I'm working on adding native AWS webrtc for our Android hybrid App. It works well on other smartphones but will crash on HUAWEI. When the webrtc connection succeed, App crashed. Here is the part of the Log:

The main error Info is:
E/KinesisVideoSdpObserver: onSetFailure(): Error=Failed to set remote answer sdp: Failed to set remote video description send parameters.
What I'm confused is that in sdp offer, the codec be like:
a=rtpmap:98 VP9/90000
But in sdp answer I found:
a=rtpmap:0 H264/90000
Is this the main cause of the crash? On other smartphone(I tried Xiaomi, Samsung, Vivo),this two sdp lines are both H264. But HUAWEI do support H264, this is my HUAWEI Mate 20 codecInfo:

And I also try to read webrtc code, I found this in MediaCodecVideoDecoderFactory:
private boolean isH264HighProfileSupported(MediaCodecInfo info) {
String name = info.getName();
if (VERSION.SDK_INT >= 21 && name.startsWith("OMX.qcom.")) {
return true;
} else {
return VERSION.SDK_INT >= 23 && name.startsWith("OMX.Exynos.");
}
}
I doubt webrtc did not support codec like OMX.google.xxxxx . But I can't modify this code, how can I modify it so I can have a verification.
By the way, this is my webrtc implementation in gradle, if it helps:
implementation 'org.webrtc:google-webrtc:1.0.28513'
The AWS webrtc code is from AWS webrtc demo App, you can get here:awswebrtcdemoapp
And I'm sorry I can not offer my source code.
WebRTC Android only support qcom and Exynos hardware H264 encoders, you can change isHardwareSupportedInCurrentSdkH264 in HardwareVideoEncoderFactory to support other platforms such as OMX.hisi, OMX.MTK.
And then build the WebRTC to use libwebrtc.jar and libjingle_peerconnection_so.so in your project instead of
implementation 'org.webrtc:google-webrtc:1.0.28513'
how to download and build WebRTC Android:
https://webrtc.github.io/webrtc-org/native-code/android/
I made an android application that returns to the console some Linux commands.
In this case I want to find my wlan0 ip and my wlan1(when is connected) ip.
I've got the full text returned by ifconfig command. The problem is how can get into 2 variables these 2 IPs?
I Tried to substring after inet word but there are more than 1 word with inet. What is the optimal solution for this?
This is my string :
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 16436
inet 127.0.0.1 netmask 255.0.0.0
inet6 ::1 prefixlen 128 scopeid 0x10<host>
loop txqueuelen 0 (Local Loopback)
RX packets 37 bytes 7123 (6.9 KiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 37 bytes 7123 (6.9 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
p2p0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
inet6 xxxxxx prefixlen 64 scopeid 0x20<link>

RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
wlan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.0.100 netmask 255.255.255.0 broadcast 192.168.0.255
inet6 xxxxxxxxxxx prefixlen 64 scopeid 0x20<link>
ether xxxxxxx6 txqueuelen 1000 (Ethernet)
RX packets 1504 bytes 817297 (798.1 KiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 686 bytes 126080 (123.1 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
Please note that I don't care about :p2p0 or lo section, only wlan0 and wlan1(when is connected).
What I want is to save 192.168.0.100 into a String ip;
Thanks in advance!
I am not sure if i understood what you trying but i think Regular Expressions
is a possible way to go
I am use Netty ( a java network framework) to server UDP request .
I found the
SO_RCVBUF
and
/proc/sys/net/core/rmem_default
and
/proc/net/udp
output confusing:
By the manual of socket( man 7 socket) It explains :
rmem_default
contains the default setting in bytes of the socket receive
buffer.
rmem_max
contains the maximum socket receive buffer size in bytes which
a user may set by using the SO_RCVBUF socket option.
and the /proc/net/udp show's the udp receive queue size :
sl local_address rem_address st tx_queue rx_queue tr tm->when retrnsmt uid timeout inode
60: 00000000:2F3C 00000000:0000 07 00000000:0003E094 00:00000000 00000000 500 0 2224362 2 ffff810066908cc0
I can get the SO_RCVBUF = 12904, but the rx_queue size is 254100(3E094), and rmem_default is 262142
my confuse is, why the SO_RCVBUF not equals to the rmem_default, and why the queue size not equals the SO_RCVBUF (but larger than it ) ?
It seams the ctx.channel().config().getOption(ChannelOption.SO_RCVBUF)'s value is half of /proc/sys/net/core/rmem_default and the real receive buffer size( queue size ) is also the value of /proc/sys/net/core/rmem_default
so why ctx.channel().config().getOption(ChannelOption.SO_RCVBUF) not equals to the system's config ?
The accepted answer is wrong. The correct alignment is:
tx_queue rx_queue
00000000:0003E094
So rx_queue is 0x0003E094 or 254100. This can be confirmed using netstat -unlp | grep pid , Recv-Q is second column. Example output:
cat /proc/net/udp
sl local_address rem_address st tx_queue rx_queue tr tm->when retrnsmt uid timeout inode ref pointer drops
8101: 41FD080A:06A5 00000000:0000 07 00000000:00005A00 00:00000000 00000000 1000 0 3892411 2 0000000000000000 0
netstat --udp -nl

You seem to have misread the output. When you line up the columns properly, rx_queue is zero.
I have been experiencing this issue for a while now. A quick explanation of the system:
A simple application will read in data over a tcp connection. The application uses Socketchannel object to establish a data communication line. The connection to hardware is established, and the application processes roughly between 400 - 700 packets before throwing the error:
at sun.nio.ch.SocketDispatcher.read0(Native Method)
at sun.nio.ch.SocketDispatcher.read(SocketDispatcher.java:43)
at sun.nio.ch.IOUtil.readIntoNativeBuffer(IOUtil.java:218)
at sun.nio.ch.IOUtil.read(IOUtil.java:186)
at sun.nio.ch.SocketChannelImpl.read(SocketChannelImpl.java:359)
I suspect it has to do with the operating system (windows 7) buffer, although I have tried a few work arounds (increasing JVM heap size, and creating additional registry variables for TCP settings), but with no luck.
Inspecting packet data using wireshark, the following information can been seen just as the error occurs
[TCP Window Full] 5001 > 49995 [PSH, ACK] Seq=123177 Ack=1 Win=200 Len=176
[TCP ZeroWindow] 49995 > 5001 [ACK] Seq=1 Ack=123353 Win=0 Len=0
Which is then followed by a series of
[TCP Dup ACK 144#1] 5001 > 49995 [ACK] Seq=123353 Ack=1 Win=200 Len=0
until the connection is terminated.
I am hoping perhaps someone has had a similar issue in the past,or could offer some guidance on something I may be overlooking.
Here is sample code where data is read, and the error is thrown.
try{
do{
socketChannel.read(syncBuf);
start = syncBuf.get(0);
int b = start;
System.out.println("start byte is " + b);
syncBuf.clear();
}while(start != INIT_BYTE);
}catch(Exception e){
e.printStackTrace();
}
packetBuf.order(ByteOrder.LITTLE_ENDIAN);
packetBuf.clear();
try{
while(socketChannel.read(packetBuf) != 206){
nrBytesRead += socketChannel.read(packetBuf);
}
}catch(Exception e){
ApplicationLogger.log("Error at INIT_BYTE loop ", "ERROR");
}
Many thanks.
I think you have a problem here:
while(socketChannel.read(packetBuf) != 206)
{
nrBytesRead += socketChannel.read(packetBuf);
}
socketChannel.read(packetBuf) will return the number read this time, not the total, and I guess that's what 206 is, the total read.
You probably want to do that:
do
{
nrBytesRead += socketChannel.read(packetBuf);
}
while (nrBytesRead != 206)
I have a java app program run on centos 6.3 and tomcat 7 as the app container, currently I meet one error : java.io.socketexception Maximum number of datagram sockets reached
we use MulticastSocket class to send message. when this error happened, I check the current server UDP socket count with command: ss -s
Total: 212 (kernel 248)
TCP: 70 (estab 15, closed 44, orphaned 0, synrecv 0, timewait 40/0), ports 22
Transport Total IP IPv6
* 248 - -
RAW 0 0 0
UDP 40 40 0
TCP 26 26 0
INET 66 66 0
FRAG 0 0 0
and I also check the
ulimits -n
The default setting is 32768, seem UDP socket count not exceed max count.
Any ideas for this error?
we use MulticastSocket class to send message.
Why? You only need a MulticastSocket to receive multicasts.
Obviously you are leaking MulticastSockets. Presumably you are creating a new one per message and never closing it.
