  • How to decode a live stream encoded using FFMPEG ?

    5 mai 2016, par Amber Beriwal

    I am not very proficient with C programming and working on live streaming using FFMPEG. Basically, I want to put a watermark on a live streaming video.

    Using FFMPEG, I have been able to record a video from webcam, encode it and send to some ip:port using UDP. Now, my receiver(written in Java) is receiving the data in packets but I don’t know how to decode it for editing or play it. If I use ffplay, it plays it automatically. I referred some links :

    Decoding Encoding Example

    Could anyone please tell, how can I proceed for the solution. Any hints would be appreciable.

    1. How the data is encoded. Is it some FFMPEG format or generic format ?
    2. If a live stream is coming, then what information does each packet contains ? Whether it is a complete video itself or a portion of complete video file ?

  • Is Java fast enough to do live screensharing ?

    10 mars 2012, par user1260501

    For the past few months, a developer and I have been working on a screensharing applet that streams to a media server like Wowza or Red5, but no matter what we do, we have about 5 seconds of latency, which is too long for a live application where people are interacting with each other. We've tried xuggle, different encoders, different players, different networks, different media servers, and even streaming locally, there's significant latency.

    So, I'm beginning to wonder…

    Is Java fast enough to do live screensharing ?

    I've seen lots of screen recording applets written in Java, but none of them are streaming live. Everything that's done live, such as GoToMeeting, seems to use C++. I'm thinking maybe there's a reason.

    It's not a compression problem. Using ScreenVideo, we've compressed an hour-long stream down to about 100 MB, and we have plenty of bandwidth. The processor isn't overloaded doing the compression, either, but it seems to be taking too much time. We are getting the best results from some code pulled out of BigBlueButton, but still, the latency is terrible.

    Streaming the WebCam, on the other hand, is nice and snappy. Almost no latency at all. So, the problem is the applet.

    The only other idea I can think of is somehow emulating a WebCam with Java. Not sure if that would be faster or not.

    Ideas ? Or should I just give up on Java and do this in C++ ? I would hate to do that, because then I would have to create different versions for different platforms, but if it's the only way, it's the only way.

  • FFMPEG Live Stream Convertion

    22 décembre 2016, par Grace De Paz

    Is is possible for ffmpeg to convert a live stream mjpeg format to mp4 then pushes it to localhost or any server ? I tried this using vlc using below command but it doesn’t work

    vlc http://[ip]:[port]/api/cameras/7589145c-cbb4-4ae0-98aa-74481b62b8a4/live :sout=#transcode{vcodec=h264,scale=Auto,acodec=mpga,ab=128,channels=2,samplerate=44100}:http{mux=ffmpeg{mux=mp4},dst=:8080/test.mp4} :sout-keep
