• Streaming video with node

  14 septembre 2016, par Kei Taylor

  I am attempting to stream video with from my built-in Mac OSX webcam to a node server. My intent is to parse the video data I receive with ffmpeg once it reaches the server. This is my first time trying to manipulate video.

  My problem is, right now I am unable to use VLC to send data to a node server. I am opening a stream with VLC by using the "Open Network" option, and streaming through what I think is my local IP, port 3000. However, I am not sure how to get from that to opening the stream on a node file. Also, I am not able to open the stream on the same computer and view it (I mean, when I click open stream on VLC and plug in my local IP and port 3000, I can’t view the stream I’m sending out).

  Clearly, I am doing something wrong. As this is my first experience with VLC and video transmission, its possible I’m missing something important. Its my impression that I should be able to stream to an ip and port using VLC, and then set up a node server that listens for data from this same port and ip, recieves chunks of video data, and formats it using FFMPEG.

  My questions are :

  1) Is this understanding accurate ?
  2) Does anyone have guidance on how I would transmit with VLC and read with FFMPEG in node (and then send to another client ?)
  3) Failing that, any guidance on the simple question of how to transmit a video stream using VLC and then open it using VLC on the same computer ?
  4) Any resources explaining how to do this ?

  I’d really appreciate layman’s, baby explanations. I’ve found a few blog posts that have illuminated issues, but been a bit difficult to follow.

  Thanks, as always.

• Replace absent frames with "connection issue" picture

  5 septembre 2016, par exebook

  We have some recorded web chat sessions, that have periods of absent frames. The frames are absent due to connection issues of on one of the talkers. When we playback those media files (recordings), the last available frame prior to connection problem is shown. When you scroll in that problem area, you get varying results depending on the player you use, but normally the slider will jump like crazy to the next available frame. Instead we want the predefined picture to be show in place of every absent frame, and scroll should work nicely through those areas. How to achieve that ? Perfectly the image would be an animated GIF, but static JPEG is also OK.

  There could be an special case, like when only one or just a few frames are absent, and showing a placeholder image is not good, instead the last frame could be painlessly repeated. But when the frames are absent for longer than one second, the placeholder should be displayed. Can this special case be also addressed ?
