RTP packets detected as UDP
8 juillet 2024, par fritzHere is what I am trying to do :



WebRTC endpoint > RTP Endpoint > ffmpeg > RTMP server.



This is what my SDP file looks like.



var cm_offer = "v=0\n" +
 "o=- 3641290734 3641290734 IN IP4 127.0.0.1\n" +
 "s=nginx\n" +
 "c=IN IP4 127.0.0.1\n" +
 "t=0 0\n" +
 "m=audio 60820 RTP/AVP 0\n" +
 "a=rtpmap:0 PCMU/8000\n" +
 "a=recvonly\n" +
 "m=video 59618 RTP/AVP 101\n" +
 "a=rtpmap:101 H264/90000\n" +
 "a=recvonly\n";



What's happening is that wireshark can detect the incoming packets at port 59618, but not as RTP packets but UDP packets. I am trying to capture the packets using ffmpeg with the following command :



ubuntu@ip-132-31-40-100:~$ ffmpeg -i udp://127.0.0.1:59618 -vcodec copy stream.mp4

All I get is a blinking cursor and The stream.mp4 file is not written to disk after I exit (ctrl+c).



So can you help me figure out :



- 

- why wireshark cannot detect the packets as RTP (I suspect it has something to do with SDP)
- How to handle SDP answer when the RTP endpoint is pushing to ffmpeg which doesn't send an answer back.







Here is the entire code (hello world tutorial modified)

How can I compress or change the resolution of the video very fast with FFmpeg ?
28 mai 2017, par RaresI would like to compress or change the resolution of the video before sending it to server but I don’t want to take too long. For example for the following code a video with size 100MB it takes 2-3 min to resize it to 10MB. Can I do it faster without losing too much quality ?

Launching ffmpeg from inside my C code doesn't convert video stream from fifo
13 mai 2017, par abraxas1(Beaglebone Black, ubuntu 16.04 linux 4.4.62-ti-r99)
I have a raw h264 feed coming into my C program (into a callback from a custom API) and then I named-piped the raw h264 to a file and this CLI command converts that file successfully.
ffmpeg -report -re -framerate 30 -y -f h264 -i orbi_0148.cam1.h264 -c:v copy -an -video_size 1920x1080 -f mp4 orbi_0148.cam1-1.mp4
I then try to launch this command from my program with the same options using execv(),
first mkfifo the fifo’s,
then launch ffmpeg (shown below) starts the streaming form the cameras to my callback function, and out to the fifos.
I close the fifos at the end of video recording, and don’t get any file created and get this output, which I don’t understand at all.
(the successful command line output follows below this output generated from execv())
thanks, any help much appreciated.
hardware has come in now and the spot light is on me.(execv output with options -report -y -i /tmp/fifocam3.h264 -c:v copy -an -video_size 1920x1080 -f mp4 /media/sd-card/orbi_0140.cam3.mp4)
