rtp

I had a RTP Stream socket, receiving a JPEG Stream, from a samsung network camera. I dont know much about how JPEG format works, but i do know that this incoming JFIF or JPEG stream is giving me the JPEG header +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Type-specific | Fragment Offset | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Type | Q | Width | Height | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ and then +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Restart Interval |F|L| Restart Count | +-+-+-+-+

Using the following code to start the stream raspivid -t 0 -h 720 -w 1080 -fps 25 -hf -b 2000000 -o - | \ gst-launch-1.0 -v fdsrc \ ! h264parse \ ! rtph264pay \ ! gdppay \ ! udpsink host="192.168.0.11" port=5000 Then I provide a simple webpage with a video tag: <video id="videoTag" src="h264.sdp" autoplay> <p class="warning">Your browser does not support the video tag.</p> </video> The src references the following SDP file: v=0 m=video 5000 RTP/AVP 96

I am using live555 and ffmpeg libraries to get and decode RTP H264 stream from server; Video stream was encoded by ffmpeg, using Baseline profile and x264_param_default_preset(m_params, "veryfast", "zerolatency") I read this topic and add SPS and PPS data in the every frame, which I receive from network; void ClientSink::NewFrameHandler(unsigned frameSize, unsigned numTruncatedBytes, timeval presentationTime, unsigned durationInMicroseconds) { ... EncodedFrame tmp; tmp.m_frame = std::vector<unsigned char>(m_tempBuffer.data(), m_tempBuffer.data() + frameSize); tmp.m_duration =

I am looking for the SIP stacks for Android and iPhone. I found plenty of similar questions, which are sometimes quite old... I do not care too much if the solution is commercial (but this is preferred) or open source. So far I found Commercial solution from RADVISION for Android Open source SIPHONE for iPhone LINPHONE which covers both platforms. Gingerbreadhas built-in SIP stack - but seems that it has some limitations and might be removed by MNO... My questions are: Does anybody has good/bad experience with above solutions? Do you develop and publish an application with use of above

Is it possible to read an absolute timestamp from an H.264 stream sent trough RTSP from an Axis camera? It will be necessary to know when the frame has been taken by the camera. Thanks Andrea as Ralf already said - the RTP timestamps are relative to a random clock - they are only useful for computing the difference between two frames (or RTP-packets in general). For synchronizing these relative values to a wall clock you can use the RTCP sender - just have a look on the links Ralf provided. For Axis-products using H.264 this works pretty good. In case you're also using MPEG4, the Axis firmware

I'm currently trying to use Android as a Skype endpoint. At this stage, I need to encode video into H.264 (since it's the only format supported by Skype) and encapsulate it with RTP in order to make the streaming work. Apparently the MediaRecorder is not very suited for this for various reasons. One is because it adds the MP4 or 3GP headers after it's finished. Another is because in order to reduce latency to a minimum, hardware accelaration may come in handy. That's why I would like to make use of the recent low-level additions to the framework, being MediaCodec , MediaExtractor , etc. At the
