How to get rtp(javacv ffmpeg) stream from VLC as client

15 avril 2015, par Sezertt

I 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); &lt;-- AV_CODEC_ID_H264

        frameRecorder.setFrameRate(25);           

        frameRecorder.setVideoBitrate(1024); &lt;--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 H264/90000

and 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

Can you lead me to the right direction ? What should I do to get fair quality and no lag using rtp ?

Ffmpeg iis smooth streaming credentioals

I use ffmpeg to stream live video to IIS publishing point by this command
```
ffmpeg -f dshow -i video="video device name":audio="audio device name" -pix_fmt yuv420p -f ismv http://localhost/test.isml
```
And it works properly. But when my publishing point has credentials - ffmpeg fails after one minute after starting with
```
av_interleaved_write_frame(): Unknown error
```
As I see I need to specify IIS publishing point credentials. But how ? Any ideas ?
