  • How can we feed bytearray of an image in input of ffmpeg for doing direct operation for live streaming to RTMP server

    31 janvier 2017, par Raj Kumar Singh

    What I am doing now is :

    I have a stream from a source, that give me byte array for each frame. I have to save that byte array to JPEG file. Each of the frames are being saved in memory. Then I’am streaming those JPEG to server using the FFMPEG command.

    What I want to do is :

    I want to skip the step of storing each frame as JPEG. I want to directly stream the byte array to RTMP server.

    The FFMPEG command I am using is :-

    ffmpeg -framerate 10 -i c:\Stream\img%03d.jpg -f flv rtmp://192.168.243.195/live/ac71e

  • C# Using NReco FFMpegConverter to take live video screenshots

    21 novembre 2014, par Lance Bloom

    I have an an application running as an Azure Web Role where I want to take screenshots of live RTSP video streams on a Wowza server. I am using the NReco FFMpegConverter wrapper. I am having issues with consistency. Sometimes the code doesn’t execute at all, sometimes it executes right away, sometimes it take 2-3 minutes for the screenshot to be created. I’ve tested this on static (not live) mp4 videos and everything is executed flawlessly (within 1-2 seconds).

    Stream thumb1 = new System.IO.MemoryStream();
    

    
var ffMpeg = new NReco.VideoConverter.FFMpegConverter();                
    
ffMpeg.GetVideoThumbnail("rtsp://99.99.99.99:1935/streamurl", thumb1);
    

    
//Code to upload file to blob storage
    
blob = testContainer.GetBlockBlobReference("test.jpg");
    

    
thumb1.Seek(0, SeekOrigin.Begin);
    
blob.Properties.ContentType = "image/jpg";
    
blob.UploadFromStream(s);

    The error I get during failed execution is "Output file #0 does not contain any stream". I am really curious why it takes 2-3 minutes to get an output screenshot sometimes, while other times only a few seconds. Looking for any advice on how to improve this approach and still use the C# NReco wrapper.

    Thanks !
