rtp

I need to detect MPEG4 I-Frame in RTP packet. I know how to remove RTP header and get the MPEG4 frame in it, but I can't figure out how to identify the I-Frame. Does it have a specific signature/header? Ok so I figured it out for h264 stream. How to detect I-Frame: remove RTP header check the value of the first byte in h264 payload if the value is 124 (0x7C) it is an I-Frame I cant figure it out for the MPEG4-ES stream... any suggestions? EDIT: H264 IDR This works for my h264 stream ( fmtp:96 packetization-mode=1; profile-level-id=420029; ). You just pass byte array that represents the h264

My target is to have a push-to-talk chat app in GSM/UMTS/LTE networks; initially I wanted use multicast addresses and peer-to-peer without overload the server; unfortunatly, after deep investigation, I discovered that multicast is not allowed in GSM/UMTS/LTE networks, therefore I have to use the server in order to bounce the VoIP packets. I' don't like very much this solution because I have to overload the server, but I didn't find any better solution. If you have an alternative solution is very much apprieciated... Therefore I have to send VoIP from an android client to a server (PC), and

I'm new to Android and socket programming. I want to create an android application that transfer video live from device camera to PC. What first i do is to get a raw video data from PreviewCallback arguments and convert it to an RTP Packet. I was just using JLibRTP to do this. Regarding to transfer the packet i think, there are some related class: RtpPkt, RtpSession, and RtpSocket. Here is my glance code: DatagramSocket rtpSocket = new DatagramSocket(); DatagramSocket rtcpSocket = new new DatagramSocket(); RtpSession rtpSession = new RtpSession(rtpSocket, rtcpSocket); public void

I want to stream video recording from my android phone to network media server. The first problem is that when setting MediaRecorder output to socket, the stream is missing some mdat size headers. This can be fixed by preprocessing that stream locally and adding missing data to stream in order to produce valid output stream. The question is how to proceed from there. How can I go about output that stream as an RTMP stream? MrGomez First, let's unwind your question. As you've surmised, RTMP isn't currently supported by Android. You can use a few side libraries to add support, but these may not
