• File input of avformat_open_input in ffmpeg

  28 février 2016, par Justin Chang

  I’m trying to use function avformat_open_input in FFmpeg to open the file which contains Chinese word.

  For example :

  char* file="C:/測試/baby.mp4";
  
  
  
  avformat_open_input(&pFormatCtx, file, NULL, NULL);

  But, it seems to be failed.

  My question is how do I pass the file path which contains Chinese (or other languages except for English) ?

• How to publish or push the live stream to RTMP-Nginx server using php and FFmpeg ?

  27 juin 2020, par vijendar

  I want to push the live stream to the RTMP-Nginx server. I am recording the webcam and sending it to the PHP running server using the socket but couldn't find the proper way to push the stream on the RTMP-Nginx server. I am appending the stream after receiving through the socket. I have used this

  


  ffmpeg -re -i uploads/test.webm -vcodec libx264 -preset fast -maxrate 1500k -c:a aac -b:a 128k -ac 2 -ar 44100 -f flv rtmp://x.xx.xxx.xx/live/xxx

  


  to push on the RTMP-Nginx server. But it's executing on the very first received packet of the video stream and then terminated. I know It's not working with a continuous appended video stream. may be FFmpeg reading as a whole. Hoping for the right direction. Thanks in advance.

  


• Use FFMPEG to stream images from one client to another through IIS (or other) server

  20 avril 2012, par eselk

  I'm new to FFMPEG and maybe I should post this in their forums, but you guys here seem to know everything, so here goes. I have a client app that takes screen shots and saves them as images (256 color bitmaps currently, can change if needed), it does this at a rate of about 4 fps. I currently use my own socket code written in C# to push these to my socket server (also C#) running on a Windows 2008 server. That server then sends these images out to several clients that display them as they are received and also buffers them to allow for rewind, pause, etc, like a DVR. My current format requires approx 100KB per frame, and thus only works for a very small number of clients.

  I started looking at FFMPEG and the compression with MPEG1 and especially MPEG4 is amazing, and so is the quality. What I'm looking for is a basic guide, tutorial, or steps, to produce something similar to my current design, but using FFMPEG and actual video streaming. Ideally the player side could be something like Flash or anything that is easy to embed in a .NET WinForm (or a browser control I can host in the WinForm), and it would need to support buffering still so they can pause and rewind (about 5 or 10 mins, which seems like a lot, but remember this is only 4 fps and 256 color, about 1 or 2 MB per min in my testing).

  I see that FFMPEG, the command-line utility, and I assume the API, even has options for posting to a server via UDP or TCP, so maybe I'll use that instead of my own socket code. Ideally my app would feed images to FFMPEG library at a rate of 4fps as they come from the screen-shot unit, and it would send these up to my IIS server (or another server ?) which would then server them to client(s) that could use them similar to a YouTube video.
