sx_mgmt_video_decoder.c:364
slice_start_find : Assertion '0' failed.

Commenting out or deleting this line helps as workaround for the Sony Xperia Z1.

Any ideas or hints to solve this problem?

Hello,

after updating the piracast files today, I had a lot of problems.
1.) The core app does not start: I had to change from
cmd_launch_core_app = 'nice -n -20 ./core'
to
cmd_launch_core_app = 'nice -n -20 ./core 1>/dev/null &'
to get the core app started.

2.) After Ctrl+C the started core app does not stop. A kill PID is needed.

3.) File "/home/pi/piracast/scripts/wfd.py", line 128, in p2p_peer_devaddr_get
mac = '%s%s:%s%s:%s%s:%s%s:%s%s:%s%s' % match.group(1)[0:11]
TypeError: not enough arguments for format string

I then used the old, out commented code in wfd.py.That worked for me.
#mac = match.group(1)[0] + match.group(1)[1] + ':'
# + match.group(1)[2] + match.group(1)[3] + ':'
# + match.group(1)[4] + match.group(1)[5] + ':'
# + match.group(1)[6] + match.group(1)[7] + ':'
# + match.group(1)[8] + match.group(1)[9] + ':'
# + match.group(1)[10] + match.group(1)[11]

I am seeing a following error
File "piracast.py", line102, in sink.source_connect(ip)
File "/home/pi/........./Piracast/scripts/sink.py" , line 85, in source_connect s.connect((ip,7236))

File ......in ....../python2.7/socket.py return getattr(self,sock, name)(*args)

socket.error: [Errno 111] Connection refused

I got a dx wifi dongle, and wanted to know if is there any chance it works with piracast.

I pressume the problem lies with no iwprivs, despite i installed the driver and rebooted
