Hello i've one question. I create a rtp strem, and sdp file, from webcam. Now i have to obtain one rtsp stream. How i can do it?, i read online that i need rtsp server. Can i made it in java code? or can i excecute line command from ffmpeg to obtain it from rtp stream?

Yes sure we can use FFmpegFrameRecorder the same way as the ffmpeg command line program for that. Contributions of sample code are welcome.

of course.

                        recorder = new FFmpegFrameRecorder("rtp://192.168.88.241:5056", CAPTUREWIDTH, CAPTUREHRIGHT);
                        recorder.setInterleaved(false);
                        // video options //
                        recorder.setVideoOption("tune", "zerolatency");
                        recorder.setVideoOption("preset", "ultrafast");
                        recorder.setVideoOption("crf", "25");
                        recorder.setVideoBitrate(150000);
                        recorder.setVideoCodec(avcodec.AV_CODEC_ID_H264);
                        recorder.setFormat("rtp");
                        recorder.setFrameRate(FRAME_RATE);
                        recorder.setGopSize(GOP_LENGTH_IN_FRAMES);

this is the code for rtp stream, if i try to substitute rtp with rtsp not work. When run code, it blocks in record.start();
