• How can I stream images from a remote server to a mobile app in real-time ? [closed]

  1er mars 2024, par Tharunkumar Ampolu

  I have a setup where I connect to a remote server via SSH to retrieve images captured by a robot. Currently, I am using scp to transfer these images to my local system, where I then use FFmpeg to convert them into a video for storage.

  


  However, I would like to explore the possibility of converting these images into a video on-the-fly as they are added to the remote server folder, with the goal of streaming this video feed to a mobile app.

  


  My requirements are as follows :

  


  The image stream needs to be transmitted to the mobile app in real-time.
I would prefer to avoid storing the images locally and instead stream them directly from the remote server to the mobile app.
The streaming solution should be scalable and support a high frame rate (30fps).
Could anyone suggest an approach or provide guidance on how to achieve this ? Specifically, I'm interested in methods for continuously converting images into a video stream on the remote server and then streaming this video feed to a mobile app in real-time.

  


  Any insights, code examples, or recommendations for tools and libraries that could help accomplish this task would be greatly appreciated.

  


• How to implement HTTP Live Streaming server on Unix ?

  11 juillet 2019, par alex

  I just realized that Apple required HTTP Live Streaming in order to view videos in iPhone apps. I was not aware of this before... I am now trying to understand what this involves so I can decide whether I want to do the work and make the videos available in 3G or limit video playing to users who are connected to wi-fi.

  I read the overview provided by Apple, and now understand that my server needs to segment and index my media files. I also understand that I don’t have to host the content to be able to stream it (I can point to a video hosted somewhere else, right ?).

  What’s not clear to me at this point is what to implement on my server (Ubuntu Hardy) to do the actual segmenting and indexing on the fly (once again, I do not host the videos I want to serve).

  I found a link explaining how to install FFmpeg and X264, but I don’t know if this is the best solution (since I have an Ubuntu server, I can’t use the Apple Live Streaming tools, is it correct ?). Also, I do not understand at which point my server knows that a video needs to be converted and starts the job...

  Any feedback that could help me understand exactly what to do on the server side to be able to stream videos on my iPhone app in 3G would be greatly appreciated ! (Oh, and just it makes any difference, my app back-end is in Rails)
