• VB.Net Stream/Port Image To FFmpgeg using Standard Input

  31 janvier 2015, par Zakir_SZH

  hope all active member of this community are fine.
  in my project i need to convert several image to video file.
  Currently i have to first save the images to PC then use ffmpeg to read that images from the pc and convert it to movie.

  But rather than save image to pc, i want to send image directly to ffmepg using StandardInput call. Ffmped does support that. but i don’t know how to use that.

  i have search internet a lot and all i found is getting output/response from ffmpeg using standarderror as ffmepg write to standerror instead of standardouput.

  below link something similar to what i look for that that code don’t work and also that use mp3 file instead of image/graphics.

  http://tiku.io/questions/3075356/convert-wma-stream-to-mp3-stream-with-c-sharp-and-ffmpeg

  can any one help me out, how to send image from picturebox/graphics object to ffmpeg one by one ?

  thanks in advance

  best regards

• Receiving and Manipulating RTSP stream using FFMPEG library in Java Application

  14 janvier 2015, par Bilal Ahmed Yaseen

  Hope you all be fine and doing great.

  I am currently working on a Java Web Application. I am getting Streaming video using RTSP URL. This URL is like :

   rtsp://---.---.---./6ca714ae28e52f31

  I have been able to capture video, diplay/listen it and store it in .mp4 file using FFMPEG with the following command :

  fmpeg -i rtsp://username:password@---.---.---.---/6ca714ae28e52f31 -f mov e:/bay.mov (with authentication)

  Now, I want to achieve the same in my Java application using ffmped library. I am sure if all this possible through commands then It will also be possible using its library. But unfortunately couldn’t get any working useful material regarding this on web.

  So, I simply want to ask that :

  1.  How can I fetch Streams using this RTSP URL in my Java Application with FFMPEG library
  
  2.  How can I Manipulate this fetched streaming such as start, stop, end etc.
  
  3.  How can I store this streaming in media file in playable form in any specified format.

  I have found a FFMPEG’s Java Rapper JJMPEG. Now I have two options either to issue FFMPEG command to CMD using Java Application or use JJMPEG library directly. Don’t know which one will be better choice.

  Thanks for your time and considerations.
