Dump WebRTC stream to a file
20 novembre 2014, par MondainI’d like to capture the audio and video from a WebRTC stream to a file or pair of files, if audio and video require their own individual files. The audio and video are not muxed together and are known to be available on a set of server udp ports :
Port Encoding 5000 - VP8 video 5001 - RTCP (for video) 5002 - Opus audio @48kHz 2 channels 5003 - RTCP (for audio)
The SDP file / data is not available and DTLS may be used.
I would prefer to use avconv or ffmpeg to capture the stream, unless a better tool is suggested.
Edit : I’ve found that this as inquired will most likely not work. Until I hear otherwise, none of these tools support the initial DTLS handshake followed by the data transmission via SRTP.

ffmpeg video stream to app c# [on hold]
3 septembre 2014, par Alexey MedvedevI am trying to make a video mixer for online broadcasts. To do this, I use ffmpeg and C #. I had a problem with the transfer of the video stream from ffmpeg to my program. I would like to receive a stream of ffmpeg using network protocols (e.g. TCP, UDP or others) or capturing if from ffplay window, but I don`t how I can do it. Can you give me some ideas ?
For example, I have command for ffmpeg : "ffmpeg -i video1.mp4 -f mpegts udp:127.0.0.1:5000" or same command with other output formats or network protocols. How i can read video stream from the port and convert it to Bitmap ?
I need to send video stream from my program from computer A to my program to computer B. I write program on C#. I dont know how I can compress video which I must send between my computers and I decided to use Ffmpeg. Now, I can streaming video from my program in computer A to ffmpeg and compress it with parameters which I need.
On second computer I can read this steam using ffmpeg or ffplay, but I don`t know how I can get this stream into my program.
1) How can I get this stream in my program ? Which libraries can you recommend me ?
2) Do you know any libraries which can compress video, instead of using ffmpeg ? -
Gstreamer errors when streaming on windows
19 juillet 2014, par user2656632I tried to streaming video by gstreamer using this :
Sender :

Receiver :
gst-launch udpsrc port=5000 caps="application/x-rtp, media=video, clockrate=90000, encoding-name=MP2TS" ! rtpmp2tdepay ! ffdemux_mpegts ! ffdec_mpeg2video ! ffmpegcolorspace ! directdrawsink
