  • Fallback input for ffmpeg

    22 septembre 2018, par Daniel Cantarin

    I’m doing some transcoding from a third-party remote input stream that I do not control.

    This input stream has errors from time to time, that I would like to mitigate before sending the stream to my transcoding pipeline, avoiding this way some possible problems in the output.

    I have several ideas regarding different problems. But the most basic scenario I would like to set up is as follows : when the stream is down, or it somehow loses some frames, I want to fill that video gap with a secondary input (like a blank screen, for example).

    For this simple task, I would like to use ffmpeg. I know it can mix, let’s say, an input stream with a fullscreen black square static image. However, I have to deal with this other condition : ffmpeg would run in the same infraestructure for the actual transcoding pipeline. That infraestructure must use its computing power for rendering the output. So, whatever ffmpeg command I end up using should use the minimum possible computing power.

    My actual problem : if I use -vcodec copy, in order to use minimum CPU, I can’t alter the original stream. But if I alter the original stream (by mixing it with some other stream), the operation uses CPU.

    My question : Is there a way to use -vcodec copy, but with a fallback input (instead of a mixed one) for when there are video gaps in the primary stream ?

    Thanks in advance.

  • iOS video streaming to server using websockets

    6 septembre 2013, par user1516711

    Is it any way possible to stream video frames live from iOS SDK using AVCaptureSession to a remote server using WebSocket like SocketRocket ? What are pros and cons if it is possible ?

  • h264 real time video streaming

    7 septembre 2017, par Michal Gallovic

    If you have dynamically generated h264 frames on one end (server), how would you go about making a real time (low latency) video stream viewable in browser (client) ?

    In other words, what I’m trying to achieve is streaming graphically intensive c++ application from gpu server to browser.

    As a simple solution, I’m thinking of something like this :

    c++ app | ffmpeg | server | html5 client

    h264 frames created by application are sent to standard output, where ffmpeg is used to remux this stream into mp4 that is passed to server, which upon request can pass it to client.

    Is this a good approach ? Is that even possible to create a low latency 30fps video stream using this approach ?
