  • 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.

  • I want to place a heart transition I made between 2 videos with 2 blank png images with alpha , with a 4 sec transition in mkv format with overlap

    14 juillet 2022, par Christopher

    I want to place a heart transition I made that has 2 blank png images with alpha channel, that has a 4 sec heart transition that is in mkv format. I want to overlap the last image of the 1st video, with the transition video for 2 seconds, and overlap the first image of the 2nd video for 2 seconds. This would allow a heart transition, between 2 baby animals, between the clips that make up the videos. I have conceived a way to automate the assembly of over 1800 clips into videos, and this is a part of it. Sorry about the absence of clarity in my question, I hope this makes it clear, what I am trying to accomplish.

    


  • Could you please explain what the ffmpeg script does ?

    18 juin 2022, par Stariy

    There is this script :

    


    ffmpeg.exe -t 1 -i "D:\input\3.mp4" -ss 1 -i "D:\input\3.mp4"  -i "D:\input\3.mp4" -filter_complex "[1]zoompan=z='if(lte(mod(time,2),1),2,1)':d=1:x='iw/2-(iw/zoom/2)':y='ih/2-(ih/zoom/2):s=1920x1070:fps=25/1'[s0];[0][s0]concat=n=2 [outv]" -map [outv] -map 2:a -b:v 500k -s 1920x1070 -c:v h264 -vsync 2 "D:\output\3.mp4" -y

    


    I need to understand what he is doing, comment on each step so that I understand. Why are the three input files the same, what's going on at all ? I really hope for you.
