  • What would be the best strategy to take a RTP stream and send it to an RTMP server ?

    27 novembre 2014, par matiasinsaurralde

    I’m receiving a RTP/UDP from a hardware encoder, I have tried ffmpeg, so it takes this input and outputs the stream as FLV (it’s being sent to NGINX, nginx-rtmp-module). However I’m not able to play the stream smoothly once it’s received by nginx, some frames are broken or lost, etc.

    I think that my CPU is too slow for this format change (FLV) and/or ffmpeg is missing a lot of RTP packets. Any ideas ?

  • A random pixel on a keyframe. (ffmpeg)

    5 juin 2013, par Chris Russo

    Hello folks of SO !

    We're trying to do some very small and simple code in PHP to generate a variation of a video, using always the same file.

    The script would have to make a small pixel mark, on random or specific frame of the video file, and this would have to be streamed in real time.

    Here's some pseudo code to explain my idea :

    $frame = $_GET[frame];
    
$videofile = 'video.avi';
    

    
make_random_red_pixel_mark($videofile, $frame);

    Does anyone know if this is possible using ffmpeg ? As well, it is of extreamly importance for us, to execute this procedure as fast as possible.

    A solution that would imply reprocessing the whole video, won't be useful for our purposes. It should be something like a closed caption, or a quick image / overlay filter that could be applied without an entire video reprocessing. As well, we can't put the overlay using Javascript nor any HTML approach, since the actual manipulation has to be on the video file itself.

    The quality, and framerate of the original video, should be kept intact. Perhaps some other PHP module or software that could be execute from PHP using an exec() ?

    Any recommendation ?

    Thanks in advance !!

    More information :

    1) It's possible for us to apply this procedure on any frame we want to, so we could use a "keyframe" in order to avoid the decoding and reencoding of an entire GOP.

    2) As previously stated, the video stream would have to flow in real time.
