How to get rtp(javacv ffmpeg) stream from VLC as client
15 avril 2015, par SezerttI am trying to play rtp stream from vlc player which I created using javacv. Here is the code :
FFmpegFrameGrabber frameGrabber = new FFmpegFrameGrabber("rtsp://10.6.0.147:554/ufirststream");
frameGrabber.start(); // First I take another stream
FFmpegFrameRecorder frameRecorder = new FFmpegFrameRecorder("rtp://239.31.31.69:4433", frameGrabber.getImageWidth(), frameGrabber.getImageHeight());
frameRecorder.setFormat("rtp");
frameRecorder.setPixelFormat(AV_PIX_FMT_YUV420P);
frameRecorder.setVideoCodec(AV_CODEC_ID_MPEG2VIDEO); <-- AV_CODEC_ID_H264
frameRecorder.setFrameRate(25);
frameRecorder.setVideoBitrate(1024); <--1024*1024*2
frameRecorder.start();
while (true) {
frameRecorder.record(frameGrabber.grab()); //grab from stream, stream with rtp
}If I choose my codec as AV_CODEC_ID_MPEG2VIDEO I can play the stream from VLC using rtp ://239.31.31.69:4433 with open network.
If I increase the quality using setVideoBitrate(1024*1024*2) the stream lags too much and if I decrease the quality is so bad.
I want to use AV_CODEC_ID_H264 as my codec to fasten things with better quality but i can’t play the stream from VLC getting error :
SDP required A description in SDP format is required to receive the RTP stream. Note that rtp :// URIs cannot work with dynamic RTP payload format (96).
I tried to get sdp using wireshark and then I realized rtp stream doesn’t have sdp :) so I tried to create my own sdp like this
c=IN IP4 239.31.31.69
m=video 4433 RTP/AVP 96
a=rtpmap:96 H264/90000and this
v=0
c=IN IP4 239.31.31.69
a=recvonly
t=0 0
m=video 4433 RTP/AVP 99
a=rtpmap:99 H264/90000
a=fmtp:99 packetization-mode=1;profile-level-id=42c01e;sprop-parameter sets=Z0LAHukBQHsg,aM4G4g==;but both seems to fail similar to this

RTSP streaming on Android client using FFMpeg
10 août 2013, par rurtleI am working on a hobby project the goal for which is to develop an Android application capable of streaming live feeds captured through web cams in a LAN setting using FFMpeg as the underlying engine. So far, I did the following -
A. Compiling and generating FFMpeg related libraries for the following releases -
FFMpeg version : 2.0
NDK version : r8e & r9
Android Platform version : android-16 & android-18thisthisthisthis
Toolchain version : 4.6 & 4.8
Platform built on : Fedora 18 (x86_64)B. Creating the files Android.mk & Application.mk in appropriate path.
However, when it came to writing the native code for accessing appropriate functionality of FFMpeg from the application layer using Java, I'm stuck with following questions -
a) Which all of FFMpeg's features I need to make available from native to app layer for streaming real-time feeds ?
b) In order to compile FFMpeg for Android, I followed this link. Whether the compilation options are sufficient for handling *.sdp streams or do I need to modify it ?
c) Do I need to make use of live555 ?I am totally new to FFMpeg and Android application development and this is going to be my first serious project for Android platform. I have been searching for relevant tutorials dealing with RTSP streaming using FFMpeg for a while now without much success. Moreover, I tried the latest development build of VLC player and found it to be great for streaming real-time feeds. However, it's a complex beast and the goal for my project is of quite limited nature, mostly learning - in a short time span.
Could you suggest some pointers (e.g. links, documents or sample code) on how can I write the native code for utilizing FFMpeg library and subsequently use those functionality from the app layer for streaming real-time feeds ? Moreover, will really appreciate if you could let me know the kind of background knowledge necessary for this project from a functional standpoint (in a language agnostic sense).
